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
