Pool water is pumped through the filter and then through the solar collector(s), where it is heated before it is returned to the pool. 

 You can significantly reduce swimming pool heating costs by installing a solar pool heater. They're cost competitive with both gas and heat pump pool heaters, and they have very low annual ......

The separate pressurized solar water heater composes of solar collector, storage tank, controller, working station and installation parts.

Working principle:

1) The heat-conducting liquid transfers heat to water by heat exchanger in the water tank

2) In case the temperature of the water tank does not reach T max, then start the auxiliary heating device

3) When the temperature of the heat collector reaches the set value, the controller shall start the circulation pump automatically

4) The circulation pump makes heat-conducting liquid circulate automatically

5) In case the t......
