In the conventional heating systems such as a gas boiler and an air source heat pump, when heating is performed, no matter whether the gas boiler burns or not, the gas boiler heating circulating water pump is always running, and circulating water needs to pass through a main heat exchanger in the gas boiler. After the water outlet temperature of the gas boiler reaches the use requirement, the combustion can be stopped, but the heating circulating water pump still operates all the time. At this time, the circulating water which is always operated passes through the main heat exchanger of the gas boiler and needs to overcome the internal resistance of the gas boiler, so that the electric energy of the water pump is needed to be consumed; the circulating water continuously passes through the gas boiler, so that the continuous heat dissipation of the gas boiler to the outside is increased, and the waste of energy sources is caused; meanwhile, when combustion heating is not performed during heating operation, circulating water always passes through the main heat exchanger of the gas boiler, so that the possibility of abrasion and blockage of the main heat exchanger is increased; in addition, the continuous operation of the heating circulating water pump and the circulating water passing through the gas boiler can generate noise, so that the noise level in the operation of the equipment is increased.
