2013 New style split pressurized solar water heater (300liter)

Split presssurized solar water heater working principle 
1. The collector absorbs solar energy and transmits it to the water 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 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 Tmax, Electric Heating Element will start to work automatically.
