The model is ideal for apartments where there is a very weak water pressure and may well last 5-7 years. Vector JSD-20W can be purchased for an amount within 8 thousand rubles.

price 7 thousand rubles

Geysers "" from domestic manufacturer is a good budget option and is not much inferior to foreign counterparts. The device has a thermostat that regulates the temperature of the water and does not allow it to heat up by more than 60 degrees. The device is equipped with automation: it starts working only in the presence of a pilot flame and water flow. If there is no draft in the chimney and the igniter goes out, then the main burner is turned off. These are quite reliable and good quality models. But there are some disadvantages: 1) the device is a bit noisy during operation; 2) gas does not get automatic access to the burner when the water tap is opened, so ignition is carried out manually; 3) with a weak pressure of water, it will be difficult to make the column work. But such small flaws can be forgiven for a very affordable price - 7 thousand rubles.

price 9 thousand rubles

Slovenian geysers are among the highest quality and most reliable. Let's take a closer look at the line of water heaters on the Gorenje GWN 10NNBW model.

price 11-19 thousand rubles

Speakers of the series lead the rating of the most reliable and high-quality gas equipment this year. The water heater is equipped with a modulating burner, which itself controls the power and ensures a stable temperature. Thus, the consumer is not in for an unpleasant surprise when warm water may be replaced by a cold stream. Safety plays a major role when choosing a device. The company has thought this point through and provided its devices with a reliable automatic protection. In case of incorrect operation, the column is turned off. One of the latest Fast Evo models is equipped with an ignition from electrical network, which does not require unnecessary manipulations from the user. The pricing policy of this line ranges from 11-19 thousand rubles.

Water heaters are necessary not only for residents of the private sector, but also for people living in apartments. The central water supply is not always stable, the water supply is turned off to repair and prevent the system. In the summer, without hot water supply (hot water supply), it is difficult. Which geysers are better to choose in order to feel comfortable at any time of the year? What equipment to buy for installation in Khrushchev, a private house or modern apartment? To help you with the choice, we have compiled a rating of the best models according to users and experts.

Which gas column to choose? With some criteria you need to decide before going to the store. Look around your premises. Is it spacious or cramped? Is the wiring installed old or new? How long have the pipes been changed? Why the answers to these questions are important, you will now find out.

Device power. More powerful devices consume a large number of electricity, therefore, require connection to thick wiring. It is worth focusing on the number of sampling points. So, a low power of 9-20 kW can provide one point of intake. Average 20–24 kW - two points. High 25 kW and above - two points with stable operation or three with pressure drops.

Combustion chamber type. Products open type represent classic design. The air that is needed to burn the flame is taken from the room. Therefore, it is important natural ventilation. The products of combustion are removed through the chimney.

closed kame ra provides for the installation of a coaxial chimney. It is based on the principle of a pipe in a pipe. Combustion products are removed through one tube, oxygen for combustion enters through the other. The safety of such devices is much higher. Therefore, they are preferable for installation in a residential area.

Ignition type. This is an important criterion on which the convenience of using equipment depends.

With auto ignition. The burner ignites when the mixer is opened. There are water and gas regulators on the panel, it is possible to have a display.
With piezo ignition (semi-automatic). To start the burner, you need to hold the button. The cost of such models is lower, but in operation they consume a large amount of fuel.
Manual ignition was used in outdated models. It is inconvenient and unsafe.

Safety. When buying, pay attention to this criterion. The presence of flame sensors, thrust, temperature allows you to protect the device from damage, and the user - from poisoning. If the column fails, the sensors signal the control module, after which the operation is turned off.

Choice problems

Which devices are better - domestic or imported? Someone thinks that Russian and Belarusian speakers are the most reliable. The cost of products is much lower than imported ones, besides, they are easier to repair and find spare parts.

Foreign products are often assembled in our country from Chinese parts. Of course, this is much more profitable for manufacturers. It turns out that the client overpays only for the brand / brand, but the equipment is the same?

Another example in favor of a domestic manufacturer. Products are adapted for normal operation in our "not normal" conditions. That is, the column can operate at a minimum system pressure of up to 0.1 bar. And this is true for residents of Khrushchev, where the old water supply is installed. by the most well-known manufacturers are "", "", "Don". Staurolit and Vestal are also in demand.

