Solar Hot Water Install

Today found eight of us crawling around, inside, under and atop a home in Blacksburg to install a Solar Hot Water system. We are installing an evacuated tube system that has an on demand hot water backup that senses the temperature of incoming water before coming on, so it does not power up unless there is a real need for hot water. The typical on demand system has only a flow switch which automatically comes on when the water is flowing, which in a solar system is a problem because the solar tank can have water that already is 120 plus degrees F. So finding one with not only a flow switch, but an incoming temperature sensor is critical for a solar system. For more info on the Stiebel Eltron tank we are using click the link. I will have photos of the install posted soon.
