The reasons why the solar water return pipe does not return water are generally the following five reasons:
1. The tap water pressure is too high:
The tap water pressure is too high:
The tap water pressure is too high , it will cause heat. Water cannot flow. It is necessary to reduce the flow of tap water or add a booster pump. Once the tap water pressure is balanced, hot water can flow.
2. Vacuum Tube Problem:
Many families install vacuum tube solar water heaters. Vacuum tubes are important components for absorbing solar heat sources. If the vacuum tube is not cleaned for a long time, it will affect the heat absorption capacity, and only cold water will come out, but no hot water will come out. Evacuated tube solar water heaters absorbheat and heat up quickly on sunny summer days. If no one at home uses water for a long time, the water tank will be in a state of high temperature and pressure for a long time. which will cause the water tank to age and become unable to supply water. Additionally, damage to the vacuum tube resulting in insufficient heating will also prevent the solar water heater from producing hot water. Vacuum tubes should be cleaned in time and replaced if damaged. If no one is at home for a long time, a cover should be placed over the vacuum tube to block sunlight.
3. Cross water flow problem:
There are many pipes when installing a solar water heater. If cold water is flowing, there may be a cross flow of water. This phenomenon requires the installation of an independent valve and the closing of the valve to avoidhot and cold flows.
4. Impact of fully automatic auxiliary water tank:
If the float valve of the fully automatic auxiliary water tank is not closed tightly or fails, it will cause more cold water and the water temperature will decrease and what will flow out is not hot water. Fixing this problem requires replacing the float valve and associated parts.
5. Leaks in sewer pipes, valves or joints:
Pipes and their components are usually found outdoors and are easily damaged by wind and sun. If problems arise, they must be repaired and repaired. replaced in time.
Solar energy refers to the energy of thermal radiation from the sun (see the three modes of propagation of thermal energy: radiation). Its main manifestation is often called solar rays. Nowadays,it is generally used to generate electricity or provide energy for water heaters.
Since the birth of life on earth, it has mainly relied on the energy of thermal radiation provided by the sun. Since ancient times, humans have also known how to use sunlight to dry objects and use it as a method. to prepare food, such as making salt and drying salted fish. With the decline of fossil fuels, solar energy has become a significant part of human energy consumption and continues to grow. There are two ways to use solar energy: photothermal conversion and photoelectric conversion. Solar power generation is an emerging renewable energy source. Solar energy in a broad sense also includes wind energy, chemical energy, hydropower, etc. on earth.
