the extremely effective evacuated tube collectors provide you with more annual output than that of a standard flat plate unit of the same net aperture area and work very well in windy, cold conditions.

In essence, the Tiafe thermal collector consists of a glass tube made of extremely strong transparent borosilicate glass with a copper heat pipe inside. A vacuum inside the glass tube provides the high level of insulation that is the reason it is so efficient.

Solar rays pass through the glass tube to heat a copper heat pipe. Inside the heat pipe a nontoxic liquid carries the heat to the top of the collector unit where it is transferred through a manifold to your water heating system.

The round tube configuration maximises the solar collection area, whilst minimising reflection, from sunup to sundown.
