Common reasons and repairs for a solar water heater not supplying water:
1. Water supply pipe problem
If it turns out that the solar water heater is not supplying water. The first thing to check is the water supply pipe. If the valve is not open or there are foreign objects in the pipe, the water heater will not be able to supply water. In this case, it is impossible to detect the problem with the naked eye. You can turn on the bathroom faucet and test it. If the water is flowing normally, you can basically determine that it is a water supply problem. pipe. In this case, you can use a thin wire to clean the water supply pipe. After removing foreign bodies, normal water supply will be restored.
2. Water inlet pipe problem
Many friends tend to confuse the water supply pipe and the inlet pipeof water. Water supply pipe refers to the pipe that supplies solar water. water heater, while water inlet pipe refers to the nearby water pipe. This part of the water heater housing has thin pipes. Because the pipes are thin and there will be scale deposits, as the life of the water heater increases, water will enter. will easily become smaller or blocked. In this case, you can remove the valve and clean the water inlet and water inlet pipe to return to normal.
3. Damage to the circulation pump
The circulation system of some solar water heaters relies on the circulation pump to provide pressure. If the power supply line is damaged, the circulation pump will be damaged. , coupled with scale deposited in water pipes. If there are too many, there will be a situation where the water supply line will not supply water. When you meetThis situation, there is no good solution, and it cannot be fixed by individuals. You must disassemble the water heater to check. Generally, the warranty on water heaters is around 8 years. You can call the after-sales service number directly. and let the other party's professional maintenance personnel help solve the problem.
4. Blockage of the overflow pipe
In addition to the above situations, there is another situation caused by the blockage of the “overflow pipe”. This thing has several names. vent pipe or exhaust pipe, it is usually located above the water heater. When water enters the heating cabin or insulation cabin, the gas must be discharged because it occupies the space in the cabin. If the overflow pipe is blocked, the internal gas cannot be discharged, which may cause water to enter slowly or slowly. no way. In this case you can replace directly the overflow pipe.
5. Insufficient water pressure
If the water heater was just purchased not long ago, the above problems generally will not occur. However, solar water heaters have different water supply methods depending on them. different brands, structures and models. Some water heaters rely on water pressure for water circulation and do not have external pressurization equipment (circulation pump). Take the example of tap water commonly used at home. If the tap water pressure is not sufficient, water will definitely not be able to enter. In this case, either connect an external pressure pump or wait until the water pressure is sufficient and try again, and the water will flow normally.
