Solar heat pipe collector
Split pressurized solar heat pipe collector
Working Principle
Active system
Active solar water heater systems use electric pumps, valve, and controllers to circulate weater through the collectors, this system is easier to be installed than passive systems because its storge tank do not need to be installed above or close to the collectors. The cold water supply is connected to the soalr storge tank. Water to be heated circulates between the storage tank and the solar collectors. The bumps or electric element turns on only if the temperature can not be maintained by the solar heater.

Parts: Split heat-pipe type solar system is composed of three components --- pressured heat storage water tank, vacuum heat collector (a cooper-tube style heat pipe inside) and support.
