Baxi boilers - great choice for autonomous heating systems. They are distinguished by increased comfort, a variety of automation and ease of use. Any additional equipment can be connected to the boiler. An example is programmers, or room thermostats for Baxi gas boilers.
Advantages of Baxi boilers
Main 24 Fi 24 kW
The advantages of Baxi gas boilers are obvious, and the possibilities of such units are multifaceted. We list only the main advantages of such boiler equipment:
- Ability to connect additional elements, sensors and automation systems.
- The ability to automatically change the temperature regimes depending on the temperature delta in the street and at home.
- Economy of operation.
- "Smart" self-diagnostic systems.
- The possibility of using the unit not only in traditional heating networks, but also in the "warm floor" system.
Additional accessories
Note! Most of the models in basic configuration equipped with built-in electronics, control systems and various sensors. Installing optional accessories makes operation easier, more convenient and more efficient.
Optional accessories open up a whole range of possibilities for equipment control:
- Temperature control by time of day and season.
- Setting the temperature in different rooms.
- Work in economy mode.
All this reduces gas consumption, which means it makes the system energy efficient and its operation economical. Paradoxically, most consumers refuse to install additional equipment for reasons of economy. Of course, the installation of these devices will increase the cost of the system. But on the other hand, it will save on heating bills.
The installation of additional devices pays off already in the first two heating seasons. So gas accessories Baxi boilers- this is not only additional comfort, but also significant fuel savings.
Variety of accessories
accessories and additional equipment there are a lot of Baxi boilers on the market. We list the main ones:
Clear display
- Digital timer. The device allows you to program the work engineering networks for a certain period. When using it, the boiler will turn on / off at the time specified by the consumer. You can use this device not only for programming heating, but also for boilers.
- Room thermostat, or thermostat. This device maintains the set temperature and allows you to control the microclimate. The boiler equipped with a programmer will work in automatic mode. In this case, no intervention on the part of the consumer in the operation of the unit is required.
- Sensor outdoor temperature. To maintain heat in the house, it is necessary to take into account the temperature of the street air. The power with which the boiler must operate directly depends on the delta (difference) of room and street temperatures. The outdoor temperature sensor allows you to maintain a constant mode, no matter what the weather is outside the window.
- Sensor room temperature. It is recommended to install it together with the above device. Both devices, working in pairs, guarantee the so-called self-adaptation of the boiler.
- Digital control panel. This is a real highlight. You can install it in a convenient place. With its help, not only control, but also system diagnostics takes place. This device can be used with or without a programmer.
These are not all accessories that can be connected to room gas boilers Baxi. In more detail, you should dwell on the most common device - a thermostat, or temperature controller.
Why do you need a thermostat?
Suitable thermostat
In fact, the thermostat is a device that allows you to regulate the temperature in the room in automatic mode. It can be argued that it is easy to regulate the operating modes of the boiler without automation, that is, manually. At the same time, the thermostat becomes an unnecessary luxury, entailing extra costs funds. Consider the pros and cons of installing such accessories.
During the operation of gas boilers, the microclimate in the premises is regulated by changing the temperature of the coolant. When the set value is reached, the boiler turns off, and when it decreases, it turns on again. When changing outside temperatures, it is necessary to change the parameters of the heating system, and this must be done manually. As a result of interference with the operation of boiler equipment, they are required throughout the entire heating season.
The time and attention taken by the boiler when manually adjusting its operation are not the most important problems. In this mode, frequent starts / shutdowns of the boiler occur, which does not have the best effect on its performance, and on the reliability of the system as a whole. There is one more problem. When the boiler is in constant on / off mode circulation pump continues to function. Being an energy consumer, it increases the cost of electricity, which increases the financial costs of heating. Not to mention the negative impact on the operation of the system.
As you can see manual control for high-tech gas boiler- not the most the best option. Now consider what the thermostat can change. The device has room temperature sensors that monitor the temperature not of the water in the system, but of the air in the premises. As a result, the boiler is turned on / off when there is a deviation from the set temperature regime, and not when the water heating decreases.
