The method of cleaning without disassembly of the solar water heater is as follows:
1. Clean the water tank regularly: drain all the water from the water tank, then rinse the inner wall of the tank. water tank with clean water. You can use a soft brush to clean the inside of the water tank. Finally, rinse with clean water.
2. Install a filter: Installing a filter at the water inlet of the solar water heater can effectively filter impurities and dirt in the water and reduce dirt accumulation in the water tank.
3. Use a water treatment agent: Adding a water treatment agent to the water tank can effectively prevent the formation of scale and dirt and reduce the frequency of cleaning.
4. Check the pipes regularly: Check the pipes of the solar water heater regularly for blockages or leaks, then clean and repair themon time.
5. Install automatic cleaning devices: Some high-end solar water heaters can be equipped with automatic cleaning devices, which can automatically clean the inside of the water tank regularly and reduce the frequency of manual cleaning.
How to clean solar energy
Early preparation: Buy a special descaler for solar water heaters (if the use period is one to six years , just buy three or four packs if the usage period is If you are over seven years old, you can buy more than four packs in appropriate quantities); prepare a cardboard box the size of a solar water heater or a substitute for the cardboard box (prepare a funnel); the size of the funnel will be determined based on the size of the water tank drain outlet); prepare an appropriate amount of water
1. First cover the vacuum tube with a carton or cardboard substitute, and then drain the water from the solar water heater.
2. Take out the pre-prepared descaling agent and dilute it with an appropriate amount of water in a certain ratio
3 Remove the prepared funnel and use it for the. A diluted descaling agent is injected into the exhaust port of the water tank of the solar water heater, and then injected into the water tank through its exhaust port. (If you want to clean the vacuum tube only, you can inject a small amount of water into the solar water heater tank according to the third step; if you want to clean the inner wall of the water tank, fill it water from the solar water heater. tank based on the third stage.)
4. Wait twenty-four hours, drain the water injected into the solar water heater, then inject water again and drain the water. or three times, the cleaning of the solar water heater will be completed.
Note: ApAfter injecting the descaler into the solar water heater, you can remove the cardboard or its substitute covering the vacuum tube to allow the water temperature to rise appropriately. Remember to cover the vacuum tube once it has been installed. exposed to the sun for a long time, the water temperature will be too high, which will affect the cleaning of dirt. If your water heater is broken, it is still recommended to have a professional water heater repairer repair it. It is not safe to do this yourself.
The steps of solar cleaning and descaling are as follows:
①Open the solar water inlet and pour in the descaling liquid. Quantity depends on capacity. solar water heater;
②Pour in the descaling liquid and let the water heater circulate naturally for about half an hour, so that the descaling liquid can contact evenlywith all parts of the water heater;
③Open the drain port and drain the descaling liquid. Refill the water tank, then drain the water once per cycle. Remove the vacuum tube;
④ Initial cleaning and pouring scale into the vacuum tube
⑤ Clean and descale the vacuum tube separately
⑥ Remove the scale contained in the liquid vacuum tube scale;
⑦Clean the vacuum tube several times for descaling;
⑧Close-up of the scale in the vacuum tube;
⑨Installing the vacuum tube and debugging the system after descaling, add water, drain the water to rinse and cleaning is completed.
Instructions for descaling evacuated tube solar water heaters
① It is best to use the water from the water heater the day before and to clean it the day before. morning, which will not cause The vacuum tube heats up a lot;
② It is best to use chloric acid liquiddiluted water solution for descaling
③Be sure to wear gloves during the cleaning process; to prevent the vacuum tube from suddenly breaking and scratching your hands or getting burned;
④ After cleaning is completed, test the water in the system to ensure there are no problems before the cleaning job is completed.
