How to choose a good model for an apartment?
The most important criterion when choosing a model of a flowing geyser is its performance - the flow rate of liters of water per minute. The higher this indicator, the more efficient the water supply in the column will be. However, it is worth noting that a good geyser does not necessarily have to have maximum performance in the technical data sheet. Everything is directly proportional to several factors: the number of people living in the apartment, how many of them need to use hot water at the same time, as well as the number of mixers.
Another important criterion is thermal power. This indicator will help you figure out how many sources a gas water heater can provide with hot water at the same time. The minimum indicator is a mark of 17 kW - this type of water heater is able to ensure the operation of one mixer.
It is worth noting the criterion for the type of ignition of the gas column. The best option would be a water heater with electric or piezo ignition. They are automated and do not cause operational inconvenience to owners. To date, they are the most economical and modern, in contrast to the already out of circulation columns with a manual type of ignition.
The key factors when choosing a device can also be: weight, design, dimensions of the equipment, type of communications, equipment, a set of automated protective functions and, of course, the average price of the column. Together, all these indicators should correspond to a certain type of use - it is best to consult with the seller of the intended place of purchase to determine the optimal model of the water heater.
How to install and connect correctly?
Improper installation or installation of the gas unit can be a serious threat to the life and health of the user. To avoid such consequences, it is worth following a certain procedure. After purchasing gas equipment, in order to register it and confirm the possibility of installing it indoors, you must:
- Write an application to the gas distribution company.
- Get a plan from BTI or Rosreestr.
- Provide an extract from Rosreestr confirming ownership.
- Contact the relevant organization to draw up a project.
- Find certified specialists from an organization that has a permit for gas work.
It is very risky to engage in communications and installation of the column yourself. The best way out is to call the wizard, who will qualitatively connect the device, help to understand the intricacies of its use.
In addition, incorrect or unauthorized installation of a gas water heater is punishable by significant fines, not to mention the fact that due to the threat created, people's lives can be in danger.
Entrust the work to professionals, asking in detail about all the nuances of his work, in order to further protect yourself and people close to you.
Geysers are widely used in private housing construction for heating water. They are economical and easy to operate. Manufacturers produce a wide range of equipment that differs in technical characteristics and design features. When choosing it, it can be difficult to figure out which gas water heater is better to buy.
Geysers are instantaneous water heaters. They belong to household appliances and compete with electric boilers. Among the advantages of gas units:
- the possibility of instant heating of water;
- ease of operation;
- aesthetic appearance and compactness.
Note! The low gas consumption rate makes them more economical than electrical appliances. They can be used to supply hot water to several water intakes. All types of modern equipment are equipped with sensors for monitoring the safety of its operation. The disadvantages of gas water heaters include limited possibilities for their installation.
Gas main pipelines are not connected to all settlements in the country. Installation of equipment is carried out by experienced specialists after coordination of work with gas services. The operation of gas equipment is subject to a large list of safety requirements. The walls at the installation site of the geyser are upholstered with heat-resistant material or lined with ceramic tiles.
Types of geysers
Manufacturers offer customers geysers with various technical characteristics and a burner ignition system. It comes in 4 types:
- Manual. The water heater is ignited by a match, which is brought to the burner after opening the gas cock.
- Piezo. Columns with this type of ignition are equipped with a continuously burning igniter. At the right moment, he ignites the burner. Water heaters with piezo ignition, in comparison with other types of equipment, have a higher gas consumption rate.
- Electronic. The burners are ignited using cylindrical batteries or electric current.
- Hydrogenerator. The ignition of the burners is carried out by an electric generator, which is driven by a jet of water.
Gas water heaters produced by the industry differ in the type of burners installed on them. They are divided into 2 main groups: constant and variable power. The design features of the burners determine the way the water heating temperature is controlled. The power of the equipment determines its performance. It is expressed in liters of hot water heated in 1 minute. An important element in the design of water heaters are chimneys. According to their type, they are divided into devices with natural and forced hoods.
