This Radiance direct-vent propane heater will provide clean-burning, energy-efficient
heat downstairs. Vents in the stairs near the heater will allow the heat to also
rise into the upstairs area of the home. Heat will be stored in the thermal mass
of both the above and below grade concrete walls so only a minimum of heat will
be required to keep the home comfortable during the winter. (March 1, 2006)
The base of the shower area is made from concrete which will be stained and sealed.
Before pouring the concrete, a waterproof liner and rebar are installed. Crack-resistant
