Abstract
The utility model relates to a dual-water-pump gas-fired heating and hot water boiler, which comprises a heating system and a water line system. The heating system is mainly formed by a fuel gas inlet pipe, a fan, a combustor, a heat exchanger and a flue gas exhaust pipe. The water line system is mainly formed by a heating water return pipe, a heat exchanger water inlet pipe, a heat exchanger water outlet pipe, a heating water outlet pipe and a safety valve. The dual-water-pump gas-fired heating and hot water boiler is characterized in that a dual-water-pump circulating water return structure is arranged in the water line system and comprises two circulating water pumps which are respectively installed on the heating water return pipe and the heating water outlet pipe. Since two low-power water pumps are used, the effect of a high-power water pump is reached, the system pipeline is optimized, the lift and the flow are higher, the cost is lower and the problems that the power of the external water pump is not matched with the power of the heating boiler water pump, the working noise is high and the like are solved.