The frequency of starts/shutdowns is significantly reduced. When programming the device, you can set the optimal threshold for triggering such a sensor. In addition, you can set the delay time for turning on or off the boiler when the sensors are triggered. This will minimize the likelihood of starting the heater in case of a short-term decrease in temperature, for example, as a result of a draft.
Model TAM011MI Seitron
As practice shows, installing a programmer saves 25-30% of energy. The device does not allow excessive fuel consumption. When the boiler is turned off, the circulation pump is automatically turned off, which saves energy. All this speaks in favor of installing room thermostats.
The payback of such accessories is beyond doubt. On the market are various models thermostats, differing not only in technical parameters, but also in price. Finding the right accessory is not difficult. Examples include TAM0 11MI, Menred RTC 70, Raychem TE Basic, DEVIreg Touch, Nest, domestic MCS 300, etc. temperature controllers.
Central thermostat
This type of programmer is installed in the house and connected to the heater either by wires or via wireless networks. The latter are more expensive, but more convenient and efficient.
The main advantage of wireless thermostats is the ability to install them anywhere. At the same time, they do not violate the interior, and their installation does not require any complex fixtures or destruction. building structures. The case is fastened with self-tapping screws, after which all the necessary electronics are connected, and the necessary parameters are set. This device can be operated remotely. Its operation is allowed not only with gas, but also with solid fuel boilers.
Installation rules
Room regulator
Installation of central thermostats is simple. But it is necessary to adhere to several rules in order not to violate the efficiency of the system in the future:
- The regulator is mounted in such a way as to ensure free air flow.
- Nearby there should be no household electrical appliances, lamps, touch switches, additional heaters, etc.
- The thermostat must be freely accessible.
Additional options
The main function of thermostats is temperature control. For greater efficiency, the devices have additional options:
- The ability to turn off the heating for several hours, for example, in the long-term absence of people in the house.
- Possibility of temporary change of all programmed modes of operation.
- The ability to change the temperature regime on certain days.
The benefits of installing a thermostat are obvious. The payback of devices is also not in doubt. Nevertheless, the desire to save on the installation of such a useful device is still strong. This often encourages homemade "homemade" to do everything with their own hands. And not just to install the device yourself, but also to assemble it from improvised materials.
Installation process
Theoretically, it is possible to make a thermostat with your own hands. This will require a thermistor that reduces resistance when heated. Then another resistor is connected to the network, with the help of which temperature programming will be carried out. The 2I-NOT element will operate in inverter mode, and voltage will be supplied to it. A capacitor is connected to it and to the trigger. To control the relay, the galvanic isolation on the triac is enhanced. The device can be made both on a mole rat and on a printed circuit board.
Using such a simple circuit, you can assemble a thermostat for almost any boiler. But is it worth interfering with the operation of high-tech equipment? It's up to the owner of the house to decide. Experts do not advise experimenting with homemade devices, especially since on the market you can pick up accessories for any boiler.
In order not to make a mistake in choosing a programmer and purchase suitable model enough to adhere simple tips specialists:
Features of choice
- It is desirable that the boiler and its accessories are made by the same manufacturer.
- powerful models heating equipment can be operated with any version of programmers.
- Before buying, it is worth calculating the necessary technical specifications Otherwise, equipment downtime is likely.
- If it is necessary to install a device of a high power class, it may be necessary to change the wiring, so it is better to consult a specialist.
Any doubts left? You can always buy a cheap model with minimum set functions and options. Its operation will clearly show how expedient the installation of expensive additional accessories is.
Conclusion
Additional accessories for Baxi gas boilers are not a luxury, but an opportunity to make the heating system energy efficient in the full sense of the word. Installing only one room thermostat can reduce heating costs by about 25-30%.
Energy prices are rising regularly, gas is no exception. Therefore, owners of wall-mounted gas boilers are increasingly thinking about savings. In general, modern gas boilers are quite economical and heating an apartment or country house quite cheap compared to similar services commercial organizations. In this article, we will consider what factors affect the efficiency of a gas boiler using the example of BAXI.
Heat carrier temperature
Proper regulation of the coolant temperature will directly affect gas savings. In the basic configuration, boilers are mostly not equipped with an outdoor temperature sensor, therefore, throughout the heating season, the user must independently choose the temperature of the coolant depending on weather changes: either increase or decrease.
