The work is devoted to solving the problem of the lack of draft of the existing chimney when operating hot water boilers at full capacity. Thermal and aerodynamic calculations were performed. Thermal calculation was carried out with diff erent loading of hot water boilers and the number of operating burners. The options for the operation of boilers according to the regime map and test protocols are considered. In the aerodynamic calculation for the sections, the resistance of the gas ducts was determined, the chimney was calculated. A fl ue gas pump is installed to remove combustion products from hot water boilers. This will ensure the parallel operation of two hot water boilers over the entire load range.