On the other hand, if you turn to an official supplier, you can purchase high-quality imported equipment. Yes, it will cost more. Yes, in the event of a breakdown, you will have to order original spare parts. But reliable parts, high-quality components and materials will do their job. Such a product can last more than 10 years. Much depends on the operating conditions.

Sergey

Powerful and high quality speaker. Suitable for hard water, I have been in operation for the fifth year. This is despite the fact that in the water there are impurities of sand that precipitate. So I added a filter. The assembly is good, it provides stable 2 intake points - in the kitchen and in the bathroom. Periodically I clean the heat exchanger, because not a single device can withstand such water for a long time. In general, I am satisfied with the work. One minus - the regulator cannot turn off the operation of the batteries. Pulling them out every time is inconvenient.

"Ladogaz" VPG 10E

The product is perfectly adapted to the Russian realities of operation. There is no igniter in the design, which makes it safe to use. The device will work even at a system pressure of 0.1 bar. Power 19 kW. Productivity 10 liters per minute. The maximum heating temperature is +85 °C.

Peculiarities:

The protection system includes: safety valve, temperature sensor, gas control, ionization sensor.
The panel has two adjustment knobs and a display for temperature control.
Electronic ignition.

The cost is from 7,000 rubles.

We chose HSV 10E of "our" production to ensure hot water apartments. During the work, she noted economical gas consumption, in contrast to the device with piezo ignition, which was before. Heats liquid quickly, good pressure. The body dimensions are very compact. We don't have a lot of space in our kitchen, so the design fits comfortably. If you value a domestic manufacturer, then choose Ladogaz.

Roda JSD20-T1

The Swedish trademark "Roda", but the assembly is Chinese. Despite this, users respond positively to this model. Power 20 kW, 10 l/min. enough to provide two points. Modern technology is equipped with electric ignition. The flame lights up only when the mixer is opened, which saves electricity.

The work is designed for pressure from 0.30 to 8 atm. The structure is equipped with heaters. When the temperature in the radiator drops to +5 degrees, heating is turned on, preventing the product from freezing. Closed combustion chamber.

The Roda JSD20-T1 can be placed comfortably thanks to its slim design.

Gennady

Absolutely satisfied with the purchased equipment "Roda". First, it works stably. The temperature is kept in the set mode, does not jump. Secondly, the compact body and neutral design. For those who are going to buy, I will inform you: this model is intended for installation in a private house. It connects to a coaxial chimney, which is not suitable for apartments. A friend tried to install it in an apartment, I had to buy a new device.

Hyundai H-GW2-ARW-UI307

The water heater from the Chinese manufacturer is equipped with a copper heat exchanger. Operating power 20 kW, output 10 l/min. You no longer need matches, automatic ignition allows you to comfortably use the product. The burner is made of stainless steel.

Vladislav

Reliable durable housing H-GW2-ARW-UI307, does not heat up when turned on. The water is at a stable temperature, you do not need to constantly keep your hand on the tap to wash. I hardly use power control, as I installed it on minimum position, that's how it works. I do not understand how it differs from the temperature. For the price it's a great unit.

Superflame SF0120 10L

"Superflame" refers to the category of models with an average performance (17.85 kW, 10 l / min). The affordable cost of flow heaters makes them in demand among different segments of the population.

Dmitry

Many complain about the heating rate, poor assembly. I will say this: do not fumble in the setting - do not take it. If a person does not understand the instructions, it is clear that fiddling with the device is a burden. The unit is designed for a separate chimney, preferably in own house. The temperature was set once in the region of 38–40 degrees. The heat is excellent, no need to mix. A family of 4 has enough hot water, all the households are overjoyed.

On the panel there is a lever for smooth regulation of temperature up to +60 degrees. The column produces 10 liters of water per minute, the average power is 17.4 kW. It will function even at a pressure of 0.10 atm.

Semi-automatic piezo ignition helps the equipment work stably, the igniter is always on fire. The device automatically turns off when overheating, an ionization sensor is installed. It can be connected to a common line or run from a gas cylinder. The device works quietly, which will not prevent the owners from spending time in the kitchen.

The cost is from 8 000 rubles.

