  • Westech Solar Integrative Controller

    The operation of a Westech solar collector is as follows: Solar radiation is absorbed by the evacuated tubes and converted into heat. Heat pipes conduct the heat from within the solar tube up to the header. Water is circulated through the header via intermittent pump cycling. Each time it circulates...

  • Westech Solar Collector Systems

    The Westech Evacuated Tube Solar Collector 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 hot water heating, space heating and even space cooling via use...

  • Westech Evacuated Tube Solar Collector

    If you’ve ever used a glass lined thermos, you know that a vacuum is an excellent insulator. Evacuated tubes absorb solar energy and convert it into heat for use in water heating. The insulation properties are such that while the inside of the tube may be up to 300° F, the outer surface is cold to the...