The main criteria for choosing gas water heaters
When making a purchase of household heaters, it is necessary to pay attention not only to their performance, but also to the pressure of gas and water in the network that exists at the installation site of the equipment.
Performance
The thermal power of the units is the main technical indicator. It affects the formation of the price of equipment. This means that it makes no sense to buy heaters with a performance that significantly exceeds real needs. Correctly calculated thermal power of the equipment will save money. In the technical documentation of gas water heaters, manufacturers indicate 2 indicators of their power:
- consumed- gas consumption;
- useful- Equipment efficiency.
Table 1. Types of heaters by thermal power
Attention! To work on 1 water intake, it is enough to install a geyser with a capacity of 11-18 kW. To provide water to 3 water intakes, a heater with a capacity of not less than 22 kW.
Gas and water pressure
The equipment manufactured by manufacturers is designed for certain indicators of water and gas pressure in the network. Their actual value is measured during the period of peak loads. It is better to entrust measurements of gas and water pressure to specialists. With constant low water pressure, it is recommended to purchase a column that has a water flow regulator.
Some owners of private housing construction increase the pressure in the plumbing system by forcing the flow with a pump. At low gas pressure, columns with a reducer are installed. Particular attention should be paid when buying water heaters from the manufacturer. Imported units must be adapted to Russian realities. In most regions of Russia, the gas pressure is about 13 mbar. In Europe, this figure is 20 mbar.
If you install a European heater that is not adapted to Russian gas pressure in the house, it will not gain the heat output declared by the manufacturer. Similar problems often arise with water pressure. Imported equipment intended for sale on the Russian market has a corresponding mark on the allowable pressure in the technical passport.
What to consider when choosing a column
When buying equipment, you need to pay attention to what material it is made of. You should not buy products from thin tin. Their service life is limited 3 years. The best speakers are made of copper. They have a high cost, which is offset by high efficiency and long service life.
The influence on the productivity of the equipment and the duration of its operation is exerted by the inner diameter of the tubes through which hot and cold water is supplied. Periodically they are cleaned of dirt and scale. Narrow tubes have to be cleaned much more often than wide ones.
Important! It is not recommended to buy speakers equipped with a plastic water storage tank. The filter and membrane inside the water heater need regular cleaning. Frequent opening and closing of the storage lid leads to abrasion of the threads on the plastic mouth of the barrel.

Which geyser is better to install in the apartment
In apartments of apartment buildings, gas equipment of medium and high power is installed. It can supply hot water to several water intakes at once. An important selection factor is the safety of gas equipment. For apartments, it is recommended to purchase water heaters with an automatic ignition system. It ignites the burners when the gas supply valve is opened. This ensures not only ease of use of the equipment, but also safety.
Entering the upper floors of apartment buildings, water loses its pressure. You can solve this problem by buying column with power modulating burners. They independently adjust to the actual water pressure in the pipes. Equipment equipped with a three-level protection system has the maximum degree of work safety.
These water heaters have the function of automatic blocking of the gas supply. It is triggered when there is a back draft or the burner flame goes out. Safety hydraulic valves help to avoid overheating of water. In the absence of ventilation in the apartment, it is recommended to purchase gas water heaters with an open combustion chamber. This will help to avoid the accumulation of exhaust gases inside the heater. They lead to overheating of the equipment.

An autonomous hot water system is extremely convenient. In many private houses and city apartments, gas water heaters are used for this. They have long and firmly entered the life of a person, fit perfectly into the interior of the kitchen, without spoiling it at all. The geyser gives the owner of the apartment a feeling of independence from the central heating supply, that is, annual preventive maintenance will not affect the availability of hot water in the household. In addition, the column helps to save a lot - the water is heated when it is really necessary, in the required quantities, it is possible to adjust the level of temperature rise.
