Knowledge on the use of automatic water supply solar water heaters
Water supply does not stop
The reason is that the chain of the single-tube water inlet and outlet valve is too long
Poor water quality can easily generate scale or impurities accumulate on the valve core If the valve body is not closed tightly, the valve body itself will be damaged.
Troubleshooting method: Cut off the excess chain links according to the standard length and install a check valve with a filter to replace the valve body. Note that if users encounter the above situation, please do not disassemble it yourself and contact the local service provider for troubleshooting.
The solar energy makes a whirring sound when filling the water
Cause When the water tank is almost full, if the water pressure is too high and the float floats up and down, the valve will suddenly close and open. When the float valve is suddenly closed, a space vacuum is formed because the valve core is suddenly lifted up and the incoming water cannot be replenished. Vacuum is the best medium for sound transmission, so a large vibration will occur.
Troubleshooting method: Install a flow limiting valve. Note that if users encounter the above situation, please do not disassemble it yourself and contact the local service provider for troubleshooting.
Is the water temperature not high?
Generally there are the following reasons
) There are trees, tall buildings and other obstructions above the water heater.
) The water supply valve is not closed tightly. Tap water (cold water) pushes out the hot water in the water tank.
) Too much sediment in the water (such as well water) is deposited in the vacuum tube, affecting heat collection and circulation.
) The local air pollution is serious and there is dust on the surface of the vacuum tube. If the above problems exist, the first step is to remove the obstruction or reselect the installation location. The second is to replace the water supply valve. The third is to disassemble the water heater and rinse it with detergent and clean water. This situation is an exception. Fourth, just scrub the vacuum tube.
The water tank is not full of water?
When encountering this situation, first check whether the tap water pressure is sufficient. If the pressure is not enough, a micro water pump can be added. Second, check whether the upper and lower water pipes are leaking. If there is water leakage, replace the pipeline valve or joint. The third situation may be that the water tank itself is leaking. In this case, the only option is to replace the water tank or re-weld the water tank.
Water leak?
First, the sealing ring is damaged or the water tank is incorrectly installed. The solution is to replace the sealing ring or reinstall it to align the water tank with the vacuum pipe. Second, the water tank liner is open and welded. You can ask a professional to repair the welding or replace it with a new one. The third is that some indoor or outdoor pipe fittings are broken.
Is the water temperature hot and cold?
This is due to the high pressure and instability of the water tank. At this time, the user can add an auxiliary water tank on the roof to store cold water and stabilize the pressure to mix cold water, or use an automatic thermostat valve.
In winter, there is not enough hot water but there is a lot of cold water?
) is caused by the freezing of water and sewer pipes in severe winter.
) The weather is too cold.
) No insulation.