Julia

I chose a water heater for a long time and settled onBosch WR 10-2P with piezo ignition. Met negative feedback that the radiator is leaking. I have been using the equipment for three years, no problems. It is necessary to clean the heat exchanger in time and do not install high temperature. I adjusted it once, and after that it consistently produces hot water. I recommend to buy.

Even the best, according to buyers, technology has its drawbacks and advantages. No wonder they say that best repair is prevention. If you have made your choice trademark devices, we give several recommendations for long-term operation:

To install the product, it is better to contact a specialist.
It is not recommended to mix hot and cold streams on a mixer.
Once a year, inspect the column nodes.

We wish you a good choice!

Here is the check :)
We changed the column about 3 years ago, chose for a long time and came to the conclusion that you need to buy in specialized offices, and not in stores with household appliances. Bought - "Water heater gas BOSCH WR 13G", manufactured by JUNKERS Bosch Gruppe Germany. It cost then 10,200 rubles, but there were also cheaper ones depending on the functions. This one is ignited under the pressure of water, and some of them have a wick that burns all the time, like on our old speakers.
The master who installed said that it was from household the best choice:) Maybe, of course, he says so to everyone, but so far we are satisfied.

Quote: I think that many forum regulars have centralized hot water supply and for them the topic of a gas water heater is very far away ... Many in old houses during repairs replaced "columns" with storage-type boilers.

We have been using the Valiant column for 10 years, at that time it was the best choice. Last year, they changed some part (it burns out over time), there was a question about replacing the column itself, but the master advised all the same to replace the part, because. will last another 5-6 years. Although at the moment there are some good analogues, unfortunately, I don’t remember the names of the companies that are engaged in the production of water heaters. In any case, Valiant is a great technique, compared to Bosch, Electrolux and others that our neighbors have, we do not know any trouble.

I’ll also write about my Vaillant (I looked at how it’s spelled correctly) - this part, which we changed 9 years after the purchase, is a heat exchanger, one of the weak points of all columns, and so Vaillant still serves for a long time compared to others, because it is made of some kind of super-copper alloy. Replacing a heat exchanger is quite expensive, last year it cost about 10-11 thousand. Yes, and our neighbors, who have Electrolux and Bosch, periodically clean them, that is, they call specialists for this. We also decided to call (well, why are we worse!), The master came, looked - there was nothing to clean. I don’t know what it depends on more, on the column or something else (maybe the neighbors are constantly washing).

I bought AEG GWH 11 ERN 4 years ago at first it worked without failures, everything was very pleasing! At one point, the water pressure disappeared at the outlet and, as a result, the flame of the main burner stopped igniting! Bottom line: either buying a new gearbox (I’ll immediately notice self repair did not lead to anything only to money spending) the official service costs 2/3 of the cost, or a new gas column (rather the second, but not from this manufacturer). By the way, as it turned out, the same breakdown did not occur to me alone, only the Electrolux brand (which owns AEG)!
Conclusion: if you are ready to pay every four years for a new gas water heater, then the choice is good due to the low price.

Geysers are versatile, economical and easy-to-use flow-type water heaters. The basic principle of their operation is the combustion of gas inside the boiler, due to which the gas passing through the column is heated to the desired temperature. cold water. The fuel used is both natural gas and liquefied gas in balloons. With compact dimensions, geysers cope with any volume of water. This type of heating is more economical than electric. Our rating of the best gas water heaters 2019 will help you to learn more about gas water heaters, choose the most modern and reliable model.

In order to choose a geyser that is ideal for you and your living conditions, you should familiarize yourself with the complete set and the simplest classification of this water heating device, which is indispensable for many users.

Equipment geyser includes:

If it is impossible to put a gas water heater (and this may cause difficulties if the apartment was not designed for the water heater, then the only way out for using hot water is.

a connector with a chimney through which harmful combustion products and an exhaust hood exit;

heat exchanger;
gas and water units;
diaphragm type gas valve;
back panel and batteries;
control panel: power (outlet temperature) and water flow regulators;
ignition block.

Ignition type is one of the column selection criteria. Distinguish:

manual ignition type- the column is kindled with an ordinary match.
piezo ignition - a type of ignition that replaced manual ignition - the mechanical appearance of a spark from which the system ignites. To supply hot water, the pilot burner must be constantly on.
electric ignition - ignition is carried out by means of an electric spark. There is no permanently burning pilot wick, which saves gas consumption.

