While the water in the pipes may freeze as long as the tank remains in motion the chances of it freezing are reduced.
HOt water looses heat faster than cold water , because it has heat to loose
this is one of those 'phrases' that is always miss-stated and miss-interperted
it will NOT freeze UP, before an equal size tank of cold water does
it has too loose all that heat before it can began to get cold
he might be talking about an enclosed sealed water heating tube system
not feeding hot water into the fresh water tank ?
convection would keep it circulating, WH would not run constantly
or maybe use a small aquarium/fountain pump
certainly it can be done
my first class A, had a WH with pilot flame, i left it on pilot all the time, except for LP refills, it never blew out
The Mpemba effect is a real phenomenon that is not totally understood, but under certain circumstances the hotter water will freeze first.
Google Mpemba I did not create the pages of info and experiments that will come up.
I agree the circulating warmer can be done. But the more I think about it would it be just as easy to travel with empty tanks. And just fill close to your destination. You would have to travel through extreme cold on a regular basis to make such a system worthwhile.
I'm sure there are those who can benefit from a recirculating fresh tank warmer, but the average RV'er is not out in those conditions.
Nevertheless If the fridge can run while traveling down the road . I imagine a hot water heater can as well which was really the question.