However, devices installed earlier sooner or later run out of their resources, therefore, both for safety reasons and to increase the comfort of use, they have to be replaced. And many homeowners are planning the initial purchase of such a unit, deciding once and for all to get rid of dependence on the central hot water system. In both situations, the problem of choosing the optimal model will certainly arise. The diversity of the assortment presented for sale sometimes even makes this task difficult. Therefore, we hope that the rating of gas water heaters presented below will be a good help to the reader of this article.
Varieties of geysers and criteria for evaluating the chosen model
Geysers are divided according to several important criteria. You need to know this when studying the rating and choosing a device for a house or apartment.
In short, modern models of gas water heaters may differ in the following parameters and features:
- By type of ignition.
- According to the type of burners installed in the device.
- By type of combustion chambers
- The power and performance of the device.
In addition, gas water heaters are more often of a flow type, but there are expensive models that can also work in storage-boiler mode.
Types of ignition of geysers
Speaking about this characteristic, it should be noted right away that there will be no special differences in the operation of the device itself with different types of ignition. The difference is more about ease of use.
At the moment, there are models of speakers on the market with three different types of ignition - manual, piezo and electronic.
Prices for geysers
geyser
- Manual ignition already very rarely used - it can only be found in older models. Such columns are ignited with a match after the gas supply valve to the wick is opened. When igniting, it is necessary to act very carefully, because if the match is not brought up in time, a flash may occur with a large accumulation of gas.
- Piezo ignition. This ignition option functions on the principle of a conventional lighter. The mechanical force applied to the piezoelectric element causes an electrical discharge, accompanied by the appearance of a spark, from which the gas of the ignition wick ignites. To light a column that has a piezo ignition, you just need to press a special button. After a few seconds, hot water will come out of the open tap.
Water heater with electronic ignition - the battery compartment located below is clearly visible - Electronic ignition is the most convenient. True, for the operation of models with this function, an autonomous power supply is most often required - usually these are batteries placed in a special compartment.
Different models use different types of batteries to create a spark. The automation of the column reacts to the appearance of a current of water in the pipe, a glow plug is fired, which kindles a fire first in the wick-igniter, and then from it the flame is transmitted to the burner of the water heater. The installed batteries are enough for uninterrupted operation of the device for a year. There are models that do not require batteries - the necessary electrical potential for a glow plug is generated by an impeller driven by a stream of water open through a column.
Varieties of burners
Currently, manufacturers install various types of burners in different models of water heaters - with constant power or stepwise change, as well as modulation.
- Burners with constant or stepped power, require manual adjustment of the water temperature. They are very dependent on water pressure, so often when they are installed on the upper floors of tall buildings, problems with ignition and stable combustion can occur. Typically, such units have two control handles - separately for setting the amount of water flowing through the heat exchanger, the second - for adjusting the flame level.
- Modulating burners are installed in modern models. They are controlled by built-in automation, which provides heating of water to a certain temperature, regardless of its initial temperature and pressure in the plumbing system (of course, within the allowable range). Special sensors monitor all input and output parameters and regulate the optimal height of the flames.
It is also convenient that if several points of hot water supply are simultaneously involved in a house or apartment, then at all its temperature will be maintained the same. For example, if someone in the household is standing in the shower, and another turns on the hot water in the kitchen, the temperature of the water in the shower will not change. Automation will instantly take into account the increased consumption and make adjustments to the operation of the device.
Geysers equipped with similar automation with modulating burners are, of course, more expensive, but this is fully justified by the comfort of their operation.
Open and closed combustion chambers
Here everything should be clear from the name.
- An open chamber implies the intake of air necessary for the combustion process directly from the room. And the combustion products are diverted to the upper part of the body, where the branch pipe for connecting the chimney, which works on the principle of creating natural draft, is located. That is, the mandatory height difference between the heater and the chimney cap must be observed.
The disadvantages are obvious - it is required to take into account the additional flow of air into the room where the column is installed, the requirements for organization also increase sharply, since it is difficult to completely eliminate the ingress of combustion products into the room. In addition, the creation of a chimney for such a column is a rather large-scale and costly business, and in the conditions of a city apartment, if a common chimney is not provided for by the project of the house, it is completely impossible.
