Operating principle

The operation of gas equipment is carried out according to the following algorithm:

• after opening the tap, the required coolant enters the heat exchanger, the heating burner is ignited from the igniter;
• water passes through the coil and is heated with the help of heat that is released in a large volume during the combustion of fuel (rapid heating occurs due to heat transfer at a tremendous speed, which is associated with the high thermal conductivity of materials);
• exhaust gases are released by natural draft in the chimney or forced draft.
