Routine maintenance of solar water heaters

1. When installing a solar water heater, there may be dust or oil smell in the water pipe, and you can open the faucet to remove debris when you use it for the first time.

2. The water stored in the solar water heater should be discharged regularly according to the local water quality conditions, and the drainage time can be selected in the morning when the collector temperature is lower.

3. The surface of the solar water heater should be wiped regularly according to the amount of dust falling in the region, and it can be cleaned by itself when it rains, and the surface of the water heater can be kept clean to obtain a higher heat collection efficiency.

4. When you do not use hot water for many days on sunny days, the hot water temperature is very high, please turn on cold water first and then hot water when using the solar water heater to avoid scalding.

5. There is generally a filter screen device at the outlet end of the faucet, and the scale and debris in the water pipe will gather in this net, which should be removed and cleaned regularly to increase the smooth flow of water.

6. In winter, it is very common for the pipeline to be frozen, such as finding that the pipeline has been frozen but the pipeline has not yet cracked, and it can generally be automatically dredged after the temperature rises. You can also use a hair dryer to blow it, or wrap the water pipe with a towel, and then pour it slowly with warm water, do not use fire to bake, knock on the pipe or use boiling water to scald, that will make the pipe burst. Repeated freeze plugging can easily cause the pipeline to freeze and crack, so it is necessary to strengthen the pipeline insulation measures.

7. Solar water heaters need to be cleaned, inspected and disinfected every two to three years on average, and users can also do some disinfection work by themselves, such as buying some chlorine-containing disinfectants and pouring them into the water inlet, allowing them to soak for a period of time, and then releasing them, which can have a certain disinfection and sterilization effect.

8. The inside of the vacuum tube needs to be cleaned in two to three years on average for solar water heaters to prevent scale formation inside the vacuum tube from affecting the heat absorption effect.

9. If the solar water heater is equipped with a special meter, pay attention to lightning protection and electricity, do not take a bath and unplug the electric heating plug when thundering.
