Evacuated Solar Heat Tubes

The Solar Heat Tube system is a unique system, which by comparison with many other solar boiler systems has a very high efficiency, both in summer and winter.  It uses high quality thick barium oxide glass vacuum tubes in which an absorber collects the sun’s infrared radiation and transfers this to the water that is running through a tube in the center of the absorber.

Distinguishing points of this system are the high efficiency, high quality and its great longevity. It is simple, and easy to install and maintain. The system is capable of being mounted from the vertical to the horizontal orientation.