Unlike columns with manual type switching on, to work with a column equipped with an electric or piezo ignition system, you just need to open the water, and it will do the rest for you. High level automatism captivates many users, because using a gas water heater is no more difficult than using an ordinary electric boiler.

Power- this criterion is considered based on the number of family members and the budget you are counting on. By power they distinguish:

low-power speakers: 17-19 kWh - the best option for a family of up to 3 people;
medium power speakers: 22-24 kWh - this type will be useful for a family of 3-5 people;
high-power speakers: 28-31-kWh - the most suitable option for a large house.

Temperature regulation:

modulation - modulating burners at any pressure of water give the set temperature.
constant power - the temperature is regulated in accordance with the pressure of the water.

chimney- There are two main varieties:

turbocharged - equipped with a fan that forcibly draws combustion products through the chimney into the street. Models with a turbocharged type of chimney are safer, but noisy and expensive.
with natural smoke removal - the process of removing combustion products occurs exclusively due to natural draft. Thanks to this, the work is carried out completely silently.

Of course there is a number of additional criteria on which the choice is made. For example, this:

safety - a column is considered safe if it has more than three levels of protection (the main ones are: auto-blocking when the flame goes out, stopping the gas supply in the absence of traction and overheating protection). Modern geysers are protected from harmful gas leaks and, moreover, from explosions and fires.
design - a rather unpleasant stereotype has developed that a gas water heater is ugly. Most manufacturers produce stylish, modern models that are very different from gas water heaters produced in the USSR. small flow column can be built into a special wall cabinet with doors. There are also models with drawings or ornaments: there are many options and you are sure to find the most suitable for you.
control type: mechanical or electronic. Columns with electronic type are controlled using buttons or in the most modern models– touch screen, with mechanical type– by means of rotary switches. The first type is more "advanced" and is equipped with internal program memory.

Summing up

Geysers can help make life even easier, the main thing is to choose the best option for your living conditions. Economical and simple geysers are suitable for members of small families, a more demanding user will like multifunctional ultra-modern models with displays and many additional parameters. If you are concerned about the issue of safety, pay attention to models with gas leakage protection systems during operation.

Geyser - instantaneous water heater running on natural gas. If you do not have hot water supply, but gas is supplied, this equipment will increase the comfort of your life. You just open the tap, hot water runs out of it, and its temperature is regulated by you independently. Even if you have a centralized supply of hot water in your house or apartment, but you are not satisfied with the price you have to pay for heating, or perhaps you are not satisfied with the temperature, installing a geyser will also solve these problems. Heating water costs much less than it is provided centrally - that's a significant savings on utility bills. To understand which gas column is better, you will have to study the structure of the equipment and its types. Then the choice for you will be simple and conscious.

The structure of the gas column

gas burner and gas exhaust system;
heat exchanger;
ignition and control module.

All these nodes have several modifications and their layout gives different models With different characteristics. All this allows you to choose a unit for your own requirements, because you can only say which gas water heater is better by being tied to a specific situation.

Ignition type

In order for the column to start its work, it is necessary to ignite the gas. Old models were lit by hand, bringing a burning match to the igniter. Today, such units are no longer on sale, they are a thing of the past. They were replaced by others that work in automatic or semi-automatic mode.

Piezo ignition

In geysers with a piezoelectric element, ignition occurs in a semi-automatic mode. There are two burners - main and pilot. The pilot burner is a small wick that burns constantly, whether there is hot water flow or not. The main burner turns on only when the valve is opened. The rest of the time it is off.

The procedure for starting a gas column with piezo ignition is simple: press the button displayed on the front panel, a spark appears on the candles, which ignites the pilot burner. When a hot water tap is opened, gas is supplied to the main burner, ignition takes place from the pilot burner. While water is flowing, both burners are lit. The valve was closed, the gas supply to the main one stopped, only the pilot one is on fire again.

Piezo ignition device for gas water heaters - a simple and inexpensive device

What are the advantages of geysers with piezoelectric elements? These are the cheapest models, they usually have a mechanical control - a regulator that allows you to change the height of the flame, thereby regulating the temperature of hot water. These models are non-volatile, which can be important for giving.

