INTERMA Solar Collector or Solar Water Heater is a device that absorbs thermal energy from the sun and converts it into usable heat. The heat is normally absorbed by water, or a freeze resistant water mix, which can then be used to supplement hotwater heating, space heating and even space cooling via use of an absorption chiller or dessicant cooler technology.

The operation of the solar collector is very simple.
1. Solar Absorption: Solar radiation is absorbed by the evacuated tubes and converted into heat.
2. Solar Heat Transfer: Heat pipes conduct the heat from within the solar tube up to the header.
3. Solar Energy Storage: Water is ciruclated through the header, via intermittent pump cycling. Each time the water circulates through the header the temperatures is raised by 5-10oC / 9-18oF. Throughout the day, the water in the storage tank is gradually heated.
