How to clean the water tank of heat pump water heater and how often?

The water tank of heat pump water heater is generally cleaned once every 3 months, depending on the local water quality.

Cleaning steps:

1. Determine the amount of cooling water stored in the system, and calculate the amount of chemicals required for scale removal.

2. Prepare materials according to the composition standard of the scale remover. When using solid scale remover, it must be stirred in a barrel to completely dissolve it, and then added into the system; When using liquid scale remover, defoamer should be added to prevent excessive foam.

3. Drain the water in the water collecting tray and thoroughly remove silt and dirt.

4. Close the drain valve, inject clean water, turn on the water pump, and let the water circulate.

5. Add scale remover in the process of water circulation. The place where the scale remover is applied can be the water collecting tray of the cooling tower.

After cleaning, drain the waste liquid into the sewer and rinse the system with clean water.

After adding the scale remover, the system runs circularly. Because most of the scale is carbonate, it can dissolve the scale and make the system reach the required cleanliness after running for so long. Dongguan keanxin energy-saving equipment co., ltd
