SOLAR INPUT EFFICIENCY

Fully automatic booster solar water pump

The solar-specific hot water booster pump adopts an advanced digital control system and can automatically adjust the operating status according to parameters such as water temperature and water flow.The built-in temperature sensor monitors the water temperature in the solar collector, when the set threshold is reached, the water pump is activated to ensure rapid circulation of hot water.Meanwhile, the flow sensor detects the water flow, when the flow rate is lower than the preset value, it will automatically stop working to avoid unnecessary waste of energy.
