Gas water heaters reviews which is better to buy top. How to choose a geyser: guidelines for selection and rating of the best models. In what case is it advisable to install a flow-through gas water heater?
Gas water heaters solve the common problem of lack of hot water supply in a house or apartment. These portable water heaters, with minimal gas fuel consumption, are capable of providing hot water to living spaces of considerable size. The main advantages of such devices are their small size, the ability to heat a large amount of water, relative cheapness and maintainability. Among the disadvantages is the need for communications to connect speakers. At a minimum, it should be a gas pipe or cylinder, which not everyone has the ability to install, and models with electronic control or electric ignition require mains power. In addition, we are dealing with combustion products, so the installation of a chimney and ventilation is required, which complicates the installation of the device.
To choose a geyser with optimal parameters, you should pay attention to the following points.
- Depending on the power, the device can heat a certain volume of water. To service one circuit, it will be enough to buy a gas water heater with a power of up to 19 kW. If you need to heat a water intake at two points, then the model must have a rating of 20-28 kW. The most powerful water heaters (more than 29 kW) are capable of providing residents of a house or apartment with hot water in large quantities.
- If there are problems with the supply of gas or water, the solution would be to purchase storage geysers. They are equipped with tanks that store a supply of warm water. Thanks to the thermal insulation of the tank, gas consumption can be reduced.
- For the safe operation of modern speakers, manufacturers equip devices with various degrees of protection. The presence of a water flow sensor prevents the gas valve from opening when there is no flow. The thermal combustion sensor cuts off the gas supply when the wick goes out. The draft sensor stops the gas supply when the draft in the chimney decreases to a dangerous level. A water overheating sensor becomes a useful option; it not only prevents the formation of boiling water, but also reduces the amount of scale in the heat exchanger.
- Gas water heaters are controlled differently. Most often, models in the mid-price segment have two control options. One of them regulates the water pressure, and the other is responsible for the intensity of gas combustion.
- An important parameter in water heaters is the type of combustion chamber and exhaust gas removal system. In open chambers, gas burns in the upper part of the column, from where it is immediately removed into the chimney. Sealed, closed-type combustion chambers look somewhat more expensive, but safer. The supply of air, as well as the removal of exhaust gases, is forced in such devices. In addition to fans, such models use coaxial chimneys.
The most popular among buyers are heaters from Bosch, Ariston and Mora. These European manufacturers are famous for their reliability and performance. Domestic speaker Neva is excellent value for money. In the rating we will compare the best geysers in various price categories.
The best inexpensive geysers: budget up to 10,000 rubles.

Disadvantages include electric ignition that does not always work and poor heating at low pressure.
Don't study independent connecting a gas water heater without relevant experience. Moreover, this is prohibited by law (any gas inspection = fine). Connection of gas appliances should only be carried out by a specialist with a mandatory license (SRO) from his organization.
1 Ariston Fast Evo 11C
Modern burner design. Mains power supply for electronics
A country: Italy (made in China)
Average price: RUB 13,890.
Rating (2019): 5.0
Gas water heaters equipped with burners with constant power require manual temperature adjustment with each change in pressure. Ariston speakers, in contrast, are able to maintain the specified parameters independently and regardless of how many taps are open. And it's really very convenient. Ignition also occurs automatically, using electric ignition, the power source of which is a 220V household network. If the user lives in a city apartment and there are no special problems with the supply of electricity, energy dependence is quite a good option that allows you to save on batteries.
However, not all reviews are equally positive. Some blame the radiator for failure after 3 years of operation - they say it leaked or burned out. To prevent this, experts recommend that future users be very careful when installing the device and setting it to pressure according to the instructions, or resort to the services of a service center technician with access to gas equipment. In this case, the column works correctly and requires absolutely no attention.
The best geysers for several water points (pressure water heater)
For those rooms where there are several hot water intake points, pressure water heaters are the best option. Flow-through models may not be able to cope, since a sufficiently large amount of hot water needs to be supplied at the same time, and in pressure devices its level is constant (pumping is carried out), which makes it possible to provide a certain reserve, consumed by several receivers. The device is installed in a common riser, where distribution occurs.
5 American Water Heater PROLine G-61-50T40-3NV

1 Bosch WTD 27 AME
Highest power
A country: Germany (manufactured in Portugal)
Average price: 73,000 rub.
Rating (2019): 5.0
The best power indicator among flow-through gas heaters is the Bosch WTD 27 AME model. The speaker is compact in size, stylish design and high performance.

