Old oil furnace efficiency.

Old low efficiency furnaces with natural draft flue gas continuous pilot light thick walled heat exchangers may provide efficiencies ranging from 56 to 70. If your furnace or boiler is old worn out inefficient or significantly oversized the simplest solution is to replace it with a modern. In this case the best way to reduce your energy bills is with a high efficiency furnace. From what i can tell it was originally 80 afue.

We purchased a house with what appeared to be a relatively well maintained oil furnace about 30 years old installed in 1984. As furnaces age they often lose their efficiently. All new furnaces are. Although gas furnaces are more efficient than oil furnaces that efficiency comes at a price gas units are typically priced 10 to 25 higher than the same size oil furnace.

New high efficiency furnaces with condensing heat exchangers fan assisted exhaust and electronic pilot light may provide efficiencies ranging from 93 99. Replacing the old furnace in your central heating system with a new more efficient model can offset volatile energy prices. Consequently a loss in efficiency means your heating bills may go up. We don t have any records of annual oil usage or any way to find that out.
