Need help. Boiler Immergas eolo star 24, changing heating pipes, therefore, there is no pressure in the heating circuit (error 10), can the hot water circuit be used somehow?
It is possible if you create pressure in the heating circuit. For example, put valves on the supply and return of the boiler, close them and, through make-up, create a pressure of 1 bar in it, along the heating circuit. And that's all. The unit will run on hot water.
Boiler Eolo Mythos 24. I did the installation myself. Gorgaz arrived, plugged it in and that's it. I adjusted the coefficients. There are no questions about work. But in the kit there were several washers for ventilation. Gorgaz said that it is not necessary to install them, only I have doubts. When the boiler is operating outside, there is a persistent smell of gas. It seems that without a washer, part of the gas does not have time to burn out and flies out. Rates set to minimum. So should I put the puck or not? And what? There is just a washer, there is a transverse overlap in the middle.
The washer had to be installed during installation, depending on the length and type of the chimney, according to the installation instructions for the boiler. The unit must be set up by a specialist with a pressure gauge.
Salus IT500 look, it works via the Internet. There is also a TEPLOCOM GSM heat informer, it monitors and controls the heating system from a phone or smartphone via GSM. Air temperature control, coolant, leakage sensor, 220V network, control and configuration via SMS.
In the spring I plan to carry out gas. Got a choice gas boiler. The boiler will stand in the kitchen, hinged turbocharged. In the local city gas company, immergas boilers are recommended, since right there (in the same city) there is an official service center. The question arose between the two models EOLO STAR 24 and EOLO MYTHOS 24. In the second, there are two heat exchangers for hot water supply, separate, unlike the first, where everything is enclosed in one. Is it important that the heat exchangers in the boiler are separated?
Yes, the second one is better.
The question arose of switching to summer mode, and for one thing I want to twist the heated towel rail.
Can you tell me how to close the heating circuit? Boiler Eolo mythos 24.
Which taps are larger - this is heating (3/4), which are smaller (1/2) - hot water.
The imergaz eolo mitos 24 boiler operates when hot water is used, the pressure in the water supply system is 1.5-2 atmospheres. By reducing the minimum burner power to a minimum, the situation became a little better, but provided that the temperature was set to 48-50 degrees. The unit does not cycle and modulates the burner at minimum power. I tried to draw water from a tap (ball), without a mixer - everything is fine, even at 40 degrees it does not clock. It turns out a weak water intake at the mixer. Does anyone know if there are mixers with a large capacity, or are they standard?
And you check the mixer itself, its mesh and eyeliner.
Boiler eolo star 24 3e. When an additional pump is running on a warm floor, the hot water in the tap does not reach the set temperature (I set it to 50, but it gives out 38). I turn off the additional pump, the device heats up perfectly. How to solve this problem?
I suspect an improperly assembled heating system. With DHW heating three-way valve shuts off the heating and drives the coolant inside the boiler, which heats the water through the heat exchanger. And here it turns out that the floor heating pump continues to work and opens the 3-way one. You can do it, here are the options: Install, as expected and recommended by all manufacturers, a hydraulic gun with manifolds and pumps. Install a one-way valve (normally closed). Connect the floor heating pump to the control board.
Tell me, we have an immergas boiler, a thermostat (thermostat) SALUS T102. Two days ago, we noticed that the temperature was set to 19 on the thermostat, the unit works without interruption and the temperature shows 23. We replaced the batteries in the thermostat, it also works, restarted it, it seemed to turn off and maintain the temperature set by the thermostat. Today, the same story again, on the thermostat 18, and it works, with readings of 20. The temperature of the coolant is 60. What could it be? Could the thermostat be faulty?
Check the contacts and the wire itself carefully. Perhaps somewhere something is shortening.
The Eolo Mini 28 boiler is installed and connected to the system. When the hot water supply is turned on - warm water flows only with a strong pressure of water, the secondary heat exchanger has been cleaned.
Dismantle the flow restrictor installed in the upper part of the DHW flow sensor or the plastic coarse filter in the lower part of the sensor, or replace the flow heat exchanger.
The boiler gives error 12, what should I do?
Check the set parameters (P9) in the boiler and set them according to the factory values.
Failure of the Nike Star 24-3 E boiler. The problems began with the expiration of the warranty period. Now very often it gives an error 10. What is the problem and how to solve it?
Insufficient installation pressure. There is not sufficient measurement of water pressure in the heating system (error 10) to guarantee correct operation. Check that the system pressure is in the range of 1-1.2 bar.
Boiler Immergaz Eolo Star turbo, problem with the DHW circuit. I set the water temperature to 40, the water heats up to 40 and the boiler turns off (error 02 is displayed). Then it gives error 11. After that, when the water temperature drops, the device turns on again.
It is necessary to clean the fan and tubes on the air relay. And it is desirable to flush the DHW circuit for prevention.
Immergas Eolo Mythos - 24, gives error 06, tell me how to fix the problem?
Check temperature sensor.
The pressure rises, the make-up valve is closed. What better to do, change the tap or can only rubber rings on it?
Check the pressure in the expansion tank. But you may have to replace the tap or even the heat exchanger.
Error 01, the gas was turned off for one day. When turned on, the start glows red. Does not read the ignition of the burner, what should I do?
Press reset and set the temperature.
The Immergaz Nike Mini boiler is in operation. Water does not circulate. In the summer I cleaned the combustion chamber, removed the ash accumulated over 2 years and closed it back. The heating season has begun, several batteries are working. Dismantled, drained, filled with new fluid - no circulation. He blew air in one battery, in the rest water flowed under pressure. The result is the same - no heat. The device displays the set temperature. What is the reason? If the pressure in the expansion tank is low, can this affect the circulation in the system?
Have you cleaned the return filter? If not, then you definitely need to clean it, otherwise there will be no sense.
Installed and connected to the system boiler Imergaz Eolo Star 23 kW. Per month high flow gas - up to 500 with heating. How to make it faster to gain temperature when heating a house? You put 45 gr., gains temperature within 5 minutes. Can you do it faster?
Can. Parameter "P8" (see instructions) is factory set to "10". This means that after turning on the boiler will reach maximum power, if necessary, after 10 minutes. Set a different value - and enjoy!
