The Tubes

Step 1

The sunlight strikes the dark absorber coating inside the evacuated tube.

Step 2

The heat pipe transfers the heat up to the copper header pipe location in the insulated manifold box.

Step 3

A circulator moves water from the storage tank to the copper pipe warming the water. The solar heated water is then pushed down into the storage tank for use. Anti-frost is built in to the Thermann system to ensure solar hot water can be provided even in cold regions.
