How to choose a gas water heater?
The main criteria to be evaluated when choosing a water heater:
- Power. The parameter determines the water capacity of the device. The higher the power, the more points you can supply hot water.
- Inlet pressure. It affects the ability to supply water at a low head. Many modern models that the water supply is possible at a low flow.
- Safety. Columns are equipped with a system of protection against overheating and freezing, as well as a sensor to turn off the unit and stop the gas supply in case of a leak.

Advantages and disadvantages of gas columns
Among the advantages of a gas water heater can be distinguished:
- Providing hot water in unlimited quantities;
- a wide range of equipment at budget prices;
- undemanding to the water pressure in most devices;
- compact size allows you to install the equipment in a small apartment;
- possibility of repair in case of breakage of parts;
- Significant savings, since gas is cheaper than electricity.
The disadvantages of the gas water heater are less:
- for safe operation of the equipment is required to ensure the supply of fresh air and the organization of drainage of exhaust gas;
- The need for regular maintenance;
- the cost of the project documentation for the installation of the column.
The principle of operation of the gas water heater
Modern columns are improved, so the principle of operation is much simpler than in older models. To start it, you need to open the faucet tap.
Immediately after this:
- water enters the unit, opening the valve for gas supply;
- the flame is ignited automatically;
- hot water is directed to the mixer;
- the waste product is discharged through the chimney or coaxial pipe;
- After closing the valve, water and fuel supply is stopped.
Types of combustion chambers
There are two types of combustion chambers in a column:
- Open. To ignite the gas is used air from the room, the intake of which is carried out through the hole at the bottom of the unit. Waste gas is extracted through the chimney in a natural way.
- Closed. The combustion air is drawn in from the outside through a coaxial chimney and the smoke is exhausted by means of a forced exhaust hood.
What is better - a gas water heater or an electric water heater
Unlike an electric heater water heater provides instant hot water.
No time is needed for heating - the water is heated instantly. Installation of equipment requires a minimum of space in contrast to the boiler.
Disadvantage of the gas water heater compared to the electric water heater is that the water temperature decreases when it reaches several points of intake.
What is flame modulation
Flame modulation is an option on modern water heaters to select the desired water temperature.
The power of the flame in this case is automatically adjusted to the water head.
The advantage of models with flame modulation is that they supply water with the desired parameters even at a low water pressure.
