FIELD: heating; power engineering.
SUBSTANCE: invention relates to heat power engineering and can be used in individual heating systems for residential buildings. In the heating mode, the combustion products are heated in a heat exchanger by a heat transfer medium that moves naturally through the outlet, a three-way valve and pipes respectively into the heating circuit and the tank, heating at the same time heating appliances and heat exchanger for hot water supply, after which the cooled down return to the input of the heat exchanger heating through the pipes. When the tap is open, the water heated in the heat exchanger rises due to the lower density of the hot water riser, and the cold water in the riser is lowered into the heat exchanger, resulting in a constant circulation of water, heating the riser itself and the presence of water in the latter with a temperature close to the required value. When opening the water tap, a hot water sensor is triggered, as a result of which the three-way valve switches the flow of the heat carrier heated in the heat exchanger through the outlet to the vessel for intensive heating by means of a heat exchanger for hot water supply of cold water entering the latter and then into the riser from the main.
EFFECT: increased operational characteristics of the hot water supply system.
