Control method of condensation type gas water heater and condensation type gas water heater

The invention provides a control method of a condensation type gas water heater and the condensation type gas water heater, and the control method comprises the following steps: acquiring gas flow to control the opening degree of a proportional valve; operating parameters of the atomizer are adjusted according to the opening degree of the proportional valve; the atomizer is controlled to be opened and closed according to the operation condition of the water pump. In the using process, the opening degree of the corresponding proportional valve is controlled through the gas flow, and the operation parameters of the corresponding atomizer are controlled through the opening degree of the proportional valve, so that the atomization efficiency of the atomizer is matched with the gas flow, and the operation efficiency of the atomizer is improved while a condensate water drainage pipe does not need to be arranged. By means of the technical scheme, residues of condensate water on the condensate water receiving contain