The pump does not start, it gives error 27, I check the voltage, but it is not there, eolo old 24.
It seems that the relay on the board does not work, therefore - change the board.
Nike Mythos 24 2E boiler failure. Gives an error with code 02. Tell me what could be?.
Error 02 is either overheating of the boiler (the contacts of the safety thermostat set to 100 degrees open) or problems with the flame control circuit. The first option is easy to check: see what temperature the device shows when error 02 appears, and if the temperature is far from 100, short-circuit the thermostat and see if the error stops appearing. If it stops, change the thermostat. But if, when an error occurs, the boiler temperature is close to 100 gr. (more precisely - to 90 gr., it has no right to rise above, the burner automatically turns off), then you have a real overheating. Bypass the thermostat and do not try. The second option is more difficult, I recommend calling a service provider.
Tell me, what should be the gas pressure on the manometer? I installed a pressure gauge under the boiler and it shows 18 mbar, and in working condition 13 mbar.
The pressure is normal. The SIT 845 Sigma valve, found on most boilers, can be pressurized from 13 - 14 to 60 mbar and it will output what it is set to.
The boiler Immergas Nike Mini 24 3 E is installed and connected. It turns on for 3 seconds and immediately turns off and so on all the time. The boiler does not turn on at all, errors are not displayed, what could be?
It looks like the symptoms of error 04. The best thing contact the service, but if this is problematic, do the following: close the contacts of the limit thermostat; did not help - close the contacts of the minimum pressure switch; did not help - after turning on the fan, close the contacts of the smoke exhaust pressure switch (or it is also called "smoke exhaust monostat" or "air relay"). Determined a faulty element - change. Most often it is a smoke exhaust pressure switch.
Error 10 and nothing is pressed, blinking. Tried to turn on and off from the network, does not help.
Either the minimum pressure switch is damaged, or there is little water in the system (pressure less than 0.8 bar). Jump the relay contacts, the error will disappear. Or you don't have enough pressure. Look at the manometer.
Immergaz Eolo Mitos 24, in operation for two years, the fan whistled.
Try lubricating the fan bearing. Or change the fan.
Imergaz boiler, error 10 is on, pressure 0, how to increase pressure?
There is a screw - this is a make-up tap. Turn it counterclockwise (open) and from the DHW system (hot water supply) water begins to flow into the heating system (unless, of course, in DHW system there is some pressure). Next - look at the pressure gauge and when the pressure reaches 1.2 - 1.5, close the tap.
Immergas Mini Nike 24 boiler malfunction. Error 27 is on. Insufficient circulation. How to eliminate yourself? We have very hard water. I'm assuming something got screwed up somewhere.
It is possible that the dirt filter, which the installers had to install on the "return" pipe in front of the device, is clogged. Clean up. Perhaps the heating system is clogged. Rinse. Either one won't hurt. There may be problems with the pump. It's more complicated, the pump will have to be changed.
Installed and connected boiler Immergaz Eolo Star 24 3e. Why is there a small flow of water at the outlet?
Most likely, the boiler is already 1.5 - 2 years old, and the water is hard; At first everything was fine, and then less and less. If so, the water circuit in the heat exchanger is clogged with scale. Rinse should help. Perhaps the pipes of the water supply system itself are clogged.
We completed the installation, installation and start-up of the Immergaz boiler, worked for 3 years. The water pressure on the manometer is 0.5, the set temperature is 40 degrees. The boiler goes to heat and immediately the pressure in the water system rises to 3 and above, it is necessary to drain the water. If the heating is turned off, then when the water in the system cools, the pressure drops below the mark and the boiler no longer starts, it is necessary to add water. But before it didn’t work like that, and water constantly drips from the valve, and I can’t set more than 40 degrees - I have to drain the water.
These are clear symptoms of a malfunctioning expansion tank. Press the nipple on the expansion tank with a match. Possible options: Air went out, so the tank is working; Water went out - a tank for replacement. In the first case, connect an automobile pump to the expansion tank nipple and pump up a pressure of 1 atm. (on both pressure gauges, pump and boiler). In the second, turn off the heating taps suitable for the boiler (2 pcs), open the drain valve of the boiler heating circuit (below, plastic, next to the feed tap) - a certain amount of water will flow out; connect the car pump to the nipple and, without closing the make-up valve, start pumping. Water will start flowing from the drain tap again. Let it all flow out. Once the leak has stopped, close the drain valve and pump up the tank to 1 atm. (according to the pump manometer), unfasten the pump and open the tap for feeding the device. Bring the pressure (on the boiler manometer) to 1.2. After that, open the taps of the heating system
under the boiler and make-up tap, bring to 1.2 already in the entire system. What you now have: You have eliminated the malfunction at least temporarily - it looks like the nipple does not hold, if the defect recurs, you will have to change the nipple; in the second case you need expansion tank change or duplicate (insert an additional tank of the same capacity into the heating system in any convenient place). By the way, you have about a week to install a new tank; after you pumped it up, it will work normally for about a week, and then the air will dissolve in the water - and everything will happen again.
Immergas Eolo Star / Mini model errors
Immergas Nike Star/Mini Model Mistakes
The boiler is switched off - the indicator is off.
The unit is in standby mode - the yellow LED flashes occasionally.
Presence of flame - yellow indicator is on.
The device is blocked when the ignition of the flame has failed - the red diode is lit.
The device is blocked due to overheating - the red signal flashes.
The draft thermostat has turned on - the indicators flash together
Lack of water in the heating system - the LEDs flash in turn.
Faulty Nike Star / Mini boiler NTC probe or hot water NTC probe - flashing yellow.
Heating has low water circulation - red glows, yellow blinks.
The DHW system has a water leak - the red indicator flashes intermittently.
Operation in Chimney Sweep mode - red LED flashes continuously.
Ignition lock - red indicator lamp is on. Whenever heating or hot water production is required, the unit switches on automatically. If this does not happen within 10 seconds, the Immergas Eolo Star / Mini boiler switches on the "ignition block" (red indicator lamp on). To unlock, turn the main switch temporarily to the "Reset" position.
