A system including a solar heat collector and a heat receiving structure has a supply conduit extending through an airspace within the solar heat collector, to the heat receiving structure, and into the heat receiving structure. A temperature sensor within the airspace of the solar heat collector measures a temperature within the airspace of the solar heat collector and turns an air pump on to move air through the supply conduit it this temperature is too high. This air may be exhausted through a bypass valve instead of being pumped into the heat receiving structure. The heat receiving structure may include a pool with water heated by bubbles of hot air from the supply conduit.
