Solar Hot Water
solar powered buildings requires some means of heating water (the
second largest energy consumer in the average home). Our domestic
hot water is created from three sources. First we have a 50-gallon
tank located in the attic space which is passively heated by a hot
air panel mounted in the roof. This pre-heats the water in the tank.
Summer temperatures in the chamber average 195 degrees with 150-degree
average in winter. This pre-heated water minimizes our use of the
propane instantaneous hot water heater.
The second means of heating is a water coil in the wood stove. When
it is cold enough to have a fire, water is heated and rises into
the 50-gallon tank above creating a thermo-syphoning effect. Preheated
water from the wood stove or from the solar panel then flows through
our propane instantaneous hot water heater, which may or may not
have to turn on depending on whether the water flowing into the
heater matches our preset temperature setting.
