Abstract: FIELD: power engineering. 
     SUBSTANCE: invention relates to power engineering, namely, to method of water-heating device operation. Proposed method consists in feeding fuel used as a mixture of natural gas and hydrogen and air into combustion chamber of water heating device. Mixture is burnt in combustion chamber. Water is heated in the boiler of the water heating device by passing the combustion products of the fuel-air mixture through the volume of water placed in the boiler. Then, the combustion products of the fuel-air mixture are cooled down and the cooled combustion products are discharged into the atmosphere. At that, air is pre-cooled to temperature lower than temperature of the medium surrounding the water heating device. Volume fraction of hydrogen in fuel makes 20-25%. Fuel-air mixture pressure is created in the combustion chamber of not less than value of pressure of water volume in boiler of water-heating device. Cooling of combustion products of fuel-air mixture is performed by creation of countercurrent flow of cooled air and combustion products of fuel-air mixture without their mixing.
