Working principle:
1） When the temperature of heat collector reaches the set value, the controller will make 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 teperature 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 maximum temperature, then start the auxiliary heating device.

Structure:
The seperated pressurized solar water heater is composed by heat controller, storage tank, controller, working station and installation parts.