The device is equipped with an overheating sensor, which allows you to use gas economically. The water tap is equipped with an electric drive. A gas water heater is suitable for providing hot water to several water intake points; this can be done with a modulation burner.
In reviews, ordinary people and experts agree that the model is the best flow-type gas water heater. You can set it up once and not go near the device for a long time. The only drawback that stands out is the high price.
A geyser is a flow-through water heater that runs 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 simply open the tap, hot water flows out of it, and its temperature is regulated by you yourself. 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 gas water heater will also solve these problems. Heating water costs much less than it is provided centrally - this results in significant savings on utility bills. To understand which geyser 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 geyser
- gas burner device and gas removal system;
- heat exchanger;
- ignition and control module.
All these units have several modifications and their layout gives different models with different characteristics. All this allows you to choose a unit to suit your own requirements, because you can only say which geyser is better by being tied to a specific situation.
Type of ignition
For the dispenser to start working, you need to light the gas. Older models were lit manually by holding a burning match to the igniter. Today such units are no longer on sale; they are a thing of the past. They have been replaced by others that operate 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 continuously, whether there is hot water flow or not. The main burner turns on only when the tap opens. The rest of the time it is turned off.
The procedure for starting a gas water heater with piezo ignition is simple: press the button located on the front panel, a spark appears on the candles, which ignites the pilot burner. When the hot water tap opens, gas is supplied to the main burner and ignition occurs from the pilot burner. While water is being consumed, both burners are lit. The valve was closed, the gas supply to the main one stopped, only the pilot one was on again.
Piezo ignition device for geysers - a simple and inexpensive device
What are the advantages of geysers with piezoelectric elements? These are the cheapest models and usually have a mechanical control - a regulator that allows you to change the height of the flame, thereby regulating the temperature of the hot water. These models are non-volatile, which can be important for a summer residence.
There are more shortcomings and they are more serious. The wick burns (should burn) constantly while you are using the column, and this is gas consumption. Even if it is small, but constant, as a result, quite a decent amount accumulates in a month. So this is far from the most economical way to heat water. The second disadvantage 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 backdraft periodically occurs in the chimney, which blows out the flame. Since there is a flame controller, this is not a big deal - the gas shuts off automatically, but having to light the pilot burner again 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 is not lit, which significantly saves fuel. There is an electric ignition powered by batteries, and there is one from a 220 V network. Which gas water heater is better for this parameter must be chosen depending on the circumstances.
If your lights go out frequently, it makes sense to choose a battery-powered model. As you understand, in this case you have to make sure that they don’t “sit down.” If there are no problems with electricity or there is a backup power source, it is better to choose a gas water heater operating from a 220 V network. Plug the cord into the outlet once and forget about it. Electricity consumption is negligible, so they have almost no impact on bills.
Gas water heaters are electronically controlled. A board with a microprocessor is installed in the case; the desired temperature is set from a small control panel (push-button or touch). A small liquid crystal screen is often installed 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 use.
Disadvantages - higher price and power requirements. Electronics need a stable voltage of 220 V with small deviations of the order of 2 * 3 V. We cannot maintain such parameters, so in order for an 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
Heating of water in a gas water heater occurs due to the heat released during gas combustion. The combustion itself occurs in the burner, and it is “packed” into the combustion chamber. Unburnt gases that remain in the chamber are discharged through the chimney. Let's take a closer look at all these devices.
Burner - main unit
Burner
The heat source in the gas water heater is a gas burner. There are three types: single-stage, two-stage, modulated. The first two types are almost never seen lately - they do not allow maintaining a given temperature, so there is no point in considering them - all columns have a modulating burner.
Modulating burners can be controlled manually - with a special handle mounted on the body - or through a microprocessor that maintains a given water temperature. Burners are made mainly of galvanized steel, since this material is optimal for performing the assigned tasks. It is inexpensive, durable, has a high melting point, and can withstand frequent heating.
Types of combustion chamber and chimney
Combustion chambers in geysers are of two types - open and closed. Their name reflects the essence:
- closed (turbocharged, fan) is a metal box into which a burner is inserted with a socket at the top for installing a chimney;
- open (atmospheric) - this is actually the entire body of the column, since there is no isolated space, just a burner is installed in a certain place, on top there is a lid with a socket to which the chimney is connected.
