Features:
1) Cover a window on heat pipe solar collector, has better appearance.
2) Reliable and efficient twin-glass solar tubes
3) Copper heat pipes for rapid heat transfer
4) Easy plug-in installation
5) Free maintenance
6) Work pressure: 8bars
7) Stable solar conversion during the day
8) The perfect solar collector for domestic solar water heater systems
9) Ideal for commercial solar water heating applications
How it works:
1) Connect with pressure water tank and workstation. 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℃. Throughout the day, the water in the tank is gradually heated.
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
