LuckySolar - Integrated Pressure Bearing System
Integrated pressurized solar water heater working principle: The vacuum tube absorb the solar ray and conduct the heat to heat-pipe (inside) by the aluminum slice, because the heat-pipe is connected with the copper connector which in the water tank, so there exists heat exchanging between the heat- pipe and copper connector, when the heat exchanging goes on, the water in the tank will be heated and become hot water.
- Pressurized system ensure to provide strong water flow for shower
- This type doesn’t need any controller, circulation pump, expansion pump. Feeder tank, it also can supplement cold water automatic
- We use the advanced ring-argon arc welding .ensure the high quality.
- Thickness of inner tank: 1.2mm-2.0mm food grade SUS304 stainless steel
- Even there is a tube broken; the system can work in a good condition
- This type is cheaper and easy install than the separated pressurized solar water heater. i think it will popular and have a good market .
A further, very important factor in selecting your evacuated tube collector is the quality of the internal heat-transfer-fin as this is often overlooked and generally very thin or poorly formed to cut costs, or is even 2 or 4 separate pieces. All this will ultimately reduce the efficiency of your collector, and as such your electricity saving.
