My husband and I are thinking about having a heated driveway

but before we start calling contractors, we're trying to gather as
much
information as possible about the different types of systems, the
cost
(of installing and operating), and general information about heated
driveways. We live in Pittsburgh, Pa. (where it's hilly and snowy)
and
have a short, steep, concrete driveway that my husband is tired of
shoveling every winter. (We're especially interested in systems that

can be installed in an existing driveway). I was hoping someone here
might be able to provide some information about heated driveways or
point me to other sites, and share their experiences with heated
driveways (good or bad).

Geez, I think I've replied to a number of threads. I'm looking into it
as well. Take a look at

www.warmzone.com

They have an option for retrofitting an existing driveway by cutting
notches in it and laying down the heating wire. If you have a very
long driveway, they have a couple of pics which show just the tire
track area heated.

It costs approx 1kwh/100 sq feet of coverage, but it only turns on when
it's WET and COLD outside... i.e. snowing.
