Technical Parameters
Collector: Aluminum alloy casing
Vacuum tube: high efficient super heat pipe
Insulation tank: SUS304 pressurized storage tank
Circulation system: double pipes self fillng working station
Working pressure: 7bar
Controller: temperature differential and timing circulation
Assistant function: electric heater or gas boiler
Working temperature: -35-50ºC
Working Principle
1. The solar collector absorbs solar energy and transmits it to the solar water heater tank through circulation
2. When the temperature of the collector reaches the set value, the controller starts the circulation pump automatically
3. The circulation pump makes heat-conducting liquid circulate automatically
4. The heat-conducting liquid transfers heat to water by lower heat exchanger in the water tank.
5. When the temperature difference between solar collector and heat pipe solar water heaters tank doesn't reach the set value, the circulation pump will be shut automatically
6. In case the temperature of the water tank does not reach max, Electric heating element will start to work automatically
