Hi Profdant,
Change of state from liquid water to ice. It takes a LOT of energy to do so.
For example to freeze one gallon of water takes about 1368 btu's of heat removal.
Since even a small water tank would have 20 gallons it takes a long long time to freeze--and if it DOES it takes a long long time to thaw. Temperature change would be 32.1 to 32. The total amount of energy would be about 27000 btu's--or similar to running the furnace for one hour!
Probably if temperatures go up to 40 during the day, most Rv's can tolerate 28 F during the night. Below that, and water lines (which don't have much water in them) start being a problem.
