winter heat to protect foundations

Foundations do not need to be heated, in fact if it was warm on the inside and cold on the outside it could do more harm then good, not likly but remotely could.
Foundations fail most often because there was a poor footing they were built on, nothing to do with not being heated.

What you need to be concerned about is frost getting under the footings and post pads and doing damage. If the floors in (likely not in at this point yet) they can be damaged from frost heave as well.

You can either use temporary heat, or insulate very well to trap the earth's heat in. Depends alot on where you are, how extreme your winter weather is, and how long before you can get the house insulated.

As for how much heat? Just enough to keep the basement from freezing, but I can tell you from experience, a house at this point of the process uses ALOT of fuel to keep it from freezing on the extremely cold days......

My basement is anywhere from 62 in the Winter, and around 70 in the Summer. All I have down there are two vents to help keep the space dry and stop the stale air smell.

Before we got central air, the basement would get to 76, while the upstairs was around 72, with three window units coolong the house, one was always running 24/7, others when we got home after work.
