Solar Collector System, Heat Pipe Vacuum Tube, Solar Water Heater, Split Solar Thermal Collector
The separate pressurized solar water heater system is made up of solar collector, pressurized water tank, working station, expansion tank, stainless steel frame and whole kit of stainless steel fasteners.
1. The water tank includes two heat exchange coil inside and a 1500 electrical heater as a backup heater.
2. The working station includes circulation pump, intelligent controller with sensors, setting online (flux controller), pressure meter, pressure release valve, one-way valve, ball valve, copper pipes, insulation shell.

Working principle
1) When the temperature of the heat collector reaches the set value, the controller will make shall the circulation pump work automatically.
2) The circulation pump makes heat-conducting liquid circulate automatically.
3) The heat-conducting liquid transfers heat to water by the heat exchanger in the tank.
4) In case the temperature of the circulation pump does not reach the set value, the circulation pump will be shut automatically.
5) In case the temperature of the tank does not reach Tm ax, then start the auxiliary heating device.
