When it's around 0 F the house gets cold pretty damn fast. Even if the
heat isn't off plumbing in a crawl space can freeze. You've obviously
never spent quality time laying on your back with a propane torch trying
to get the water going without burning down the ****ing shack.

We don't get 0F in Scotland. If you do, you really ought to insulate better.

What annoys me is the way that under the floor is vented to the outside! WTF? Vent it to the inside, then it stays warmer and dryer.

As long as you have that crawl space well insulated that works OK but
you will end up with a higher heat bill. Down here in Florida they
will backfill that stem wall with dirt and pour the slab over it.
Problem solved.
A "crawl space" with no floor, vented to the living space, would
cause a lot of humidity problems in many places (particularly
florida). Even "basements" with concrete floors can be damp if not
either vented or conditioned. You vent the crawlspace and insulate
the floor of the living space (between the floor joists) and you don't
have heat loss issues. Keep the water lines on the "warm" side of the
insulation..

"On Slab" works good in Florida where anything resembling a basement
is liable to become an indoor swimming pool - up here in the higher
elevations and more temperate to cold regions, full basements are the
rule rather thanthe exception - almost always conditioned and used as
extra living /utility space.

Furnace in the attic? Not up here. It's in the "basement" - generally
along with laundry and a "rec room" - often an additional bathroom,-
and sometimes even a bedroom or 2.