At initial ignition or after a long period of inactivity, it may be necessary to disable the ignition lock, as the lock may be activated due to the presence of air in the gas pipes. If the boiler locks up frequently, seek help from a qualified technician. Boiler blocking due to excess of its temperature - red indicator lamp flashes. During operation, a thermal overload occurs, the unit turns off. The reasons may be as follows: lack of water in the heating circuit; check that the pressure is between 1 and 1.2 bar; low circulation; check that no valves are closed in the heating circuit and that there are no bubbles in the system
air; the circulation pump is blocked; free him.
To start the Immergaz Nike Star / Mini boiler after blocking, set the main switch temporarily to the "Reset" position. Air pressure switch failure - red indicator light and yellow indicator light flash. This failure occurs if the air intake or exhaust pipes are blocked or the fan is not working. If normal conditions are restored, the boiler resumes operation without the need for a reset. Failure of the NTC sensor - the yellow indicator lamp flashes. During ignition, if the control unit detects a failure of the NTC sensor, the boiler will not start.
The Imergaz EOLO STAR 24 3 E boiler has been working for me for the third year, now sometimes such a problem arises - when the hot water is turned on, the pressure in the heating system drops and error 10 blinks. What can be seen?
Close the tap for filling the heating system tightly. Call the service, it is necessary to replace the heat exchanger (this can only be with the annual flushing of the heat exchanger).
Boiler Immergas Eolo Star 23KW. In operation for about 6 years. Recently, the pressure has dropped to 0, and often after using hot water for 10 minutes or more. It drops to zero several times a day. I checked the RB, the pressure turned out to be 0. I bought a pump with a pressure gauge, pumped up 1 bar. I filled the system by 1.2 bar, in the morning the error was 10, the pressure was 0. I have been experimenting for 3 days, looking for a problem. The make-up valve is turned on, it does not let through, the relief valve has been checked, the Mayevsky valve has been screwed on to check. I blocked the heating and hot water circuit from the boiler at night in order to understand where the leak is - in the system or in the device itself - overnight the pressure dropped from 1.2 to 0.5, error 10. So the problem is in the boiler itself. I checked the pressure in the expansion tank again - 1 bar. For the experiment added to 1.7. It didn't work, it crashes. A day later, that is, today, I bled all the air from the Republic of Belarus, again pumped it up to 1 bar. On the this moment, after 4 hours of observation, the pressure is holding, 1.8 on the gauge at the moment. Hope everything is back to normal. The question is, and yet, if the pressure drops again, where to look further, given that I have already checked everywhere. The last thought is that the problem may be in the breakdown of the heat exchanger wall, when water from the heating circuit seeps into the DHW circuit and, accordingly, the pressure drops when using DHW. What are the thoughts of who?
Clean the filter on the heating system. If cleaning the filter did not help, call the service and repair the pump.
I have an immergas boiler connected, 10 pressure 0.5 flashes on the display, I checked for leaks nowhere. I turn the pressure regulator, nothing. The pressure doesn't rise. What to do?
This means that the pressure in the cold water pipeline is low, and the heating system cannot be pumped. Release the pressure in the heating system and try to increase it back to 0.5 atm. Then if it worked out, then it is necessary to pump the heating system with the help of a pump. The pressure gauge may be broken, but if you drain the water from the heating system, and it shows the same pressure, then only a replacement.
When hot water is turned on, the Immergaz eolo mini boiler starts to vibrate, the higher the temperature, the greater the vibration, and when the water and heating are turned on at the same time, nothing works at all! What could be?
Please make it an annual Maintenance. Fan cleaning. If that doesn't help, then check the balance rings. Or replacing the entire fan. It is impossible in boilers (of any manufacturer) to turn on heating and hot water. Priority is always hot water.
We have a double-circuit gas boiler immergaz EOLO STAR 24 3 E installed. It goes out and turns on periodically only during the heating season, can it be somehow fixed?
If this happens once a day, then this is a self-testing system. It's okay, it should be so (in all boilers). If this happens more often, then there may be a problem with the control board.
Wall-mounted boiler Immergaz Eolo Mini, has been working for 3 years, there were no problems. Suddenly it stopped heating water, and the heating works as usual. What is the reason and how to fix it?
If the water from the hot tap runs cold, then it is the flow sensor to clean or change. And if it does not run from the crane, then this is very bad. You will most likely need to replace the heat exchanger.
The boiler is in operation for the second year, model Immergas EOLO star 24-3e. Last year (2012), the service center specialists carried out maintenance, which consisted in cleaning it from dust with a vacuum cleaner. In this (2013) did not cause. Problems have started recently. There is a room programmer. The unit heats up to 80 gr. turns off, the pump pumps water, and when the temperature drops to 40 gr. turns on again. Three batteries connected. But the furthest is cold. Blocked two close ones, earned a distant one. This was not the case before. Who can tell what's wrong?
The filter under the boiler or in the boiler is dirty (heating water) or the heat exchanger is clogged - i.e. a small flow of heating water, hence overheating.
I can’t remove code 05 in any way, the eolo star 24-3 e boiler does not turn on, what should I do?
Error 05: Faulty heating NTC sensor. Appears when the boiler is in any mode, including stand-by mode. The reason for the appearance is an open or short circuit in the NTC sensor circuit of the heating circuit. When error "05" appears: gas valve - closes, pump - runs out, fan - runs out. Restart - automatically after troubleshooting. Try replacing the sensor.
The gas boiler Immergaz Eolo Star was installed and connected, it has been operating for one year. Periodically, a single "biting" crack is heard from the boiler. I don't understand where it comes from and why. Secondly, the heating circuit is strangely warming. I set 50 degrees on the boiler, it starts to heat, the temperature reaches 50 in 30 seconds, the heating is turned off, then in 10 seconds the temperature becomes 40 degrees and after three minutes the heating of the heating circuit is turned on again. In fact, when 50 is set, it heats by 40. Can the circulation of the coolant in the boiler itself be disturbed?
The circulation is broken, the boiler boils. Either he or the system.
