Central heating system of solar water heater

Abstract

The invention discloses a central heating system of a solar water heater, which comprises a water tank connected with a heat collector and a sensor for testing water temperature and water amount, wherein the heat collector is connected with a plurality of non-bearing water tanks which are connected with bearing water tank through pipelines; the bottom of the bearing water tank is connected with a hot water pipe and a heating return pipe; the hot water pipe is connected with a shower head of each bath; the heating return pipe is connected with a heating strip of each heating room; the upper part of the non-bearing water tank is connected with a temperature control circulating pipe; and both the hot water pipe and the heating return pipe are communicated with the temperature control circulating pipe. The heating system is automatically controlled, safe and reliable; the outside of the bearing water tank connected with the user terminal is provided with an auxiliary heating device to ensure the stability of the water temperature; the water can be used at any moment; at the same time, the heating system avoids the process of exhausting cold water before using hot water, and saves water resource and user time.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a solar water heater centralized heating system capable of heating a large area. Background technique [0002] The current domestic solar water heaters occupy a large area for the first time, and the pipeline installation is messy and not standardized enough, which affects the appearance; for the heating system of the water heater, it is more troublesome, and it needs to be filled manually, and the opening and closing of the water inlet of the water tank is manually controlled. And must decide whether it has hot water to use according to weather condition, also must emit a large amount of cold water earlier during use, wasted manpower and wasted cold water simultaneously. Contents of the invention [0003] The invention provides a centralized heating system for solar water heaters that can collect heat in a large area and keep water temperature stable at any time and can provide heat for...

[0002] The current domestic solar water heaters occupy a large area for the first time, and the pipeline installation is messy and not standardized enough, which affects the appearance; for the heating system of the water heater, it is more troublesome, and it needs to be filled manually, and the opening and closing of the water inlet of the water tank is manually controlled. And it must be decided according to weather conditions whether it has hot water to use, and a large amount of cold water must be released earlier when using it, which wastes manpower and cold water at the same time