This is not very convenient, especially since Baksi boilers allow you to connect a sensor as an option. Even in this case, the term weather-dependent automation can be used. Then, the regulation will take place automatically depending on the climate curve selected in the boiler settings, and the boiler will consume less energy to useless heating, which will lead to gas savings.
Boiler clocking
Clocking is the frequency of turning on equipment for heating the coolant. If baxi are not connected to the boiler external devices control, the interval between switching on the boiler can be set to a maximum of 10 minutes (default 3 minutes).
For example, for the BAXI ECO FOUR boiler, this is the configuration parameter F11 Burner waiting time between two ignitions.
Frequent switching on is not economical - the more time the boiler will work continuously, the better. At one of the forums, the user expressed concern about the long-term continuous operation of the boiler, but on the contrary, this means that a mode has been established in which the heat losses of the room are continuously compensated while maintaining optimal temperature coolant.
This problem is most relevant for owners small apartments, because the boiler was originally provided, including for cooking hot water and obviously more power.
Since the configuration parameter numbers for gas boilers may differ, you need to study the instructions to configure a specific model.
How to set the baxi boiler to economical mode?
For small apartments it is recommended to set parameters F08 (Maximum useful heating system output) and F10 (Minimum useful heating system output) to the minimum. The modulation range of a 24 kW boiler starts at 40% of the maximum power, so the minimum possible mode work will be 9 kW, which will be quite enough for heating an area of up to 80 square meters. meters and increase the intervals between inclusions, especially in the off-season.
In addition to saving gas, do not forget that each burner start-up activates the main actuators, relay switching on the control board, fan, gas valve, which certainly affects the resource of their work.
Here it is worth mentioning that the most economical mode of the gas boiler will be when operating at maximum power, i.e. with maximum efficiency.
Connecting a room thermostat
Most models of baxi boilers have the ability to connect a room thermostat. The meaning is that the boiler will turn on only at the signal of the thermostat when the air temperature in the room drops below the set one.
Of course, everything is quite individual, and a lot depends on the type and balance of the heating system as a whole, and the use of only one room thermostat will have a certain inertia.
Programmable thermostats allow you to flexibly adjust various temperature conditions during the day. Reducing the temperature in the room by 1 degree during the year will save about 4-5% of gas.
In some EU countries, where energy efficiency issues are more meticulous, the installation of a room thermostat is a mandatory requirement.
Zone control system
Such a system provides for individual temperature control in each room separately by installing controlled thermal heads on each radiator. That is, depending on the air temperature in a specific room the amount of coolant in the radiator will be regulated, and the boiler will turn on only when necessary. The use of such regulation will give maximum savings (about 30%) and comfort in the room. The only disadvantage of such a system is its cost.
Savings and regular equipment maintenance
The basic device of a traditional gas boiler is almost the same, regardless of the manufacturer. Thermal energy From the combustion of gas is transferred to the coolant through the heat exchanger. There can be either one or two heat exchangers in the boiler. During the operation of any gas boiler, the heat removal surface is contaminated with soot deposits from the outside, and scale from the inside.
From practice, we can say that it is extremely rare that the system is filled with specially prepared water or the water supply system is equipped with a water treatment system. Especially it concerns apartment buildings in which the owners receive ready system heating together with the apartment.
The formation of scale and soot on the walls of the heat exchanger will gradually reduce the heat transfer performance, and more energy will be consumed for heating.
Therefore, the annual regular Maintenance will necessarily affect the efficiency of equipment operation in better side! This applies in particular to boilers with bithermic heat exchangers, which, due to their structural design, are difficult to clean.

Temperature controllers are indoor and outdoor(street). Outdoor sensors can also be used.
Baxi gas equipment has the ability to connect both indoor and outdoor thermostats and sensors.
Room appliances have a greater effect on timing(switching on and off) of the boiler, and the street ones allow the unit to regulate coolant temperature. The air temperature in the street and in the house is constantly changing, and the thermostat helps increase or decrease gas flow for space heating.
Types of thermostats for Baxi gas boilers
Devices for Baxi are thermostats compatible with Italian brand gas boilers.