Different types of combustion chambers require different chimneys. In an open chamber, air is taken from the room, therefore an effective ventilation system, normal air flow and an atmospheric chimney exiting into the ventilation duct are necessary. The closed chamber is equipped with a coaxial chimney (two pipes of different diameters inserted into one another), which is led through the wall to the street. In this case, combustion products are removed forcibly, using a fan, through the inner pipe, and oxygen flows directly to the burner through the outer pipe.
A gas water heater with a closed combustion chamber operates more stably under normal conditions, but it has disadvantages. In winter, the chimney can become overgrown with frost, causing the heater to go out (it is extinguished by an automatic system that controls the removal of combustion products). The second point is that with a strong side wind, the air flow can blow out the flame. The gas supply is turned off by the same automatic system, but the situation is unpleasant. The third circumstance is that not all city authorities allow holes in the walls of houses and the insertion of pipes.
So in this case, it is difficult to say exactly which geyser is better - it depends on many factors.
Heat exchanger
Water is heated while it flows through the heat exchanger. It is a metal pipe installed above the burner. The shape of the heat exchanger in a gas water heater is special - a pipe with fins is laid in a snake at the bottom, then a sheet of metal is installed around it, on top of which the pipe is wound in a spiral. Water flowing through this long path is heated by the heated metal.
Heat exchangers are made 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 ones are stainless steel, but they are much worse at heat transfer. Which gas water heater is better in this case is up to you to 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 the tubes are also made with thin walls. Such a heat exchanger will serve the warranty period, and then problems will 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 on the outside of the pipe, exactly in the place where condensation forms. If the pipe is of normal thickness, this is not a problem, but it quickly corrodes thin walls. Such a heat exchanger with a leak does not need to be replaced (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, and solder.
How to determine power
First of all, you need to decide on the power or performance of the gas water heater. These are two interrelated characteristics that simply reflect different characteristics of the unit. Performance 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 from your geyser. This depends on the number of consumers who need to be provided with warm water. There are consumption standards for different types of equipment:
If you have a kitchen sink, shower and washbasin connected to hot water, so that all three points work simultaneously and the water temperature does not drop, you need a capacity of 4 + 4 + 10 = 18 l/min. This is a lot, the price tag will be substantial. If you think about it, you will realize that all three devices are almost never turned 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 capacity must be 14 l/min. This is a little more modest, but quite enough for a comfortable stay. Look for the found value in the technical specifications; it should not be less.
Now let's look at power. Gas water heaters can allocate from 6 kW to 40 kW of heat for heating water. Here the division is:
- a gas water heater with a capacity of up to 19 kW is suitable for heating water for one water collection point;
- for 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 geysers that are worth paying attention to. First, look at the minimum water and gas pressure that this model can work with. Imported gas water heaters from European manufacturers are more capricious in this regard - they are designed for stable pressure and do not tolerate changes well. 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 surges. If the model you like does not have such a device, and your water and/or gas pressure fluctuates, you can install the reducer in front of the entrance to the dispenser. This device is simply placed into a pipe break; installation is standard. At the same time, your other consumers will be protected.
It is also useful to review the list of utility programs and protection levels. The safety and comfort of equipment operation 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, it shuts off the gas supply.
- Traction control. The presence of draft in the chimney is controlled. If 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 there is none at all.
- Overheat protection. The temperature sensor monitors the temperature of the water in the heat exchanger; when it approaches a critical point (boiling), it turns off the column. This extends the service life of the equipment (if it boils, the heat exchanger can rupture, as can the pipes).
These functions are necessary for the safe operation of the geyser. This is almost a standard set that is found in all good gas water heaters. All others are optional. They, as a rule, are no longer so critical (for example, the remote control).
Geyser sizes and prices
The overall dimensions of gas water heaters are small - they are comparable to a small wall kitchen cabinet. The average height is 550-650 mm, width 300-400 mm, depth 200-300 mm. But if you wish, you can find models that are wide and flat, or vice versa, narrow and deep. Which geyser is better based on this parameter can only be determined by reference 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.

- To select a suitable speaker, both for a city apartment and for a country or country house, you first need to decide on the power of the device. The performance of the column will depend on it - both the speed of heating the water and the ability to supply water to several points. Low-power devices (up to 20 kW) are capable of heating about 10-11 liters of water per minute and providing only one water collection point. The higher the power of the device, the more points it can simultaneously provide with warm water and the larger volume of water will be heated by such a column in one minute.