Wall-mounted double-circuit boiler Immergas Eolo Star 24-3e. Works 1 year (since 2011). The heating system (pipes, batteries) is new. After starting the heating this fall, I began to knock out the E27 error. I don’t catch a specific pattern - sometimes several times a day, but there seem to be days without this error. It seems that when it is colder outside and, accordingly, it works more intensively, it gives an error less often. I checked the valves for air release on the batteries and the connection of underfloor heating - I did not find airiness. What else can you do on your own? By the way, if you start hot water from the tap, it starts to heat the water, sometimes you hear some kind of gurgling / knocking, and stops giving error E27.
Error code 27 means insufficient circulation in the heating circuit, but this error usually crashes after opening the hot water tap in the bathroom (the distance from the boiler through the pipes is about 10-12m). At the same time, opening a hot tap in the kitchen (next to the boiler) does not cause such problems. I noticed a few more times that sometimes hot water does not run in the bathroom, and in order for it to go, you need to close the water and open it again.
I have a gas boiler Immergas EOLO MINI 24 connected, it’s the third year old, there are always some problems, this time the problem is this: the heating works fine, but when hot water is turned on, there is simply no hot water, it flows cold, and it starts to pick up temperature, and there is such a sound as if he is about to take off. Please help me troubleshoot.
The DHW flow sensor is faulty (most likely the float is jammed from dirt). You can wash or replace if that doesn't help.
We have an Immergas MINI Nike 24 3 E wall-mounted boiler installed. It worked for two winters without any problems, only small pops are heard when ignited. But suddenly, when you turn on the hot water, he goes crazy and starts to pick up the temperature sharply. All three torches on the display are lit. The numbers run for a hundred, crackling and overheating are heard, error E27 appears. And if you do not turn on the water again, it will blink for a long time. How to fix it?
You have very bad traction, because of this and pops. If overheating occurs after turning off the hot water, then you need to clean the flow switch. If during use it knocks out, then it looks like the boiler is clogged with scale. In any case, first deal with smoke removal and air intake - this is primary (by the way, because of this, there may well be a problem with hot water, especially if the heat exchanger cells are clogged with soot).
We did the installation and connection of the Immergas EOLO Star 23kw boiler. It periodically starts to crack and the temperature jumps on the display, error 27 appeared a couple of times, I restart it, and it starts working again. What could it be, and how to deal with it?
It looks like the heat exchanger is clogged. The heating circuit is practically not cleaned. Check the filter at the inlet, possibly a poor-quality heating system.
Tell me, what could be the problem, the boiler stopped heating more than 32 degrees. Model Immergas mini 28 kw, new 2-3 months as installed.
Little flame. Low gas pressure at the inlet, the grid on the gas valve is clogged. Lack of gas modulation. valve (it is necessary to look at the currents on the coils). If the currents are bol. 200mA, which means that the board is controlled. Check valve outlet pressure.
Gas boiler Imergaz NIKE Star 23kW. Works for the eighth year. Of the breakdowns, for 6 years I didn’t look into it at all. In the seventh year, the valve was replaced to fill the system (it began to leak), and this year it constantly gives error 01 "Locking due to lack of ignition." According to the instructions - press "reset". I do. It behaves unpredictably - it may start working, or it may continue to flash 01 again. For a day - 20 times. What to do?
First of all, it was necessary to serve on time. You need to call a good service guy. In your case 1. there may be no ionization current on the central electrode (the current is very small and not every device can be measured). 2 bad board. 3 The gas valve is not working properly.
Error 28 flashes in the boiler. We checked the entire system, there is no leak anywhere. And he still turns off. When I restart it on a new one, it seems to work, but not for long. And again error 28.
Error 28 - leak in the DHW system. You have a hot water faucet leaking somewhere. The system sees that the boiler is working for heating, and the temperature in the hot water is also growing, although it should be constant. Eliminate leak.
I have connected the Immergas EOLO Star 24 kw boiler after installation. 3 years. The problem is this - yesterday morning they turned off the light, the unit stopped working, and I turned it off from the network. Half an hour later, the light was turned on, I turned it on, and it started flashing and gave an E10 error (insufficient pressure in the system). I dialed the system, it seemed to start working, then after a few hours again the E10 error. I again dialed the system to almost 2. The next morning, the same thing. I checked every pipe, climbed everything, I thought there was a leak somewhere, but no, everything is fine. Tell me what to do?
In the boiler, pressure can drop only in two cases: a problem in the expander (native or additional - not so important) - most often, or a breakdown in the heat exchanger - one case per million, provided that the heating system is 100% tight.
The apartment has a gas wall-mounted boiler Immergaz EOLO STAR. What does error code 03 mean? First turned off, burned 11, and then 03?
Error 03 - the fan is defective. 11 - "no exhaust" no pressure of combustion products. I solved the problem this way: first I removed the casing and opened the chamber, there is an engine that draws air from the combustion chamber, 15x15 cm in size in the form of a snail, unscrewed it with 3 screws, cleaned the blades from stubborn dust on the blades with a hard brush, the main thing is not to knock down the balance (on some blades have staples). Bearings lubricated and put in place. I include - the same problem. Moreover, I began to clean, because 1 day before the error 11 was issued, I had extra noise from this engine. After cleaning it disappeared. I looked in the instructions indicates "combustion products pressure switch" this relay is located in my upper right. A capillary tube is connected to it. The principle of the relay is as follows: through the tube, the one that fits in the fan chamber, when this fan is turned on, a small air pressure is supplied, which closes the relay. A closed relay sends a signal to the control unit, and the burner ignites (well, at the same time, a number of other conditions are probably met, but for me it was not important). In general, the problem is that the fan motor was running, but the burner did not ignite. I took this transparent capillary tube out of the fan chamber and blew into it (i.e. into the sensor). The result - the relay closed, the burner caught fire. As a result, I realized that either the sensor was reconfigured to a higher air pressure, or dirt in the capillary tubes, or in a fitting attached to the fan chamber. He pulled out the fitting (from which he pulled out the drip tube on the fan chamber), cleaned it and filed at an angle the inner tube, which is located in the fan chamber, for better air passage. Put everything in place, plugged it in. And the boiler worked as before. But after a few hours I saw the same picture again - error 11. Then I turned off the "combustion products pressure switch" (by the way, after that I got error 03 on fire, so it is likely that there is a bad contact, and this sensor is located in a place where it is very warm, I would say heat. In general, I tore off some kind of yellow plug on this relay, I saw two screws, tried to twist them and realized that one of them is responsible for adjusting the air flow at which the relay is triggered. Adjusted to the smallest flow. I connected everything back to the boiler, started it while it was working.