There are more disadvantages and they are more serious. The wick burns (should burn) constantly while you use the column, and this is gas consumption. Let it be small, but constant, as a result, quite a decent amount accumulates in a month. So it's far from the best. economical way heat the water. The second minus is also associated with the burning of the wick. If it goes out, you will not be able to light the column. The wick goes out because it does not have enough oxygen to burn, or because a reverse draft periodically occurs in the chimney, which blows out the flame. Since there is a flame controller, this is not a problem - the gas is automatically shut off, but the need to re-ignite the pilot burner is unpleasant.

Electric ignition

Automatic geysers have electric ignition. This is an electric spark generator that is activated when the tap is opened. The rest of the time the gas does not burn, which significantly saves fuel. There is an electric ignition, powered by batteries, there is - from a 220 V network. Which gas water heater is better for this parameter, you have to choose according to the circumstances.

If you often turn off the light, it makes sense to choose a model that runs on batteries. As you understand, in this case, you have to make sure that they "do not sit down." If there are no problems with electricity or there are backup source power supply, it is better to choose a geyser powered by a 220 V network. Once they plugged the cord into an outlet and forgot about it. Electricity consumption is negligible, so they have almost no effect on the bills.

Geysers automatic machines have electronic control. A board with a microprocessor is installed in the case, the desired temperature is set using small panel control (button or touch). A small LCD screen is often placed here, which displays the current state of the equipment, the temperature of the water, if it is being heated. This type of geyser is the best if you value ease of handling.

Disadvantages - higher price and power requirements. Electronics needs a stable voltage of 220 V with slight deviations of the order of 2 * 3 V. We do not maintain such parameters, so in order for the automatic gas water heater to work for a long time, a stabilizer is required, and it is better not a relay, but an electronic one. It not only stabilizes the voltage, but also evens out the shape of the pulses, which is also very important for imported water heaters.

Burner, combustion chamber, chimney

The heating of water in a gas column occurs due to the heat released during the combustion of gas. The combustion itself takes place in the burner, and it is “packed” into the combustion chamber. Unburned gases that remain in the chamber are discharged through the chimney. Let's consider all these devices in more detail.

Burner - main assembly

Burner

The heat source in the gas column is gas-burner. There are three types: single-stage, two-stage, modulated. The first two types in recent times almost never occur - they do not allow maintaining the set temperature, therefore it makes no sense to consider them - all columns have a modulated burner.

Modulating burners can be controlled manually - with a special handle mounted on the body - or through a microprocessor that maintains the desired water temperature. Burners are made mainly of galvanized steel, as this material is optimal for the task. It is inexpensive, durable, has a high melting point, and normally tolerates frequent heating.

Types of combustion chamber and chimney

Combustion chambers in gas columns are of two types - open and closed. Their name reflects the essence:

closed (turbocharged, fan) is a metal box into which a burner with a socket at the top is inserted to install a chimney;
open (atmospheric) - this is actually the entire body of the column, since there is no isolated space, just a burner is installed at a certain place, there is a cover with a socket on top, to which the chimney is connected.

Different types of combustion chamber require a different chimney. AT open chamber air is taken from the premises, therefore, an effective ventilation system, a normal air supply and an atmospheric chimney leading to the ventilation duct are necessary. The closed chamber is equipped coaxial chimney(two pipes different diameter inserted one into the other), which is displayed through the wall to the street. In this case, the products of combustion are removed forcibly, with the help of a fan along inner tube, and oxygen enters immediately to the burner through the outer.

A geyser with a closed combustion chamber works more stably under normal conditions, but it has drawbacks. The chimney can become frosty in winter, which is why the column goes out (it is extinguished by automation that controls the removal of combustion products). The second point is that with a strong side wind, a flame can be blown out by a stream of air. The gas supply is turned off by the same automation, but the situation is unpleasant. The third circumstance is that not all city authorities allow holes in walls in houses and pipes to be introduced.

So in this case, it is difficult to say exactly which gas column is better - it depends on many factors.

heat exchanger

Water is heated while it flows through the heat exchanger. He is metal pipe installed above the burner. The shape of the heat exchanger in the geyser is special - a pipe with fins is serpentine in the lower part, then a sheet of metal is installed around it, over which the pipe is wound in a spiral. Flowing along this long path, the water is heated by the heated metal.

