Solar heating system consists of solar collector, controller,circulating pump, heat storage pool of water, and for the returnpipe, etc.
When the heat storage water tank water supply water temperature T1> fifty. C, the controller will start water pump, water into theheat collector, and the collector of hot water pressure into thewater tank, water tank top to the high temperature, lowtemperature, the lower the lower cold water again into thecollector to heat, make a cycle. When the heat storage water tankwater supply water temperature T2 45. C, can open pump 3 forheating cycle.

And other application of solar energy, solar collector of heatoutput changes with time, he affected by climate change, so, thesystem has a, booster heater.
