solar heating system

Split pressurized solar collector Working principle: 

Split pressurized solar water heater has solar collectors on roof and water tanks inside the house. When the difference of collector temperature and tank temperature gets to the set value, the circulation system will start work. It will transmit the solar energy from solar collector to the tank.

1) The operation of the solar collector is very simple.
2) Solar absorption: solar radiation is absorbed by the solar tubes and converted into heat.
3) Solar heat transfer: heat pipes conduct the heat from within the solar tube up to the header pipe
4) Solar energy storage: water is circulated through the header, via intermittent pump cycling. Each time the water circulates through the header, the temperatures is raised by 5-10 C. Throughout the day, the water in the tank is gradually heated
