Hello:

Realize that this is a question that is probably impossible to answer with
any real accuracy, but was wondering if anyone would care to offer
any estimate, or guestimate, on it:

For a 25 year old typical three bedroom split level (in the Northeast) using
the original forced gas hot air system for heat, what % "might" be saved in
going
to a brand new ("top-of-the-line") furnace in ones heating bill ?

Thanks,
Bob

How much are you paying now?

BTU of your current system?

The answer will depend alot on whether or not it is turned on after it
is installed. Also, I have found the the best way to really save on
energy costs is to buck the system, and use your cooling in the winter
and heating in the summer.

So far this year, I have only had to turn on my cooling system 4 times,
when the temp got above 40.

To many variables to answer

try this site and see if it helps you decide
http://198.147.238.24/ac_calc/default.asp

Is it one of those 50%-60 % efficient monsters with the round burner
chamber. Is it oversized heating you a bit to fast and uneven, Has it
been maintained and has a good blue flame or is it yellow. Does it have
an AC coil in the heatpath that could be clogged. You need to know what
you have now, is it running at 30% or 70% efficiency. You can go to
94.5% and get VS DC motor that will cut electrical usage by 50-60%

assuming its got decent insulation and all, i would expect enough to pay for
itself over its lifespan and then some.

hey, you wanted a guess...

Your old furnace is approx 60%, the best new condensing furnaces are 92% or
more
Check here for savings and make sure your insulation and windows are
efficient.

An old furnace can get as low as 50 or 60% efficient, plus having a heavier
fan to blow the air, so more electric. The new furnaces can be over 90%
efficient, and lighter fans.

Can't give you any specifics, but my boss and I put in one, the power
company bumped up his estimated ammount cause it was a cold year. He called
adn told them he had a new furnace, but they left the estimate. He had a
zero gas bill one month cause they estimated too far in advance.

The issue is if he is paying $60/month during 3 winter month,

$20 saving will not pay for new furnace....

If his bill is $400/month let's say $100/month saving well worth it.