They make heat exchangers from galvanized steel (the most budget option), stainless steel and copper. The best in terms of efficient heat transfer are copper. They are the most economical, but also expensive. The most durable are stainless, but they have a much worse situation with heat transfer. What's in this case the gas column is better - you decide. Choose the quality that is more important to you.

If you decide to buy a gas water heater with a copper heat exchanger, do not try to find a cheap model. In order to reduce the price, manufacturers use low-quality copper, and even tubes are made with thin walls. Such a heat exchanger will serve guarantee period, and then problems begin - a leak will appear.

If you remove the casing, you will see fistulas in the tubes through which water drips. They are located mostly in outside pipes, just in the place where condensation forms. With a normal pipe thickness, this is not scary, but thin walls quickly corrode. Such a leaky heat exchanger does not have to be changed (it costs about 1/3 of the total price), it can be soldered. You will need refractory solder with a melting point of about 200 ° C, a powerful soldering iron and soldering flux. The technology of work is usual - clean the damaged area to bare metal, degrease, tin, solder.

How to determine power

First of all, you need to decide on the power or performance of the gas column. These are two interrelated characteristics, simply reflecting different characteristics unit. Productivity is how many liters of water a column can heat per minute, and power is how much heat it can release. Some manufacturers indicate power, others indicate performance, so you need to understand exactly what you need.

Let's first figure out what kind of performance you need a geyser. It depends on the number of consumers that need to be provided. warm water. There are consumption rates for equipment of different types:

If you are connected to hot water kitchen sink, shower and washbasin, so that all three points work simultaneously and the water temperature does not fall, a performance of 4 + 4 + 10 = 18 l / min is required. This is a lot, the price tag will be solid. If you think about it, you will understand that all three devices almost never turn on at the same time. There are situations when the shower and one of the taps work together. To provide them with hot water, the productivity should be 14 l / min. This is a little more modest, but quite enough for comfortable living. Find the value found in technical specifications, it should not be less.

Now let's deal with power. Geysers can allocate from 6 kW to 40 kW of heat for heating water. Here the division is:

a geyser with a power of up to 19 kW is suitable for heating water for one point of water intake;
at two points, the power should be from 20 kW to 28 kW;
three require more than 29 kW.

Now, you can definitely say which geyser is better in terms of power in relation to your needs.

What else to look for when choosing

There are a few more lines in the technical characteristics of gas water heaters that you should pay attention to. First, see the minimum water and gas pressure that this model can handle. Imported geysers of European manufacturers are more capricious in this regard - they are designed for stable pressure, they do not tolerate drops. But under normal conditions, they work stably and without breakdowns.

Some manufacturers, in order to adapt their equipment to our conditions, install gearboxes that compensate for jumps. If there is no such device in the model you like, and your water and / or gas pressure jumps, you can install the reducer on in front of the column entrance. This device is simply placed in a pipe break, installation is standard. At the same time, other consumers will be protected.

It is also useful to study the list of service programs and protection levels. The safety and comfort of the equipment depends on them. It is highly desirable to have the following functionality:

Gas control. Monitors the presence of a flame on the burner, if it goes out, shuts off the gas supply.
Traction control. The presence of draft in the chimney is controlled. If the combustion products are not removed, the gas supply is shut off.
Flow control or hydraulic valve. Turns off the column if the water pressure is too weak or not at all.
Overheat protection. The temperature sensor controls the temperature of the water in the heat exchanger; when it approaches a critical point (boiling), it turns off the column. This prolongs the life of the equipment (when boiling, the heat exchanger can break, like pipes).

These functions are necessary for the safe operation of the geyser. It's practically standard set, which is in all good gas water heaters. All others are optional. They, as a rule, are no longer so critical (for example, the remote control).

Sizes of gas water heaters and prices

dimensions gas water heaters small - they are commensurate with a small hanging kitchen cabinet. Average height - 550-650 mm, width 300-400 mm, depth 200-300 mm. But if you wish, you can find models wide and flat, or vice versa, narrow and deep. Which gas water heater is better for this parameter can only be said by being tied to the installation site, so there is no definite answer here either.

Prices for geysers vary widely. Simple Models with piezo ignition and a galvanized burner cost from $110. Equipment with electric ignition and a bunch of service functions - up to $ 450. So there is somewhere to roam.
