How it works:
1) The operation of the SPA solar collector is very simple
2) Solar absorption: Solar radiation is absorbed by the solar tubes and converted into heat
3) Solar heat transfer: Heat pipes conduct the heat from within the solar tube up to the header pipe
4) Solar energy storage: Water is circulated through the header, via Intermittent pump cycling. Each time the water circulates through the Header, the temperatures is raised by ***0oC / ***8oF. Throughout the day, the water in the storage Tank is gradually heated, We adopt the advanced technology to produce solar water and its related spare parts.

>Vacuum tubes are the heart of solar water heater, our vacuum tube uses the borosilicate Glass which has magnetron sputtering aluminum nitride absorbing coat. We have 2 models: *7mm x 1, **0mm, *8mm x 1, **0mm, >Insulating layer was polyurethane foamed,

>Bracket made of premium cold roll with Plastic spray or stainless steel.

> Fastening pieces was made of stainless steel Screw.
