The check valve 32 is provided to ensure that the water flow direction of the main pipe of the water supply main pipe 30 is in the direction of the heating terminal equipment 50.
According to the dual-energy heating system, the heat pump 10 and the gas wall-mounted boiler 20 are combined, the water outlet temperature of the heat pump 10 is acquired through the first temperature sensor 31, when the water outlet temperature of the heat pump 10 cannot meet heating requirements, the gas wall-mounted boiler 20 is controlled to be started through the temperature controller 21, so that the heating system can use the heat pump 10 to the maximum extent on the premise of ensuring a heating effect, the purpose of saving energy is achieved, and meanwhile, under extremely cold weather, the heat source of the gas wall-mounted boiler 20 is supplemented, and the heat supply stability is still ensured.
