I'm sure the first thing you noticed is the huge difference in annual heating costs between
a tuned up furnace running at 80% efficiency and a neglected or worn out furnace
operating at only 65%.
If your heating plant is tuned up on a regular basis call the folks who service it to find out
how efficient it's running. If your furnace or boiler hasn't been given the once-over in a
while, now would be the perfect time to find out how efficiently your heating dollars are
being spent.
Generally speaking, if your furnace or boiler is more than 15 years old you should consider
replacing it with one of the newer high efficency units. If you have yet to take advantage
of the Federal incentives for energy efficient appliances you are still elegible for up to $500
in tax credits.
*Fuel costs are averaged from suppliers in Maine, Massachusetts, Connecticut, Vermont
and New York and based on approximately 90 million Btu's of heat annually.
