Application method of constant-temperature gas water heater

Abstract

An application method of a constant-temperature gas water heater includes: setting needed hot water temperature in the gas water heater firstly, when using hot water, automatically switching on an electric check valve(17) by a gas water heater microcomputer controller (12) and switching off an automatic electric cut-off valve(II8), water flowing through a pipeline(A) and the electric check valve(17) to a water heater exchanger(9), igniting automatic heat supplying to needed temperature by the gas water heater to reach hot water point to use, automatically switching on the automatic electric cut-off valve(II8) by the gas water heater microcomputer controller (12) and switching off the electric check valve(17) when a temperature sensor (13) on a water inlet pipeline senses the solar energy hot water temperature is higher than needed temperature. By the application method, when the energy water temperature can not reach or exceed the requirement, constant temperature hot water for bathing can be supplied, and bathing comfortableness can be improved.

Description

technical field [0001] The invention relates to a method for using a gas water heater, in particular to a method for using a constant temperature gas water heater dedicated to solar energy complementation. Background technique [0002] At present, due to climate and weather reasons, solar water heaters cannot meet people's all-weather use when the light is insufficient, and also have the disadvantage of slow water output. In addition, the existing solar energy and electric heating complementary water heaters have the disadvantage of long waiting time for heating, and in order to use a small amount of hot water, the water in the entire water tank must be heated to the required temperature, which wastes energy and cannot satisfy people. requirements. In addition, when the sunlight is sufficient, the solar water temperature is high, and users often cannot get hot water at a constant temperature that meets the requirements. Contents of the invention [0003] The purpose of t...

[0002] At present, due to climate and weather reasons, solar water heaters cannot meet people's all-weather use when the light is insufficient, and there are also disadvantages of slow water output.

In addition, the existing solar energy and electric heating complementary water heaters have the disadvantage of long waiting time for heating, and in order to use a small amount of hot water, the water in the entire water tank must be heated to the required temperature, which wastes energy and cannot satisfy people. requirements

In addition, when the sunlight is sufficient, the solar water temperature is high, and users often cannot get hot water at a constant temperature that meets the requirements.