The Immergas Nike star boiler has already worked for 10 years. It was different, but I encountered such a failure for the first time - when the heating (hot water) is turned on, it goes into blocking (the yellow and red LEDs "Not enough water in the heating system" flash alternately), while on the pressure gauge 1.2, it raised to three bar, the picture does not is changing. When using hot water, the boiler immediately goes into blocking, and when using heating, the pump works for 1-2 seconds, the relay is activated (which one has not yet been determined). The candle does not work, and the boiler goes into blocking. Manipulating the RESET position does not give the proper result. Further - after the passage of water through the hot water supply for 10-15 minutes, it started up.
Check the pressure sensor of the heating system. Maybe covered in dirt.
A gas boiler Imergaz Nike star 24 kw was installed, the water pressure sensor failed, the work was restored with a jumper. Is it possible to operate like this or is it better to install a new sensor?
In spite of decent quality boilers from modern manufacturers, during long-term operation they may fail and then repair of gas boilers may be required. Undoubtedly, it is best in this case to seek help from specialized specialists or use a service guarantee. But if this possibility is excluded, some problems can be fixed by hand.
It is about how to do it safely and at minimal cost, as well as what nuances to pay attention to Special attention and will be discussed here.
Causes of breakdowns of gas boilers
Autonomous gas heating provides people with comfort and warmth. The “heart” of the entire system can be safely called the boiler, malfunctions in which can adversely affect the operation of the equipment or suspend its operation completely.
Gas boilers can fail for several reasons:
- settings failure;
- damage to shutoff valves;
- the pump does not work;
- poor performance of the hood;
- clogging of the chimney, resulting in the operation of a special draft sensor;
- violation of the rules of operation and safety;
- low quality components;
- power failure due to a drop in gas pressure;
- mechanical damage, etc.
Also, repair of gas boilers is required in case of defects in the controls and protective systems of the unit.
Features of breakdowns
Whatever the problems are: small or costly, they must be eliminated efficiently and promptly, because violations in the work gas equipment can cause not only accidents, but also explosions.
Experts classify breakdowns of gas units as follows:
- Explicit or hidden - depends on the ease of detection of the defect.
- Independent and dependent, that is, entailing a number of further problems.
- Sudden or gradual, that is, those that appeared after long-term operation or manifested themselves without apparent reason, suddenly.
- Final or intermittent.
If the user noticed clear signs breakdowns: for example, water is heated for too long, some kind of small detail or atypical sounds appeared, then you should not wait for the unit to stop working completely, it is better to repair it as soon as possible, without taking it to the extreme.
According to statistics, about 90% of boiler malfunctions can be determined by visual inspection heating system. Most defects are eliminated without much difficulty, only a few of them require intervention in a service center.
Testing equipment and its in-depth diagnostics is considered a task that only certified specialists are able to carry out. They will also help to analyze the economic feasibility of repair and restoration work and provide repairs and regular maintenance gas boilers. Situations are quite common when the replacement of parts and repair of the unit are almost comparable in cost to the purchase of a new boiler. Most often this applies to cheap, low-power or not very high-quality wall-mounted devices.
The purchase of new, more economical equipment will also be justified in the event of obsolescence of the boiler.
Classification of repair work
It is very important to make scheduled inspections and timely maintenance of the gas heating system on time, which minimizes possible costs and ensures the long-term operation of the equipment. Maintenance provided by the manufacturer within a certain period of time, as opposed to repair work, is produced for normally functioning heating equipment. Sometimes small parts can be replaced.
If it came to repair, then the following types are distinguished:
- Capital, entailing significant cash costs and a large amount of work. It provides for the replacement of obsolete and faulty equipment.
- Current, the purpose of which is to maintain the efficiency of equipment and eliminate possible technical defects.
- Preventive and planned maintenance of boilers, which is carried out in a clear deadlines(this applies to system parts that, according to the documents, should fail earlier than other elements due to a limited resource of use).
- Restorative repair of gas boilers, in which the system is washed, and the electrodes, heat exchanger, etc. are cleaned.
Self-repair of equipment
The purchase of any heating boiler is accompanied by the issuance of instructions and technical documentation, without which you can not do in the case of the repair of equipment. The instructions, as a rule, always provide a list of the most common problems and methods for resolving them.
Modern technology is equipped with special sensors and elements that control the correct operation. That is why, in the vast majority of cases, protective systems work on time, which prevents a lot of problems.
Experts say that do-it-yourself repair of a gas boiler is justified only in the cases described in the documents accompanying the equipment, that is, if the defect is clearly marked and does not require complex manipulations.
All other breakdown options require a theoretical base, practical skills, and often the use of high-tech specialized equipment.
Important: breakdowns of gas boilers cannot be treated negligently, this can lead to a threat to the life of the user due to exhaust carbon monoxide or fire!
Troubleshooting
- If you smell burning or gas, you should immediately open the doors and windows. Most likely, the combustion sensor failed, which reacted to the emergency thermostat signal. It is necessary to turn off the boiler, allow it to cool completely, then check the quality of the draft and try to start the unit. If nothing works out, it’s not worth the risk, it’s better to immediately call the gas workers.
- If the problem is in a contaminated heat exchanger, then the problem will make itself felt by overheating the boiler. In this case, the heat exchanger is cleaned and the operation of the equipment is tested again. If the heating of the boiler remains at the same level, then the automation is probably not functioning correctly.
- A clogged column manifests itself by the attenuation of the flame. You can clean it with your own hands, according to the instructions.
- A clogged fuel supply pipe is also often clogged and needs to be cleaned. To do this, it is disconnected, washed, dried and attached to the boiler.
- The draft test is carried out only if there is absolute certainty that there is no smell of gas in the house. A strip of newspaper brought to the chimney will serve as a kind of “litmus test”: if there is no draft, the paper will remain motionless. This problem requires an immediate call to a professional!
