Gas water heaters for apartments and houses: reliability and quality rating

Which gas water heater is better to buy?

The choice of heater depends on the number of water points that the boiler will serve and the required volume of hot water, taking into account the needs of the family. But there are a number of technical characteristics that you should also pay attention to when purchasing.

The power of the geyser determines how much hot water and to how many points it can supply:

• Up to 20 kW – one consumer, 11 l/min;
• From 21 to 25 kW – for two points, up to 15 l/min;
• From 26 to 31 kW – for three points, more than 16 l/min.

Combustion chamber type. Inexpensive models use open-type cameras. In them, the combustion of the flame is supported by air coming directly from the room, and combustion products are discharged through the chimney.

When choosing such equipment, you will need to organize fresh ventilation (or simply keep the kitchen window slightly open).

Closed-chamber water heaters use air from outside to support the flame. Soot and smoke are discharged there. You can install such speakers even in closed rooms without windows.

The geyser should be equipped to the maximum with all available security systems. At a minimum, it will need protection against overheating and automatic gas shutoff in the event of a lack of water or an extinguished burner.

You can learn about other parameters for choosing gas pumps from our article. Now let’s look at the best models of water heating equipment that have recently entered the market.

Types of geysers

Gas water heaters can be divided into two types.

1. Gas instantaneous water heater. It is an ordinary column, known to us since the middle of the last century. Cold water passes through the heat exchanger, which is heated almost instantly using a burner. Exhaust gases are discharged to the street through the chimney. The device is very compact, consumes gas economically and can operate indefinitely for a long time.
2. Storage gas heater. This is the same electric water heater, only running on gas. It is equipped with a tank into which water is collected and heated to the optimal temperature. Tank capacity can vary from 50 to 500 liters. Such a unit has impressive dimensions and is quite expensive, so it has not taken root in our small-sized apartments and is not popular even among owners of private houses.

The best flow-through geysers with an open chamber

Water heaters with an open combustion chamber are installed in rooms with a chimney and good ventilation.

As a rule, these are the simplest speakers without automatic controls that do not need to be connected to electricity. However, among them there are also more advanced devices.
