The water heating equipment includes the water boiler with water-jacket and furnace, the outgoing smoke heat utilization device consisting of the contact condensation heat exchanger, the condensate circulation contour, and the water-water heat exchanger for water heating as well as the smoke exhaust device at the utilization device exit orifice. This equipment (fig.1) additionally is fitted with the hot gas circulation contour with the hot gas centrifugal purifier, the smoke exhaust device with gate valve, in addition the hot gas centrifugal purifier is equipped with cylindrical cooling housing with water-jacket, the tangential hot gas supply pipe in the upper part of the housing, the hot recirculation gas supply pipe in the lower part of the housing and the axial hot purified gas outlet pipe. The tangential supply pipe is connected to the upper part of the furnace. The smoke exhaust inlet is connected to the hot gas recirculation supply pipe, but the smoke exhaust outlet is connected to the lower part of the furnace. The gate valve is installed at the smoke exhaust outlet. The hot gas heat utilization device is connected to the axial outlet pipe, however the hot gas centrifugal purifier water-jacket, the water-water heat-exchanger for the network water heating and the water boiler water-jacket are consecutively interconnected.<IMAGE>
