I was watching a building program yesterday, and the builder said it was
12c constantly 2 metres underground. They was building a house in
Maidstone, Kent.

I know builders are known for telling porkies, but is it true that just 2
metres underground the temperature is constant?

Hmmm I wonder how that squares with heatpumps? May that's the temp they
bring the mains up to.
