Re: Permanent Solution to Frozen Ground

Bill, Paul,

I like this idea, except why use perforated tubing? If you blow the air to the far end of the tubing is will come back out the near end of the pipe. A small residential forced air furnace should do the job; if the fan was set to blow continuously ambient air would do the job a lot of the time; the thermostat would turn on real heat only when needed.

Insert tubes and force ambient air in sufficient quantity to offset heat
sink. Possible headers at both ends but that may be more effort than
preferred. Alternately, perforated tube inside larger tube to create closed system at each tube. It could be vented to an air conditioned zone.

This would also work with Bill's brine (more technology) and, as noted,
would lead to higher cooling load in freezer (and lower cooling load in

I have a client with a spiral freezer that has ground heave below the
freezer.  I'm looking for a way to thaw the ground and keep it thawed.
