The principle of operation and the device of the gas column: general information
First you need to understand the types of flow household gas water heaters. They can be with an open combustion chamber or turbocharged (with a closed chamber). Despite the design differences, they have the same purpose - the rapid heating of running water passing through them. The principle of operation of such devices is simple. Cold water passes through the coil, heated by a gas burner, and then flows to the consumer. The outflow of combustion products is carried out by natural ventilation (open combustion chamber) or forcibly - using a fan that blows air into the chamber (turbocharged models).
GOOD TO KNOW!
The cost of devices with a closed combustion chamber is higher.
How to make the right choice when buying a water heating gas water heater: expert advice
When choosing a gas water heater, several aspects play a role, but the main ones are the answers to the following questions:
- for which room the water heater is purchased (apartment or private house);
- how many points of water intake are planned to be connected to the device.
This is the main thing to decide before purchasing. There are also secondary questions, but more on them later.
How to choose a gas water heater for an apartment: expert recommendations
The first thing to pay attention to is the method of removing combustion products. If ventilation in the apartment does not work perfectly, a heater with an open chamber will not work. Good traction is needed for it to work. Otherwise, combustion products will accumulate inside. As a result, the temperature will begin to rise and the emergency sensors will give the command to shut off the gas supply. And this will happen periodically. Therefore, it is better to purchase turbocharged models with a closed combustion chamber for an apartment.
Which gas water heater is better to buy for installation in a private house
For private houses, a closed combustion chamber in a water heating device or an open one does not matter. Indeed, it is easy to make good ventilation in a cottage, in contrast to an apartment building. The only question that will have to be solved, answering the question of how to choose a gas water heater for a private house, will be the choice of the power of the device. We will talk about this now.
Which gas water heaters are better for one, two and three points of water intake
Let's start by defining the number of people living in the house. For example, if 1-2 people live, then even 2 points of water intake can be considered as one. After all, two people can always agree on who needs a crane at one time or another. In this case, a gas water heater with a capacity of 17-20 kW is sufficient. For a city apartment in which 3-4 people live and 2-3 points are equipped, a device with a capacity of 20-26 kW is quite suitable. Well, if more than three water intake points are equipped and households love water procedures, powerful equipment is needed - 26-31 kW.
HELPFUL INFORMATION!
The cost of a device does not always depend on its power. Often the main overpayment goes “for the brand”. Therefore, you should not chase the promoted brands. It is easier to find a cheaper option that will not be inferior in quality.
The best gas instantaneous water heaters, depending on the manufacturer: expert opinion
There are a lot of manufacturers of such equipment - it's easy to get confused in a huge number of model names. That is why the editors Tehno.guru gathered the opinions of experts about which models are the best from this or that manufacturer. Today we will try to present something like a rating of the reliability and quality of gas water heaters, having considered only one best model from each of the manufacturers. We hope this information will help our dear reader, if necessary, make the right choice.

A widely known brand in Russia and the world - "Ariston"
According to experts, the most reliable and high-quality model from the line of Ariston gas water heaters is Ariston NEXT EVO SFT 11 NG EXP. Despite the rather high cost, it is she who is considered optimal for installation. Many users note shortcomings in it, but this is all from ignorance and unwillingness to study the instructions. All device settings are test, which indicates the need for self-adjustment of the device for the supplied gas.
power, kWt | Productivity, l / min | Gas consumption, m³ / h | Max t water, ° С | Dimensions, mm | Weight, kg |
19.58 | 11 | 2.2 | 70 | 330×550×167 | 12 |

Swedish concern "Electrolux" - time-tested quality
The most interesting model from the line of gas columns "Electrolux" - "GWH 10 NanoPlus 2.0". The power of the device is not the maximum possible, but it is quite capable of maintaining a given temperature while simultaneously turning on four points of water intake. It is not picky about the pressure of gas and water. It is this, according to experts, that ensured the popularity of the model.
power, kWt | Productivity, l / min | Gas consumption, m³ / h | Max t water, ° С | Dimensions, mm | Weight, kg |
20 | 10 | 2.28 | 75 | 330×550×190 | 8.08 |
In addition to natural, this gas water heater is capable of operating on liquefied gas. In this case, the consumption will be equal to 1.67 kg / h. Let's get acquainted with the opinion of users.

"Bosh" ("Bosch") - one of the leading manufacturers of construction and household equipment
The bosh WRD 15-2G gas water heater is interesting in that it does not require batteries or network connection for piezo ignition. Everything is powered by a generator rotated by the pressure of water. However, the capacity of 15 l / min is useless for the average family of four, and the overpayment is significant. Therefore, experts advise to stop at the "Bosh WR 10 2p" model.
power, kWt | Productivity, l / min | Gas consumption, m³ / h | Max t water, ° С | Dimensions, mm | Weight, kg |
17.4 | 10 | 2.1 | 60 | 310×580×220 | 11 |

The best column for the type of combustion, taking into account the hood
In fact, there is practically no difference between an open and a closed combustion chamber. However, experts advise purchasing devices with a closed chamber - they have fewer ventilation requirements and their efficiency is slightly higher. This means that the gas consumption will be lower at the same temperature indicators and productivity. Of course, the cost of this type of device is slightly higher, but the difference pays off in savings rather quickly.
Conclusions of experts on the best models based on cost
It's no secret that prices for any product can be divided into three categories - budget, medium price category and premium class. Here are some examples of the best in each of these categories.
Geysers of the budget category: which one is better
Experts call "DELTA DL-8WB1 / 1" the best instantaneous water heater of the budget category. The cost of the model is negligible compared to analogs from other manufacturers. Let's see what are its characteristics.
power, kWt | Productivity, l / min | Gas consumption, m³ / h | Max t water, ° С | Dimensions, mm | Weight, kg |
16 | 8 | 1.55 | 65 | 320×520×158 | 10 |
DELTA DL-8WB1 / 1

This is a device with a closed combustion chamber. That is why its efficiency is 93.5%, which is quite a lot.
Summarize
There is no doubt that the gas water heater is indispensable in rural areas, in the country, in the private sector. However, many install such devices in city apartments, abandoning centralized hot water supply. According to them, the use of a gas water heater is much cheaper. There is no reason not to trust them. In any case, the choice of such equipment should be deliberate and balanced. Even when purchasing an inexpensive model, do not be lazy to go online and read reviews about it.
