FIELD: heat-power engineering; heat supply systems. SUBSTANCE: hot-water boiler house has at least one hot-water boiler, water-to-water heat exchanger, make-up water vacuum deaerator with feed water, heating agent and deaerated make-up water pipe lines; last pipe line is connected to circulating pipe line through storage tank and make-up pump. Hot-water boiler, water-to-water heat exchanger and circulating pump are interconnected by means of pipe lines forming closed circulating loop. Heating agent pipe line of vacuum deaerator is connected to supply pipe line through additional water-to-water heat exchanger which is connected to pipe line of closed circulating loop at outlet of hot-water boiler and before circulating pump. EFFECT: enhanced reliability and economical efficiency. 1 dwg
