Old oil furnace efficiency.

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. Money aside today s furnaces pollute less and boost comfort by. Old low efficiency furnaces with natural draft flue gas continuous pilot light thick walled heat exchangers may provide efficiencies ranging from 56 to 70. We don t have any records of annual oil usage or any way to find that out.

We purchased a house with what appeared to be a relatively well maintained oil furnace about 30 years old installed in 1984. Consequently a loss in efficiency means your heating bills may go up.

All new furnaces are. Remeber the extra money you re spending every month on a less efficient furnace could be going toward the cost of your new more efficient system. Upgrading your furnace or boiler from 56 to 90 efficiency in an average cold climate house will save 1 5 tons of carbon dioxide emissions each year if you heat with gas or 2 5 tons if you heat with oil. Replacing the old furnace in your central heating system with a new more efficient model can offset volatile energy prices.
