 | Here
is a simple project that you can build out of easily available parts. Take
two drums and paint them black. Build a wooden box and insulate it with sheet
styrofoam about one inch thick. You can get this foam at most large "Home Do-It
Centers" in 4ft. x 8ft. sheets. Paint the inside of the box black. Make a lid
by building a wooden frame and insert a sheet of glass, double pane would be
even better. Place the heater at an elevated site or on tower (for water pressure)
and orient the glass towards the south. |