- The next parameter that distinguishes geysers is the type of ignition. Consider whether you need a device with piezo ignition, since such equipment is cheaper, but the gas consumption in such a column will be higher than in models with more modern electric ignition. When piezo ignition, you need to press a button, and inside the device the igniter is always lit, consuming gas in vain. It is more convenient to use an electric ignition, but difficulties can arise with it. If it is powered by batteries, then they need to be replaced approximately once a year, and devices in which ignition is activated by a hydraulic turbine require a fairly high water pressure.
- The cost of the column is also affected by the type of burner. In more expensive devices it is modulating, that is, it is capable of maintaining a certain water temperature regardless of the pressure in the pipes.
- When choosing a speaker, it is very important to pay enough attention to the safety of its use. The homeowner must be sure that the device will not harm the health of users and the premises in situations such as lack of draft, reverse draft or flame extinction. So find out what sensors that ensure safe operation of the column are in the selected device.
You will learn many useful nuances about choosing a gas water heater by watching the following video.
It is illogical to rely on a centralized supply of hot water for a huge number of reasons - the cost of services here is high, and its quality leaves much to be desired. In this case, you can choose a good geyser and get warm water at any time of the day. It is for this purpose that this rating was compiled, based on customer reviews. The TOP describes the advantages and disadvantages of the most reliable water heaters for home and apartment, after studying which you can make your choice easier.
Usually, the products of Chinese, Japanese and Korean companies are widely represented in the ratings. In the case of gas equipment, the leaders are European, including Russian, companies. Each of them has occupied its own niche and has an excellent reputation. These are the winners:
- Ariston is a European company that produces equipment for heating premises and supplying them with hot water. It has a range of boilers and water heaters, including gas type. They are distinguished by their versatility and functionality, since in most cases they allow both automatic and manual temperature adjustment with an accuracy of 1 degree.
- Baxi is another popular European company headquartered in the UK. Its products are powerful enough to serve effectively even in a large family. On average, their productivity is 10 liters per minute and their power is 19 kW. Most of the equipment is designed for wall mounting. It comes with a 1-2 year warranty.
- Bosch– this company needs no introduction, being a leader in the market of household appliances, heating and water equipment. It attracts attention with the optimal ratio of quality and price of goods, reliable warranty service and a developed distribution network. Basically, we are talking about storage water heaters with a capacity of about 17 kW. Their cost depends primarily on this parameter, and the higher it is, the more expensive the price. It produces the best, according to customer reviews, geysers.
- Electrolux is a Swedish concern that occupies a leading position in the ratings of gas equipment manufacturing companies. The choice of speakers here is not very large, but the available models are worthy of attention - they are equipped with storage tanks with good thermal insulation, carefully processed to prevent corrosion, and operate in an economical mode. They are guaranteed for a period of 2-5 years, which only confirms the high quality of assembly and components. At the same time, the company’s devices are affordable and their purchase does not put a large burden on the budget.
- Neva Lux– compared to other manufacturers in the rating, this is a relatively new company, formed as a result of the renewal of the Neva company. Gas water heaters from the premium category are sold under this brand. They are manufactured in Russia, at the Armavir Gas Equipment Plant. The products are supplied throughout the country and are easy to find in stores.
You can find detailed descriptions of products, as well as familiarize yourself with company policies on their official websites.
Rating of the best geysers
The compilation of this TOP was made possible as a result of a careful selection of applicants, as a result of a comparison of their characteristics and a careful analysis of customer reviews.
Here are the parameters we paid attention to:
- Quality of materials and workmanship;
- Weight and dimensions;
- Easy to install;
- Requirement for maintenance;
- Quiet operation;
- Water heating speed;
- Operational safety;
- Functionality – presence of a display, thermometer, etc.;
- Ignition method – manual, electric or piezo ignition;
- The pressure range at which the equipment operates;
- Support for multiple water points;
- Installation method: floor or wall.
The key parameters when selecting the best geysers were expert reviews, operating power and the amount of water that the equipment can heat per minute.
Which is better - storage or instantaneous water heater?
A storage water heater is a boiler that has a built-in heating element and a thermos tank that holds warm water. In the flow-through version, there is no such container; it becomes warm during the operation of the column.
