A most interesting project. It's a solar heat generator made using a sliding glass door and chunks of concrete. It uses no power but can produce temps over 84 degrees, even in winter with full sun. Inside it I used concrete blocks to act as batteries to store the heat overnights.it houses the pump, pressure tank, water conditioner and plumbing, all were safe over the winter (empty) and do not need to be brought inside. Cool right?