But for a private house, this is a completely acceptable solution, since the existing conditions, as a rule, allow building a chimney. Such speakers usually do not have a high price, and therefore for such conditions - a very attractive option.
- The closed combustion chamber does not come into contact with the atmosphere in the gas column installation room. A special coaxial chimney feeds the air necessary for combustion through one channel, and the second channel serves to remove combustion products directly to the street. That is, even in a city apartment, such a column can be installed quite well - it is enough to make an opening in the wall for the exit of a coaxial chimney. Of course, its placement is also regulated by certain rules, but usually they allow you to do this.
Geyser with a closed combustion chamber and a coaxial chimney discharged horizontally through the wall - By the way, a few words should be said about the once so popular small columns with an open combustion chamber that do not require connection to the chimney. The sad history of their operation is full of tragic cases of poisoning people with gas combustion products. Therefore, in many regions they are generally prohibited at the legislative level, even when all the necessary conditions are created - forced exhaust ventilation, which some owners simply forgot or were too lazy to turn on again.
Good advice: if such a device is still found on sale, and the sellers will assure you of its convenience and complete safety, it’s not worth the risk. Moreover, the very insignificant power and performance of such models is unlikely to give the expected increase in comfort, but there will be a lot of problems.
Power and performance of gas water heaters
These parameters of gas water heaters can be called the main ones, which you should be guided by when choosing a device, since it is on them that the overall ease of use and the full supply of family life with hot water depend.

All flow gas heaters according to this parameter can be divided into three groups:
- Low power devices, up to 15 kW. The performance of such columns is usually limited to 8÷9 liters of heated water per minute, which is enough for only one draw-off point. A water heater with such a capacity will be enough for a one-room apartment in which one or two residents live, where the water consumption is not too high, and the likelihood of simultaneous use of hot water in several currents is extremely small.
- Heaters with an average power of 16 ÷ 23 kW. These columns are capable of heating 10 ÷ 15 liters per minute, and are already able to support simultaneous consumption in two points, for example, in the kitchen and in the shower.
- Columns with a high power of over 23 kW heat up 15÷20 liters of water per minute, and this is quite enough for all household needs of a large family. However, such models already have impressive dimensions and a rather high cost, that is, their purchase should be justified. Otherwise, excess power, and during their operation, will lead to a significant inefficient increase in the cost of both gas and water.
It is quite possible to calculate the required power and performance of the gas column on your own. In a standard apartment, as a rule, two or three hot water intake points are installed - in the kitchen and two or one in the bathroom. In one minute, when using the shower, about 6 liters of water go out, and about 4 from the tap in the kitchen. If you simultaneously open the taps in the bathroom and in the kitchen, then the flow will be approximately 10 liters per minute. Of course, a small margin should be added to this, that is, focus on approximately 11 ÷ 12 l / min.
(The values of 6 and 4 liters mentioned above are very arbitrary, although they are considered sufficient. But some people like to use a large pressure of water both in the shower and when washing dishes. the number of liters at the optimum, from the point of view of the owners, water pressure).
Performance is always indicated in the column passport. But do not howl about an important nuance - it is shown for a nominal rise in water temperature by a certain number of degrees. For example, 10 l/min at Δt= 25 °C.
Performance is usually indicated with the expectation of a certain rise in water temperature, for example, as in this example, by 25 degrees But another indicator is overlooked - the temperature of the water at the inlet. Agree, there can be + 5 ° С in winter, and +18 ° С in summer. And at the exit it is always desirable to have a temperature of at least +40 ° C - it is considered comfortable for washing dishes and for water procedures.
