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

Working principl

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 Tmax, then start the auxiliary heating device

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

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

5) In case the temperature of the circulation pump does not reach the set value, the circulation pump shall be shut automatically
