ABSTRACT:
The method disclosed includes positioning a furnace disposed within a shelter outside near the building, the shelter has an inlet for receiving ambient air and an outlet for passing air heated by the furnace out of the shelter. An air duct is mounted between the shelter and an opening into the building. A solid fuel is burned within the furnace to heat the air within the shelter and the heated air is transported through the duct into the building to provide supplemental heat in the event the supply of fluid fuel is interrupted.
The apparatus disclosed includes a shelter having walls with an inlet for receiving ambient air and an outlet for passing heated air out of the shelter. A furnace is disposed within the shelter for heating the air and includes a grate for supporting solid fuel to be burned and an exhaust stack extending through the walls of the shelter for carrying exhaust gases from the furnace without mixing with the air within the shelter. A duct is adapted to the mounting between the shelter and an opening into the building and the heated air passes through the outlet of the shelter and carried through the duct into the building to supply heat to the building in the event the fluid fuel supply is interrupted.
