How to solve the problem when a home solar water heater is hot and cold for a while?

The reason is:\x0d\The water temperature is too high. You need to refill the water in time to lower the water temperature. This problem can be eliminated if the water temperature is below 80 degrees. If possible, purchase and configure a water mixer with a constant temperature function, the price is generally more than 200 yuan. \x0d\Tap water pressure is unstable or too low and should be avoided during peak periods;\x0d\The spray hose is aging and has internal expansion and distortion, or there is a blockage in the nozzle. Replace the nozzle hose. clean and clean the nozzle, or replace it with a new one.

What causes the solar water heater to become hot and cold while bathing?

Slowly adjust the cold water valve. Let it sit for a bit, then wait a while. If it's hot, wait a little longer and adjust it a little more. Why do you have to wait for amoment after each adjustment? The water must be mixed and the unmixed water must be drained.

The solar water heater is a heating device that converts solar energy into thermal energy, heating water from low temperature to high temperature to meet the use of hot water by people in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the domestic market share. Household evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum heat collecting tubes which use the principle of hot water floating. Andcold water flows to cause microcirculation in the water. Get the hot water you need.

In terms of using solar thermal energy, the distance between the most dispersed collectors and the heat accumulators is relatively long, the thermal conduction system therefore remains essential. Thermally conductive materials mainly include heat-conductive flow materials and heat-conductive flow pipe materials. Additionally, thermal storage materials can also be used as heat-conducting flow materials in liquid or gas phase states. International research tends to use the same materials in the storage and heat conduction processes to reduce the complexity of the heat exchange system, thereby achieving the goal of reducing system costs.

A thermoelectric material (also called mathermoelectric material) is a functional material that uses the movement of carriers within a solid to achieve direct conversion of thermal energy and electrical energy. Its operating principle is that solids have different properties. different temperatures. Characteristics of the excitation of electrons or holes. When there is a temperature difference between two ends of a thermoelectric material, the difference in the number of excited electrons or holes at the two ends of the material will form a potential (voltage) difference. Thermoelectric materials are mainly divided into four types: semiconductor metal alloy thermoelectric materials, skutterudite thermoelectric materials, metal silicide thermoelectric materials, and oxide thermoelectric materials.

This appears One of the reasons is: the pressure of cold water does not match the pressure of l hot water, resulting in a difference between cold and hot water pressures.

Solution:

Two methods: The first method is that the lift of the cold and hot water booster pumps must match. Specifically, the owner's lift settings should be roughly the same. In our experience, many homeowners have cold water booster pumps at home. There is no booster pump for hot water. It is recommended to install a corresponding hot water booster pump. The second method is to install a constant temperature water mixer in the main water valve or install a constant temperature water mixer in the shower. room to solve the problem of cold anddifferences in hot water pressure.

Recommendation: It is best to find a professional master to come and inspect and install.
