When I took a heating course, years ago, they told us that the regional
transit service in Rochester NY installed a heated parking lot. It isn't
needed to keep it warm enough to pitch a tent and sleep out, but warm enough
to melt the snow. If memory serves, the instructor said that the heat bill
for the parking lot was less than the snow plowing service charged. Seems
the snow lands, evaporates, and the vapor floats away.
Just what I was remembering.
Forget the heated drieway idea. They are not worth the time effort or
I worked on a system in stalled in a sidewalk at a bank(electric) and I
worked at acolledge that also had a heated walk way.
You can sit here and cost average the the system to death and the one
thing that everyone forgets is that melting snow or ice turns into water
and water turns back into ice. Can you start to see the picture?
Snow or ice accumulates, system turns automaticly or manually , snow
and ice melt ,system turns off . walk or drive returns to freezing temp
and mlted snow or ice reforms into ice so the system turns back
on........... What usually happens is the stupid thing stays on longer
than it is off.
As far as the bank s system , I never went bac to that job. As far as
the colledge they just turned it off and went back to shovels and ice
We are expecting 12 to 15" of snow tomorrow. That equates to maybe 1" of
water over the surface. Considering the snow will be coming for 20 hours or
so, just how much water will be needed to heat the driveway enough to melt
all of that snow.?
You do bring up a good point though, with any system there needs to be some
provision for runoff. Just a hell of a lot more with a water system.
And if you happen to live someplace that doesn't get too cold.
[that's 'voila', BTW]
Here in NY that would work fine for an early October snow--- provided
you had tons of water, a slightly pitched driveway & great drainage.
As soon as there was any frost in the ground it would just create an
I challenge anyone north of, say, Virginia, to give this method a try
on a short section of sidewalk.
Let us know how much water it takes to clear a few square feet of
frozen concrete of 3' of snow.
Are you trolling or do you live somewhere that you've avoided the
pleasures of dealing with much snow? Nothing like a little water
under a snowfall to 'make it easier to shovel', right?