Perhaps the table below will help:
| The temperature of tap water at the inlet to the column | The amount of water heated up to +40 ° C, depending on the power of the column (liters per minute) | ||||||||
|---|---|---|---|---|---|---|---|---|---|
| up to 3 kW | 6 kW | 8 kW | 12 kW | 15 kW | 18 kW | 21 kW | 24 kW | 27 kW | |
| 5 °C | 1,3 | 2,75 | 3,6 | 5,5 | 6,75 | 8,25 | 9,4 | 10,75 | 12 |
| 10 °C | 1,5 | 3,1 | 4,2 | 6,1 | 7,75 | 9,25 | 10,75 | 12,3 | 13.75 |
| 15 °C | 1,75 | 3,6 | 4,75 | 7,25 | 9,0 | 10,75 | 12,75 | 14,3 | 16.2 |
| 18 °С | 2,1 | 4,3 | 5,75 | 5,5 | 10,7 | 12,9 | 15,0 | 17,25 | 19.25 |
You can use a formula that takes into account the temperature difference at the inlet and outlet, the expected (or experimentally determined) flow rate and the coefficient of heat capacity of water. In order not to torment the reader with independent calculations, the author of the publication “concluded” this formula in an online calculator.
Geysers solve a common problem of lack of hot water supply in a house or apartment. These portable water heaters, with a minimum consumption of gas fuel, are able to provide hot water to residential premises of a considerable area. The main advantages of such devices are small dimensions, 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 opportunity to install, and models with electronic control or electric ignition need mains power. In addition, we are dealing with combustion products, so the installation of a chimney and ventilation is mandatory, 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 amount 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 want to heat the water intake at two points, then the model should have a rating of 20-28 kW. The most powerful water heaters (more than 29 kW) are able to provide residents of a house or apartment with hot water in large volumes.
- In case of problems with the supply of gas or water, the way out will be the purchase of storage gas water heaters. They are equipped with tanks in which a supply of warm water is stored. Thanks to the thermal insulation of the tank, it is possible to reduce gas consumption.
- 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 in the absence of flow. A thermal flame sensor shuts off the gas supply when the wick goes out. The draft sensor stops the gas supply when the draft in the chimney drops to a dangerous level. A useful option is the water overheating sensor, it not only prevents the formation of boiling water, but also reduces the amount of scale in the heat exchanger.
- Geysers are controlled differently. Most often, models of the middle 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 system. In open chambers, gas burns in the upper part of the column, from where it is immediately removed into the chimney. Somewhat more expensive, but sealed combustion chambers of a closed type look safer. The air supply, as well as the removal of exhaust gases, in such devices is forced. In addition to fans, coaxial chimneys are used in such models.
The most popular among buyers are heaters from Bosch (Bosch), Ariston and Mora (Mora). These European manufacturers are renowned for their reliability and performance. Domestic column Neva - excellent value for money. In the ranking, we will compare the best geysers in various price categories.
The best inexpensive geysers: budget up to 10,000 rubles.

1 Zanussi GWH 10 Fonte
Economical gas consumption. Suitable for apartments with low water pressure
Country:
Average price: 6 670 rubles.
Rating (2019): 4.9
In Russia, gas is cheaper than electricity, however, the issue of saving it is relevant for all homeowners. According to rough estimates, the cheapest liter of hot water is provided by the Fonte series geyser. This is a fully automated equipment with electronic ignition, the presence of which eliminates the constant burning of the wick: ignition is carried out immediately when the DHW tap is opened, and when the DHW tap is closed, the burner goes out on its own. This saves up to 30 cubic meters of blue fuel per month.
The water heater is famous for its low noise operation and the ability to work even at low pressure in the water supply - from 0.15 bar. A similar problem often worries residents of apartments on the upper floors, so this unit will help them out a lot. Its combustion chamber is open, so sufficient ventilation is required in the room. The design of the manifold prevents CO2 leakage and fully complies with EU standards, and combustion products are discharged through a chimney with a diameter of only 110 mm, so that the column can be connected to almost any chimney system.
The best geysers of the middle segment: budget up to 30,000 rubles.

Electric ignition quickly ignites the fuel, and the "gas-control" function eliminates any gas leaks.
