Seperate High Pressure Solar Water Heating System
DESCRIPTION
The system separates the collector and the heat storage tank. The tank can be arbitrarily placed, hot water storage tank replacement heating device and electric auxiliary heating devices. Collectors absorb solar energy light into heat water or heating medium circulates between the collector and the heat exchanger means to promote heat transfer between the collector and the natural flow of media devices, media devices through the heat exchanger and the heat storage tank the water heat exchange,
