Solar water heater with gas water heater

Abstract

The invention relates to a solar water heater with a gas water heater, which includes a solar water heater and a cold water inlet pipe, and is characterized in that it also includes a gas water heater, a solenoid valve, a three-way valve, a controller, a temperature probe and a water mixing valve, wherein the solar water heater passes through three The through valve is connected with the cold water inlet pipe, the outlet pipe of the solar water heater is connected with the inlet pipe of the gas water heater through the three-way valve, the solenoid valve is set on the cold water inlet pipe, the controller is set in the gas water heater, and the temperature probe is set in the gas water heater. On the water outlet of the water inlet pipe, the controller is electrically connected with the temperature probe and the solenoid valve respectively; the outlet pipe of the gas water heater is connected with one water inlet of the water mixing valve; Its beneficial effects are: the invention realizes that the solar water heater has hot water immediately when it is turned on, and can realize a stable supply of hot water around the clock, while maximizing the use of solar energy, the consumption of gas is greatly reduced, and a comfortable, economical, energy-saving and environment-friendly environment is realized. combined.

Description

technical field [0001] The invention relates to a solar energy utilization technology, in particular to a solar water heater with a gas water heater. Background technique [0002] The realization of the function of solar water heater basically depends on the weather, so the stability of its hot water supply is often not guaranteed. Therefore how to make the solar water heater continuously and comfortably use becomes a problem to be solved. The most common method at present is to install an auxiliary electric heater in the solar water heater water tank, but because the general solar water heater is installed outdoors and has a relatively large volume, the power consumption is relatively high. And when common solar water heaters are in use, there is generally a certain amount of cold water in the outdoor pipelines, which cannot be realized to have hot water immediately when turned on. [0003] The technology of gas water heaters is relatively mature and can provide hot water...

AI Technical Summary

Problems solved by technology

At present, the most common method is to install an auxiliary electric heater in the solar water heater tank, but because the general solar water heater is installed outdoors and the volume is relatively large, resulting in high power consumption

Moreover, when ordinary solar water heaters are in use, there is generally a certain amount of cold water in the outdoor pipes, and it is impossible to realize instant hot water.
