Brief Introduction of Evacuated Glass Solar Tubes.

Evacuated Glass Solar Tubes (EGST) are the key components of Solar Water Heating Systems.

The EGST have the best possible insulation, a vacuum jacket, which allows sunlight to pass through freely but stops the thermal heat transferring back out.

They feature high efficiency, low heat loss and are guaranteed for ten years.

The use of evacuated glass solar tube technology appears to be one of the significant developments in the solar industry, world wide.
