Sid.

The outside of the basement is already insulated, with dirt.
I insulated my poured basement walls with studs, insulation and sheetrock.
The average year round temps down here, without any heat supply, is
between 62-75º F.
I do have the oil boiler and propane water heater down here, which
supplies a little heat in the winter, and the house AC helps cool it in
the summer, since cool air flows downward.

Dirt is not insulation, my freeze depth is 3.5ft, dirt transfers cold.
