Domestic hot water system including electric water heater, solar water heater, gas heater, air energy heater etc.. When these heater are used in hard water areas, the scales will gradually adhere to the inner heating tube, the solar evacuated tube、heat transfer system and water storage tank, lower the thermal conversion, increase Electricity power and energy consumption. According to the test, if the thickness of the adhered scale of the heating tube and solar vacuum wall reaches 1 mm, the energy consumption raises 10%. If the thickness of the scales reaches 2mm, the energy consumption increases to 30%. The thickness of 2mm will be reached in 2 months in hard water area.
The Influence Of Scale To The Heat Exchange
|Thickness Of Scale（mm）||Heat Exchange Degree（BTU/ft2/F）||Heat loss（%）|
The adhered scales on the water butt breed many germs and do harm to people’s health. The scales flakes will be partly rushed out and block the shower make the water not flow smoothly.
If you increase a scale inhibition filter unit which contains MSAP material on the water inlet of electric heater, this problem will be solved. According to different capacity of filter unit, 30ton~60ton water can be purified and used for electric heater for half to one year.
