  • Wall furnace with side vented draft hood
    Patent number: 5368012
    Abstract: A wall furnace is disclosed in which a secondary heat exchanger is provided to maximize the heat transfer efficiency of the furnace. The secondary heat exchanger faces the room to be heated but is aligned directly behind the primary heat exchanger. The length of the secondary heat exchanger is shortened as compared to the combined length of the combustion chamber and primary heat exchanger so as to reduce inefficiencies due to reheating of the combustion gases and to promote air flow and heat transfer around the secondary heat exchanger. Thus, this configuration provides for two essentially separate circulation circuits for heat transfer and maximum furnace efficiency. Separate heated air deflectors are also provided for each of these circuits. A side venting draft hood is also disclosed.
