That's the one benefit of this house being so old and sieve-like (very poorly insulated). The attic is currently 54º. But we've got very little plumbing in the attic since this is a pier and beam. Most of the plumbing is in the crawlspace which is normally fairly open. But I did work to mostly enclose the crawlspace. And because of the lack of insulation, lots of heat migrates out of the house through the floor, so the crawlspace is essentially heated by the house.

By next summer (and next winter) the bottom of the house and the plumbing there, will be insulated.