In positive reviews, buyers talk about ease of operation, heating efficiency and excellent reliability, as the positive aspects of the Mora geyser. To install the device, it is not necessary to invite a specialist - detailed instructions in the kit will allow you to connect everything yourself. Overheating protection will prevent premature failure of the water heater, and temperature limitation will allow you to choose the optimal parameter for comfortable use of hot water. The disadvantages of users include not always triggered electric ignition and poor heating at low pressure.
Don't get busy independent connecting a gas column without relevant experience. Moreover, it is forbidden by law (any check of gorgaz = a fine). Connection of gas appliances should be carried out only by a specialist with a mandatory license (SRO) from his organization.
1 Ariston Fast Evo 11C
Modern burner design. Mains power for electronics
Country: Italy (made in China)
Average price: 13,890 rubles.
Rating (2019): 5.0
Gas water heaters equipped with constant power burners require manual temperature adjustment with each pressure change. Columns "Ariston", unlike them, 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, with the help of electric ignition, the power source of which is a 220V household network. If the user lives in a city apartment, and there are no particular problems with the supply of electricity, volatility is quite a good option to save on batteries.
However, not all reviews are equally positive. In some, they blame the failure of the radiator after 3 years of operation - they say, it leaked or burned out. To prevent this, experts recommend that future users carefully install the device and set it to pressure according to the instructions or use the services of a service center master with access to gas equipment. In this case, the column works correctly and absolutely does not require attention.
The best geysers for multiple taps (pressure water heater)
For those rooms where there are several hot water intake points, pressure water heaters will be the best option. Flow models may not be able to cope, since a sufficiently large amount of hot water is required at the same time, and in pressure vessels its level is constant (pumping is performed), which allows for a certain supply consumed by several receivers. The device is installed in a common riser, where distribution takes place.
5 American Water Heater PROLine G-61-50T40-3NV
The largest volume of the tank. ENERGY STAR® certified. Patented burner
Country: USA
Average price: 36,220 rubles.
Rating (2019): 4.1
AWH is the largest manufacturer of storage water heaters in the United States. Water heaters of the PROLine brand run on natural gas and are designed to prepare hot water not only in a private house, but also in a small production facility. The G-61-50T40-3NV is equipped with a 189L tank, the overall dimensions are 508x1450x508mm, so space for floor installation must be provided. It is noteworthy that gas burners manufactured by AWH Group are made of composite material and are characterized by a 33% reduction in nitrogen oxide emissions.
The domestic consumer, spoiled by technical sophistication, is at first surprised by the simplicity of the design: they do not even have a piezo ignition (in devices that are supplied to Russia from the same manufacturer under the Mor-Flo brand, the control unit has already been replaced, so the matches may not would need). However, the owners, who purchased this device about 15 years ago, claim that it does not exist more reliably. Only the electronic filling from Honeywell is worth something, inspires confidence and the inner coating of the glass-ceramic container. It is also important that the column is certified according to ENERGY STAR energy efficiency standards. i.e. its energy consumption is at least 20% lower than its counterparts.
4 Ariston S/SGA 100

Rating (2019): 4.2
The S/SGA 100 is a wall-mounted model with a large 95L water tank and is capable of providing multiple hot water outlets for a family of 2-4 people. It does not require a connection to the mains, it starts up with the help of piezo ignition, that is, by lightly pressing a special button. Despite the fact that the pilot burner maintains the flame constantly, the geyser consumes fuel carefully - up to 0.55 cubic meters. m./hour. Such profitability is explained by high efficiency and effective thermal insulation of the drive, made of high-density environmentally friendly polyurethane foam.
The weakest point of all boilers is the loss of tightness due to corrosion. To prevent its development, the inner surface of the tank is covered with heat-resistant enamel at the factory, additionally protecting it from corrosion with a magnesium anode. To increase the service life, it must be changed about once a year or two, depending on the hardness of the water. If you follow the operating rules, the device has been functioning flawlessly for many years - the model has existed since 2006, so there is a lot of evidence for this.
