Such equipment as gas water heater will provide you with reliable and safe operation, as well as economy and efficiency of heating.
Before you buy gas equipment, determine your main needs.
1) Presence or absence of a chimney.
This depends on the type of column (flue, turbo, flueless).
Chimney gas columns are equipped with a chimney, usually with a diameter of 110 mm, and they need to be connected to a stationary smoke removal system. Can work from ordinary 1,5 V batteries.
Turbocharged gas columns do not require the presence of a stationary chimney, but are equipped with a forced system - a turbine. Such equipment requires a 220 V power supply.
Chimney-free gas columns operate from two 1,5 V batteries, without a chimney and coaxial pipe. Their advantages are compactness and the ability to work at low pressure in the water supply system.
2) Estimated volume of hot water consumption.
After all, the power of the gas column is the main parameter that reflects the amount of hot water. Columns are produced with a capacity of 12 to 30 kW.
To calculate the approximate required power, you need to know the performance.
To do this, we divide the power of the purchased column in half. For example, 16 kW / 2 = 8 l/min, we get a capacity that will provide heating of water by 30 degrees. Approximately, this is enough for one person to take a shower.
If your family is large and you need several water intake points (in the kitchen and in the bathroom), then consider the option of a more powerful gas column, for example, this 24 kW.
So, you have decided on the chimney and power, now you should pay attention to the other nuances.
First, it's safety. It is desirable that a safety system that turns off the equipment in the event of any malfunctions is built-in. That is, there must be flame and draft sensors, overpressure protection, and antifreeze protection.
Secondly, heat exchanger protection. It is desirable that it be copper, the presence of filters at the water inlet, as well as a sensor to protect against overheating of the heat exchanger.
Third, choose speakers that can work stably at low water pressures.
Fourthly, the availability of service centers that you will need in the future to perform equipment maintenance.
Fifth, functionality (for example, a very useful "winter-summer" function), compactness and beautiful design.
Having spent a little time to study and select equipment, you will purchase a high-quality gas instantaneous water heater that will provide you and your family with hot water efficiently and for a long time.
