Welcome to Solar Heat Exchange Manufacturing

After 30 years of experience we learned that there was a need for a simple, easy-to-install, solar hot water system. The Simple Drainback System fulfills this need. It incorporates simple plumbing methods with high quality equipment, low maintenance requirements and easy training to create the next generation of solar hot water systems.

Because our Simple Drainback System uses water for the solar fluid and is sealed from atmosphere, there is virtually no need for maintenance. Glycol systems require regular maintenance to check that the acidity level has not reached the point at which the copper pipes and collectors will start to erode.

Our system will also work in freezing climates without failure. Correctly installed collectors and plumbing will guarantee that the water drains back completely. Our SHEM32 controller is set to prevent the pump from activating when the temperature in the collector drops below 50°F. This provides an additional measure of protection against freezing. Our controller is also passcode protected to prevent accidental adjustments of the temperature settings.