Here is a table comparing the two types of models:
| Type | pros | Minuses |
| Flow-through | Low prices | Not the best option for large houses and apartments |
| Light weight | When used simultaneously in different rooms, the water temperature may drop. | |
| Easy installation | Doesn't work well with three or more water distribution points | |
| Easy maintenance | ||
| A wide range of | ||
| Cumulative | Unpretentiousness to gas pressure | When the water runs out, the force of the stream becomes less |
| Low voltage requirements | High price | |
| Efficient operation even with minimal tap pressure | Maintenance requirements | |
| No need to wait for water to heat up | Heavy weight |
Thus, in small families it is quite possible to use an instantaneous water heater, and in a spacious house it is no longer possible to do without storage equipment.
The best storage water heaters
Such devices are most often designed for floor installation. In fact, these are ordinary boilers, only running on gas. They pre-heat the water, which accumulates in a special tank. Its average volume is 150 liters. Among the best geysers, this rating presents the most interesting models.
This is a good floor-standing speaker for those who spend little time at home or live alone in an apartment. Its power is not very large, 8.65 kW, so the water does not warm up quickly, but efficiently. The presence of a built-in thermometer allows you to control this process, although the device quite successfully copes with this on its own. Stainless steel housing ensures long service life. The Ariston SGA 200 model is adapted to work in low pressure conditions and consumes gas economically, which is a key point in its choice.
Advantages:
- Capacious water tank of 200 l;
- Heats water well;
- Wide operating temperature range, up to +75 degrees;
- Does not require matches for ignition;
- Does not require an electrical connection;

- Not the most voluminous tank - 100 liters.
The best instantaneous water heaters
As the name of the category suggests, these models of geysers heat water directly at the moment it is supplied to the tap. Due to this, they are cheaper than storage heaters and their choice on the market is much wider. In the category of the best geysers, we present 4 flow-type models.
The speaker is included in the rating due to its convenience and practicality. It lights up at the touch of a button thanks to the piezo system. In this case, the flame strength can be adjusted, if necessary, depending on the water flow. This allows you to simultaneously use it in both the bathroom and the kitchen without losing temperature. Even when operating at maximum power of 26.2 kW, gas consumption does not exceed 2.1 m3/hour, and liquefied gas consumption is almost half as much. This model has a guaranteed service life of 10-15 years and is unpretentious in maintenance. But just in case, the buyer is still given a one-year warranty, which can be extended to two years.
Advantages:
- Heats water up to 60 degrees;
- Operates at a power of 17.40 kW;
- Effective at a minimum pressure of 0.10 atm;
- Prepares up to 10 liters of water per minute;

The best inexpensive geysers
Gas equipment is considered cheap, the cost of which does not exceed 4000-6000 rubles. There are not many such models on the market, but we still found one inexpensive option with good quality indicators.
It is difficult to find a cheaper model than this model in the rating of geysers; the manufacturer made it simple, but safe and of high quality. It adequately performs its main function of heating water. But at the same time, it must be controlled manually, although the device is ignited by electric ignition. A unique option here is the ability to switch to “winter” or “summer” operating mode, depending on the season. This allows you to save on gas consumption and pay less for it, which is always relevant.
Advantages:
- Heating temperature limitation;
- Operates under pressure from 0.25 to 10 atm.;
- Protected from freezing;
- Simple fastening method;
- Doesn't overheat;
- Power 17.4 kW;
- Warming up water at a speed of 10 l/min.
Flaws:
- Mechanical control.
Which gas water heater is better to buy?
If you need the equipment to serve both the kitchen and the bathroom at the same time, then its productivity should be higher than 10 liters per minute. For work in Khrushchev-era buildings, especially on the top floors, it is important that the device can operate under conditions of low gas pressure (below 0.15 bar) and low water pressure. Those who do not want to control its operation should pay attention to models with electric ignition and a flame modulation option. Products with a heat exchanger made of copper or steel can reduce heat loss as much as possible.
Here's what you can choose, depending on your needs:
- For one or two people, the Ariston SGA 200 or Baxi SAG3 100 will be quite sufficient;
- In private homes, the powerful Bosch Wr 10-2p model would be very appropriate.
- In an apartment, especially in old houses, Ariston Fast Evo 11C will be relevant.
- To service several water points, it is best to choose the Electrolux GWH 11 PRO Inverter.
- If you need a budget option, then you should pay attention to the Neva Lux 5514 or Superlux Dgi 10l gas water heater.
The rating included only the best geysers existing on the market, but they, as you can see, have certain nuances. Therefore, before purchasing, you must carefully read the description and characteristics of the product.