- If the gas boiler is leaking, i.e. fluid has escaped from the safety check valve, this indicates an excess of pressure in the system. The defect is eliminated by adjusting the water supply. Also, the boiler may leak due to depressurization of the seams. In this case, the help of gas specialists is needed.
- If excessive condensation has become noticeable, then it is time to insulate the boiler or equip the room where it is located with an additional source of ventilation.
- The constant excessive hum of the boiler indicates poor sound insulation, and the periodic one indicates contamination of the primary heat exchanger.
- Fuel pumps most often do not work due to damage to the cable, which is quite simple to replace with a new one.
- Maintenance of gas boilers involves special attention to their prevention, and also guarantees the departure of a specialist in case of any contentious issues.
Questions about the operation of boilers Immergaz
Question: A gas boiler immergaz eolo star 24 3 e was installed, it gave an error 11, what should I do?
Answer: Your pressure in the system has dropped below 0.8 kg, you need to increase the pressure with the make-up to 1.2 kg and reset the "RESET" error, then the boiler should start. Possibly insufficient flue duct. Check smoke detector and fan. Maybe there is dirt in the pipe.
Question: We connected the wall-mounted boiler EOLO MYTHOS 24 2E IMMERGAS, installed it myself, connected everything according to the instructions: voltage stabilizer, brown wire per phase, grounding, everything is as it should be! During the initial start-up, the boiler started up, but a day later it gave me error 01 (ignition block), reset the error with the "RESET" button, and this is repeated several times a day. I don't know what the problem is, can someone
suggest.
Answer: Error 01 - no gas. When it lights up, it is necessary to check the presence of gas in the stove. If it is not there, then contact Gorgaz. If there is, then to the service.
Question: when the Imergaz boiler is turned on, error 10 is knocked out, what should I do?
Answer: The pressure in the heating system has dropped. You need to fill it out.
Question: I have an Imergaz EOLO Star 24 gas boiler installed and connected. Recently, error 11 has been popping up all the time. I cleaned everything, coaxial pipe, fan, chimney, etc. And the error doesn't go away. On the street strong wind the house is getting colder.
When hot water is turned on, after a few seconds the boiler starts to crackle and the water temperature quickly starts to rise on the indicator. If you turn off the hot water supply, then the set of water is somehow very short. I would say that the boiler does not get right amount cold water into the tank and starts heating itself. What to do in this case?
Answer: Clean the DHW filter (flask).
Question: The situation is as follows, we bought a house, 130 square meters, installed wall-mounted boiler immergas. At the beginning of the repair work, everything was fine, he worked for himself and worked. Once I entered the house, I found that the batteries were not hot, a little warm, I looked at the boiler, but the red light was constantly on, as a result I got through to the master, he said to do a reset (RESET), did it, the boiler worked, the next day the situation
repeated! And in our city, no one has ever come across such boilers, and everyone advises changing it! I don’t know what to do, everything is too expensive to repair.
Answer: This comes from the freezing of the exhaust pipe for the removal of burnt gases. If you look at the boiler from above, then near the outlet of the exhaust pipe from the boiler there are hatches on the left and on the right, open one of them and the problem is solved.
Question: We open the make-up of the gas boiler Immergaz EOLO STAR 24 3e and you can’t hear how it works, and the pressure is at 0.8! What to do?
Answer: The only problem is the pressure in the DHW system, it is less than in the heating system. It is necessary to increase the pressure using a pump or buy a pump for the DHW system.
Question: We did the installation and connected the wall-mounted boiler Immergaz Nike star 23 kw in operation for about 4 years. It's our second year. will be the third winter and it seems that the overall temperature is lower. Should be warmer. When ignited, it starts to click - 5-6 seconds. Then it works for 40 seconds, well, up to a minute and goes out. What could it be?
Answer: Check the return filter, if installed.
Question: The house has a gas boiler immergaz eolo star 24kv house 160kv. What is better a temperature sensor or a boiler for the temperature of the heating circuit?
Answer: Install a room thermostat.
Question: Advise, I want to install an immergas victrics 26 2i boiler, a house of 100 m2, panel vulture, bottled gas, they say an economical boiler, because. the lower limit of operation is 5 kW, I understand that large radiators will have to be installed. there is no use of a warm floor, I want to use it in 40/50 mode. It is clear that it is a little expensive, I am ready to spend money, is it a good model and is it worth installing?
Answer: A condensing boiler is beneficial in low-temperature conditions. You really have to double the power of the radiators (approximately), spending about 60-70% on this Money, optional. A condensing boiler saves about 25-30% of gas.
But can you recoup it in the end:
The cost of boilers is two times different.
- the cost of organizing a low-temperature regime.
- more expensive spare parts (differ by 2-3 times, some and 4 times).
- more expensive service maintenance annual.
Boiler Victrix 26 2i - can modulate up to 3 kW.
Question: tell me what is better to transfer the boiler to a lower power or install an external temperature sensor, otherwise it often turns on, it works for a couple of minutes.
Answer: You have a small area of the room: Be sure to buy a room thermostat. When installing it, it is recommended to set the heating temperature to 70 degrees on the boiler.
Question: We connected the boiler Imergaz eolo star 24, but the water pressure drops and displays error 10, when I add pressure, the boiler starts and works after a while it turns off again. Is that the expansion tank covered up?
Answer: No, not expansion tank. There may be problems in the heating system or in the boiler (heat exchanger), etc.
Question: When DHW is turned on, hot and cold water flows. The E-27 code is displayed, but the DHW pressure is good, what could it be?
Answer: Setting up the boiler, if it started immediately, after the first start. So whatever - the gas block does not modulate or is clogged with chips in the pipe, flow switch, etc.
Question: tell me, did you install the Immergaz boiler, does it heat the water well, but does the heating not heat at all?
Answer: 1. Please turn on the winter mode (snowman). Then the boiler will start to work in heating mode.
2. Look at the temperature of the coolant (water) in the heating system (buttons with a picture - radiator). Maybe simply, there is no need to work in heating mode - summer, warm.
3. If you are using room thermostat, then look at what temperature is set on it. Maybe simply, there is no need to work in heating mode - summer, warm.
4. If the boiler is out of order, it must go into emergency mode and indicate the error code on the display. Follow the instructions in the user manual or call the service.
