FIELD: heating systems. ^ SUBSTANCE: invention is meant for water heating and can be used for heating and hot water supply. Electric boiler house includes electric boilers, storage tanks of heating and ventilation load which are connected to the above boilers and have the possibility of being operated in a closed circuit, hot water supply storage tank, increasing and circulation pumps and main-line pumps, hot water heater, shutoff valves, anti-scale magnet devices and automatic control devices forming the circuits of heating and ventilation load and hot water supply load. Heating and ventilation load circuit and hot water supply load circuit are made separately; heating and ventilation load circuit is equipped with a three-way switching device the inlet whereof is connected to the network pipeline of return heat carrier; one of the outlets is connected to electric boilers, and the other one is connected to the lower zone of storage tanks. Network pipeline of return heat carrier is connected to the lower zone of storage tanks with an additional line equipped with charge pumps. ^ EFFECT: improving technological reliability and informativity of electric boiler house and reducing labour input of operation thereof. ^ 5 cl, 2 dwg |
