A machine that improves the management of thermal energy for a residence or other building by serving as both a swimming pool 26 water heater and an attic space 22 ventilator. The heating of air within an attic space 22, resulting primarily from the insolation of the roof surface 24, is exploited to heat water 26. The device consists of an air-to-water heat exchanger coil 28, a fan 30, an air outlet passage 32 between the attic 22 and the outside air with the necessary mounting 90 and weather excluding structure 86. When water heating is not required, the device retains its attic ventilation function in order to reduce the cooling load on the air refrigeration system for the building. The device may be used as either an alternative to a fuel burning or electric powered water heater or as a means to minimize the use and expense of such heaters. |