Question: Yesterday we connected the Immergas Eolo Star boiler. During the briefing, they explained that during the summer operation of the boiler, you can use either warm or cold water. Those. cannot be mixed. Explain why?
Answer: You can set any comfortable temperature for hot water preparation. And in any mode (winter, summer). They simply recommend setting a comfortable temperature for hot water, so that the prepared hot water is mixed with cold water as little as possible. This is to save gas. For example, a comfortable water temperature is 42-43 C, then set 45-46C, not 55 C.
Question: We have connected a gas boiler Immergaz. Tell me, what is the right temperature to set in the summer?
Answer: DHW temperature. - In summer, turn on the summer mode (umbrella) and set yourself a comfortable temperature of hot water, as in other things in winter. Heating temperature - If it suddenly becomes cold and there is a need for heating, then turn on winter mode(snowman). And also set any temperature of the coolant. It is best, of course, to use a room thermostat.
Question: I have an Imergaz eolo star 24 3e boiler installed, the problem is that when I turn on hot water, the boiler makes a wheezing sound and wheezes until I turn off the water, what can it be?
Answer: It is necessary to make maintenance of the boiler: the heat exchanger is clogged, it is necessary to flush it. Clean the fan, when the boiler is turned on in the DHW mode, the boiler goes to maximum work, and the fan cannot cope due to dust (dirt), noise and vibration begin.
Question: I have an IMMERGAS NIKE STAR gas boiler. In operation for the eighth month. Summer mode is now enabled. There is no hot water. Displays error code 10. Water pressure is normal. But if you switch to winter mode, hot water appears. How to find out the reason?
Answer: Error 10 - no pressure in the heating system. Options: a problem with the heat exchanger, the make-up tap does not hold.
Question: I installed a new Immergaz turbocharged boiler, 01 flashes. I rebooted - it doesn’t help, I called a specialist and replaced it with another new board, it still gives a signal 01. What should I do?
Answer: 1. Check whether there is gas, in general, in the house. Turn on gas stove, if there is no gas there, then call the gas utility. If there is gas in the stove, then open gas cock sometimes they forget to open it.
Call master:
Check gas valve setting at minimum.
- check the gas valve for modulation (drive it)
- it happens that the valve sticks (knock on it, and it will start working without problems), this can only be when the boiler is first put into operation. if problems are visible, then replace it.
Check the grounding, there are cases under certain conditions, the flame ionization sensor does not work and gives error 01.
Question: Six months since the Immergaz Eolo mini boiler was connected. The problem is that the ignition did not work periodically, mainly for hot water, while at first fault code 04 was displayed. After prevention, it worked perfectly for half a day, after that the ignition disappeared altogether, neither hot water nor heating works, the display does not give a fault code. What is the reason?
Answer: The problem is in the control board, or in the ignition electrode (which is very rare).
Question: Tell me, who knows if this problem is eliminated at all. I have an Immergaz boiler connected, almost new, only 1 year old. There is no constant temperature in the DHW system, no matter what temperature it is unpleasant to wash, there is either hot or cold water, what can be done? And so everything works properly, no errors are displayed.
Answer: It shouldn't be. The boiler has a modulation function, and the boiler must instantly respond to the flow of water and its temperature. You must also keep set temperature. This may be in the wrong setting of the boiler or it was not set up at all. It is necessary to know whether it was from the very beginning (the first launch) or happened in the process.
Question: I have an imergaz EOLO STAR 24 3 E boiler that has been operating for the third year now sometimes such a problem occurs when the hot water is turned on, the pressure in the heating system drops and error 10 blinks. what can I see?
Answer: Close the tap for feeding the heating system tightly. Call the service, it is necessary to replace the heat exchanger (this can only be with the annual flushing of the heat exchanger).
Question: Boiler Immergas Eolo Star 23KW. The boiler is about 6 years old, recently the pressure has dropped to 0, and often after using hot water for 10 minutes or more. It drops to zero several times a day. I checked the RB, the pressure turned out to be 0. I bought a pump with a pressure gauge, pumped up 1 bar. I filled the system by 1.2 bar, in the morning the error was 10, the pressure was 0. I have been experimenting for 3 days, looking for a problem.
The make-up valve is turned on, it does not let through, the relief valve has been checked, the Mayevsky valve has been screwed on to check. I blocked the heating and hot water circuit from the boiler at night in order to understand where the leak is - in the system or in the boiler itself - during the night the pressure dropped from 1.2 to 0.5, error 10. So the problem is in the boiler itself. I checked the pressure in the RB again, 1 bar. For the experiment added to 1.7.
It didn't work, it crashes. A day later, that is, today, I bled all the air from the Republic of Belarus, again pumped it up to 1 bar. At the moment, after 4 hours of observation, the pressure is holding, 1.8 on the gauge at the moment. Hope everything is back to normal. The question is, and yet, if the pressure drops again, where to look further, given that I have already checked everywhere. The last thought is that the problem may be in the breakdown of the heat exchanger wall, when water from the heating circuit seeps into the DHW circuit and, accordingly, the pressure drops when using DHW. What are the thoughts of who?
Answer: Clean the filter on the heating system. If cleaning the filter did not help, call the service and repair the pump.
Question: I have an immergas boiler connected, 10 pressure 0.5 flashes on the display, I checked for leaks anywhere. I turn the pressure regulator, nothing. pressure does not rise. What to do?
Answer: This means that the pressure in the cold water pipeline is low, and the heating system cannot be pumped. Release the pressure in the heating system and try to increase it back to 0.5 atm. Then if it worked out, then it is necessary to pump the heating system with the help of a pump. The pressure gauge may be broken, but if you drain the water from the heating system, it will show the same pressure. Replacement.
Question: when hot water is turned on, the Immergas eolo mini boiler starts to vibrate, the higher the temperature, the greater the vibration, and when the water and heating are turned on at the same time, nothing works at all! what could be?
Answer: Please do the annual maintenance. Fan cleaning. If that doesn't help, then check the balance rings. Or replacing the entire fan. It is impossible in boilers (of any manufacturer) to turn on heating and hot water at the same time. Priority is always hot water.

