1. Bosch WR 10-2P
This device has a power of 17.4 kW, due to which its productivity is up to 10 l / min, and the maximum heating temperature is up to 60 degrees. Adjustment is made by convenient mechanical switches.
Reliable protection against leaks is achieved due to the increased operating pressure range – from 0,1 to 12 atm. But for safe operation, an additional air duct is required, since the device is equipped with an open type combustion chamber.
An important point – this model uses piezo ignition, the principle of operation of which is based on the ignition of fuel by a silicon spark. According to experts, this type of “ignition” is more reliable than electric, because. in the latter, burnt components often fail. Although he deprives the device of “automatics”.
Also, from the advantages of this device, it is worth noting the relatively small dimensions and ease of installation. The gas and water supply is from below, so you can connect the necessary hoses and hang the device on the wall yourself without any problems.
There are two versions of this column on the market – P23 for natural gas from a gas pipeline and P31 for liquefied gas from a cylinder. Thus, the device can be used both in an apartment with centralized gas supply, and in the country.

5. Hyundai H-GW1-AMW-UI305
This flowing gas water heater has a power of 20 kW and a capacity of 10 l / min. It is started with the help of an electric ignition, powered by batteries. The stability of temperature and gas flow is controlled by the built-in electronic unit, and a convenient display will help you keep track of the set parameters. It also helps you find and fix problems.
The body of the device is made of enamelled steel, and the burner is made of stainless steel. The heater is made of copper with a wall thickness of 0.5 mm. It is important to note here that gas water heaters with copper heat exchangers are preferable for apartments or houses with a constant consumption of hot water, because. they conduct heat as quickly as possible and thereby reduce the heating time.
This model is available in two colors – black and white. This will allow you to fit the water heater into almost any design.
Advantages and disadvantages
6. Neva 4510-M
This domestic-made water heater is an excellent choice in terms of price / quality ratio for those who are considering budget options. It is universal due to the fact that it can work both from natural (centralized gas pipeline) and from liquefied gas (from a cylinder).
The power of 17.9 kW provides a capacity of 10 l / min, which is suitable for both an apartment and a whole house. In addition, the device is equipped with several points of water intake, which allows you to simultaneously use it in different rooms – for example, a bathroom and a kitchen. In addition, like many analogues, the device has a bottom line of communications, which simplifies installation.
Quiet operation, a thermometer for temperature control on the front panel, electric ignition from batteries can also be noted from the pluses. Moreover, a smart electric ignition system consumes a minimum of energy, which will free you from the need to frequently change batteries. The column starts at a minimum pressure of 0.1 atm, which means you should not be afraid of a weak water pressure.
Of the minuses, perhaps, only the low quality of materials should be singled out, which affects the service life of this water heater.
Advantages and disadvantages
7. Bosch WRD 13-2G
The model is one of the most powerful in our top – 22.6 kW. Thanks to this, its productivity reaches as much as 13 l / min, and this compensates for the increased (relative to many analogues) price. The column turns on at a pressure of 0.35 atm, which allows it to work even at low water pressure.
The device can operate both from a centralized gas pipeline and from a liquefied gas cylinder, so it can be used in a country house where there are problems with communications. In addition, the pluses include a high-quality security system that turns off the water heater if its temperature becomes higher than the permissible one.
As for the minuses, the main disadvantages of this model are considered to be a noisy hydro generator, as well as an inconvenient location of inlets and outlets for gas and water. The device has an open type combustion chamber, which requires an additional air duct.

How to choose a geyser
What to look for when choosing the best gas column?
Power
As a rule, buyers choose flow type geysers. Their average productivity is about 10 l / min, which is enough to provide hot water for both an apartment and a country house.
True, it is worth paying attention to the number of water points – if you need to “let” hot water into several rooms, the column should have several outlets.
Management
Geysers have two types of fuel ignition – electric ignition and piezo ignition. The first one is more convenient due to the fact that it automatically turns on the device when the hot water tap is opened. The second is basically launched using a special button.
It should also be noted that there are two types of electric ignition – from batteries and from the mains. In the first case, you save on electricity, but you will need to periodically change the batteries. The second option involves connecting to the mains, which complicates the installation of equipment. But the option powered by 220V is not always suitable for giving, where there are problems with communications.
Dimensions
If, when choosing a water heater, you settled on a gas water heater, then you should understand that it will take a certain place in your apartment or house. Unlike electric flow heaters, such devices are unlikely to be disguised as a kitchen cabinet, so before buying, you need to decide in advance on the place where the column will be installed. But most models will fit into the interior without any problems due to the stylish design.
Economy
A geyser is an ideal option if savings are a key factor for you when buying.
Whatever consumption is declared by the device, it is worth remembering that in any case it will be cheaper to use such a water heater than an apparatus powered by electricity. It does not play a special role, whether it will be natural gas or liquefied fuel from a cylinder.
Additional features
When choosing a column, pay attention to the possibility of connecting the device to a liquefied gas cylinder. In this case, the device will be mobile. If necessary, it can be transported and installed in a country house where there is no centralized gas pipeline.
An electronic control system with a display will also be a nice addition, thanks to which you can not only easily adjust the set temperature, but also monitor (and even correct) possible errors in the operation of the device.
Checklist when buying the best geyser
- If you choose a device for a summer residence or a country house without communications, pay attention to models powered by liquefied gas cylinders.
- When choosing a geyser, you need to understand the capabilities of your water supply. When buying a device with a capacity of more than 13 l / min, make sure that the water pressure in the apartment / house will allow you to use the declared power.
- If you have frequent power outages at home, then you should purchase a column with electric ignition from batteries or with piezo ignition. Otherwise, with a power outage, you will lose hot water.
