If you can keep the wind out you stand a much better chance of the pipes not freezing.

Having those lights on all the time would scare me. Can you get some milk heaters? Something that is made to do what you are asking it to do.

Something like this:

I'll check, but I doubt there will be any heaters available anywhere around here right now.

Never had an issue to -44C.

I'm not sure I've got time to do that, and my heat is a heat pump with electric emergency heat backup, so I don't have a ton of heat to spare for under the house or getting the crawl space sealed in the next 36 hours.

Yep, that's on the agenda, although I wonder about it's efficacy at temps as low as the single digits.