Boiler "Immergaz" out of order? Is the job blocked and the display shows errors? Don't worry, this is how the security system reports a problem. What to do? Look at the instructions and find out the designation of the code. If the instruction is lost or you do not understand the technical language, then refer to our publication. We have described the errors of Immergaz boilers in an accessible way.
Operation and installation of Immergas boilers
The Italian manufacturer of heating equipment "Immergaz" is focused on all segments of the population. From a wide range, you can choose Economy class models or high-tech devices at a high price.
The equipment is adapted for operation with unstable pressure in the gas line - up to 3 mbar. The design is equipped with the following components and parts:
- Gas burner with electric ignition;
- Circulation pump from the company "Grandfos". The technique has proven itself to be reliable and quiet;
- Bypass with regulation system protects the heat exchanger from overheating;
- The reed sensor measures the temperature of the coolant flow;
- Antifreeze mode. If the temperature drops to 4 degrees, the boiler starts automatically. After that, a constant heating of 40 degrees is maintained;
- Outside thermostat available. It can be connected at will.
The range includes conventional convection models as well as condensing ones. The latter are distinguished by an increased efficiency of more than 100%. By design, there are single-circuit and double-circuit units. Combustion chambers - open and closed type.
Anti-scale protection is provided. When heating is completed, the pump does not stop. For about 3 more minutes it pumps cold water through the system, removing the heat load.
Errors and malfunctions
Technology is not immune to breakdowns. If you saw an error code, you can find its meaning and solutions in the table below. First of all, it is recommended to restart the boiler in order to exclude a system failure. If the symbols light up again, proceed with the repair.

Problems "Immergaz" with automatic unlocking
As soon as you eliminate the cause of the malfunction, the board will automatically resume operation and heating.
What codes are found:
- b 18 - violation of the heating of the supply circuit (over 95 ° C). Eliminate the causes of poor circulation of the coolant (blockage of filters, heat exchanger, pump blockage);
- b 19 - the heating level on the return line has exceeded 90 ° C. See solution for b 18;
- b 24/b 30 - supply and return thermistors give different readings. The difference is 10°C. Heat exchanger diagnostics. Descaling;
- b 25 - rapid increase in the degree on the feed line. Feed the circuit with water;
- b 26 - pressure decreased. Measure readings, add coolant to the circuit, adjust the pump operation;
- b 28/b 29 - the fan does not work. Replace the assembly in case of breakage;
- b 33/b 38 - short circuit, breakage of the DHW thermistor. Connect a new part;
- b 65 - the fan does not start for a long time. Diagnostics and replacement.
Another common malfunction is a yellow uneven flame. In this case, the burner should be cleaned of soot and dust. Also remove dirt from the chimney shaft - it disrupts draft.
Not all models are equipped with a display. Some issue a breakdown code by glowing indicators. For example, Immergas Nike Star/Mini.
If you are unable to fix the breakdown yourself and the symbols are repeatedly displayed on the screen, it is better to call the wizard.

Features of boilers Immergaz
Home distinctive feature gas boilers Immergas Eolo Star and Immergas Nike Star is the following:
Grundfos pump Most Common Error Codes and Troubleshooting
Let's try to figure out what the Immergaz gas boiler error codes mean. The most common error 01 is the blocking of the ignition. Let's consider each error in more detail.
01
Ignition lock. The boiler is designed so that the inclusion occurs automatically. If after ten seconds the burner has not been ignited, a lockout is performed. To remove it, click on reset.
If the boiler turns on after a long period of inactivity, it will be necessary to remove the blockage, since air has accumulated in the gas line. If the unit turns on frequently, contact your qualified help to a specialist.
02
Error 02 - the safety thermostat is activated, overheating has occurred, the flame control is faulty. If during normal functioning device temperature starts to rise, the protective function is activated. Wait until the temperature drops to required level, then press the restart key. If this problem occurs frequently, seek help from a specialist.
03
Error 03 is displayed when the smoke thermostat is activated. That is, a fan malfunction, to solve the problem, remove the case. Then open the chamber, it contains an engine that draws air from the combustion chamber. Open it by unscrewing the screws, clean its blades from accumulated dirt, this can be done with a brush. Treat the bearings with grease and install everything back.
04
Error 04 - high resistance of electromechanical contacts. The contact is blocked, the cause may be the failure of the protective thermostat or the sensor of the minimum allowable water pressure. Turn off the device, and after a couple of minutes, try restarting, or try closing the limit thermostat contact.
Water pressure sensor
If this does not work, close the minimum pressure contacts. Test the contact at the smoke exhaust pressure switch in the same way, after turning on the fan. If you find where the breakdown is, replace the element. If this does not work, you need a repair performed by a qualified specialist and diagnostics of the board.
06
Error 06 - there was a breakdown of the NTC sensor in the hot water system. For identification and repair, you must contact the service center.
10
Error 10 - low pressure in the system. Error e10 occurs when the pressure drops in the system, when it is less than 0.9 bar. First, try restarting, if the error remains, you need to check the following.
The cause may be a heat exchanger leak, check it, if a leak is found, fix it. To eliminate it, use the recharge lever, it looks like a screw, turn it counterclockwise, by this action the water from the water supply will flow into the heating, follow the pressure values, when the number is 1.3, close the valve.
11
Error 11. Smoke pressure thermostat operation. When the chimney does not work well, the boiler is blocked, after half an hour it restarts if the draft has become sufficient. If more than three shutdowns occur in a row, the display will turn red with an error code.
Smoke pressure switch
Press restart to unlock the boiler. In the instructions, the manufacturer recommends contacting a service center, however, first you can check the chimney draft and clean it.
27
Error 27. This error indicates insufficient circulation in the heating system. The boiler starts to overheat, the reasons for overheating may be the following: air in the heating pipes, the taps are closed. It is also possible that there was a blockage circulation pump, unlock it. The cause may be clogged filters, check and clean. Check the heat exchanger for deposits.
Removal of air from the heating system
28
Error 28 indicates a leak in the water supply circuit, that is, the device heats the heating circuit, and the temperature in the water supply also increases, at a time when it should be unchanged. Check all the faucets in the house for leaks, also check that the taps are closed.
Other malfunctions
To the most frequent malfunctions These devices include the following:
