The U Pipe series solar collector are always connected with existing heating supply device. The selective coating on the inner cover of the evacuated tube converts solar energy into heat energy and transfers heat to copper U Pipe by an aluminum fin. The liquid (usually a glycol-water antifreeze mixture) in the U pipe heats up, and transfer the heat energy to the water inside the storage tank through plate exchanger or internal spiral coils.
As the water temperature can be adjusted using an automatic controller, user can get hot water all day long.

Features:
1. Can operate with water pressure up to 6 bar.
2. Can be combined with existing energy source.
3. Storage do not need be installed above the collector