In terms of their functions, they do not differ from systems for other gas equipment. Usually thermostats are distinguished by:
- installation site;
- principle of work;
- control method.
According to the place of installation, the devices are divided into indoor and outdoor. Rooms are used more often than outdoor or outdoor, as they do not require protection from difficult weather conditions.
street options are used in cases where the owner of the house seeks to make the operation of the equipment as accurate and economical as possible. The combination is especially effective in such cases. room thermostat and outdoor sensor, which is allowed by Baxi units.
According to the principle of operation, the thermostat can be mechanical or electronic. In the first case temperature must be set manually. In the second- a program is laid, according to which the boiler changes the intensity of work automatically.
The way to control a mechanical thermostat is to manual installation regime turning a knob or pressing a button. An electronic or programmable version can be operated remotely. In this case, the sensor is located in any part of the room, and the control takes place remote control, computer or phone. However, contact with gas equipment remains wired.

How to choose a Baxi thermostat
Thermostats and sensors for gas boilers Baxi produced by the Italian company, so it is best to choose them. If this is not possible, you need to look for a thermostat that matches the parameters that are usually indicated in instrument data sheets. It is appropriate in such cases to take the advice of a specialist who is familiar with the Baxi brand.
Attention! Check carefully compatibility thermostat with a gas boiler for which it is purchased. Please note that devices one company interact best with each other.
When choosing a thermostat, it must be taken into account whether the boiler is used constantly or only from time to time. If the house is worth inexpensive model unit that rarely works, it is enough simple regulator with a minimum of features.
And vice versa, if heating and hot water are needed all year round and an expensive model of the unit is used, it is better to install a programmable thermostat.
And if the cottage is involved system " smart House» , then the ability to control the device via the Internet will be very handy.
This feature has been implemented in most advanced models.
Calculation technical requirements to the thermostat is made based on the requirements for the operation of the boiler. For example, if the owners leave for work in the morning and return only in the evening, thermostat with programmer, which will reduce the heating temperature and fuel consumption while no one is in the house.
And also, if the house is geographically located in a cold region, then it is better to purchase a thermostat with frost protection system: it automatically turns on the boiler if the air temperature drops up to +3°C. Such technical specifications has, for example, room thermostat Baxi Magictime Plus.

Where to post
An important condition The correct operation of thermostats is the accurate measurement of air temperature. Although all devices have an error up to several degrees, it can be minimized.
To do this, the room thermostat must be installed away from drafts and at a considerable distance from heating devices.
It is better to install the outdoor sensor so that it is not flooded with rain or covered with snow. These precautions are due to the fact that More accurate sensor readings, topics work more efficiently boiler and less fuel consumption.
What materials are needed to connect
Connection materials are usually supplied with the thermostat. This is, first of all, the device itself, as well as mounting cable and fasteners. With their help, the device is connected to a gas boiler and fixed to the wall.
What tools are required for installation
To connect the thermostat, you may need:
- screwdriver;
- drill;
- side cutters;
- thermometer.
side cutters you can strip the ends of the thermostat wires, but as a rule they already have terminals that are screwed to the contacts of the gas boiler for remote thermostat.
A drill is needed for holes in the wall into which dowels are installed. They are twisted screws on which the device is attached. Need for dowels does not apply if the wall is wooden.
A thermometer will be needed to check the air temperature after starting the thermostat.
Connection order
During the connection period, both devices should not work. To connect the thermostat and the gas boiler, it is necessary to study technical data sheets of both devices and follow the wiring diagrams and instructions. The ends of the cable for the temperature controller must be attached to the gas boiler contacts.
Then the cable must be stretched along the wall to the place where the thermostat is mounted. After that, at the selected point (usually it is located in the coldest living room), the device is screwed to the wall. Finally, it is carried out setting up and checking the device.
How to check the operation of the device
To test the device, you must set the maximum temperature. Then you need to turn on the gas boiler and bring it to mode with maximum odds useful action(efficiency).
Upon reaching a comfortable temperature, it is necessary to accurately measure it next to the thermostat and set it as a threshold for switching off.
Then, within an hour, you need to see if the thermostat turns on the heater when the air cools down. within 0.5-2 °C. If this happens, then the devices are working correctly.
