Abstract

The invention discloses a heating device which comprises a shell and a fire cover, the shell is provided with a hollow cavity, a ventilation channel is arranged in the hollow cavity, at least two combustion areas with different combustion areas are arranged on the fire cover, and the ventilation channel is communicated with the fire cover. The invention further discloses the gas water heater. According to the heating device and the gas water heater, the first combustion area and the second combustion area which are different in combustion area are designed, the combustion area is small and the load is low when the gas is hot in summer, and water is not hot in summer; when big fire combustion is not needed in spring and autumn, the whole-area small fire combustion is achieved, the heat exchanger is heated evenly, the water temperature is fast and constant, the structure is simple, and manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to a heating device and a gas water heater. Background technique [0002] A gas water heater, also known as a gas water heater, refers to a gas appliance that uses gas as a fuel and transfers heat to the cold water flowing through the heat exchanger through combustion heating to achieve the purpose of preparing hot water. [0003] The gas water heater is mainly composed of the valve body assembly, the main burner, the small fire burner, the heat exchanger, the safety device, etc. It also includes the flue type water heater flue and the forced discharge device of the forced discharge type water heater. The valve body assembly controls the working procedure of the whole water heater, which includes water valve, air valve, micro switch and igniter, etc. When the water heater is installed, valves should be installed on the water inlet pipe, water outlet pipe and gas pipe. ...
