Heat tracing on water lines

[Jls]

Has anyone contemplated placing heat tracing on water lines?   I see two reasons...1. eliminate worry while on the road during springtime cold snap after dewinterizing and 2.  possibly eliminating the need to winterize at all.

12 volt heat trace is about 3 watts per foot, and I'm not sure how you would calculate the length needed to protect the hot and cold loops.  We picked up our trailer during a terrible ice storm with icicles hanging off the trailer while going down the road.  There was real concern of freezing pipes.  We said: Damn the warnings, we're running the gas furnace while going down the road!

We’ve run the furnace while driving too.

We’ve never towed in freezing temps and don’t plan to! 🤣

We use the furnace when it freezes overnight when home and haven’t winterized since we’re often leaving again soon.
