This water treatment/circulation for the fresh water tank got me thinking.....:R
How would using the fresh water supply work if a guy also used that water for hydronic heating? My initial though was to plumb the hot water tank outlet through a small heat exchanger and use the fresh tank as the reservoir. I could probably control the output of the water heater with a thermostatic valve.
Or, would it be better to establish new plumbing for the hydronic system?
If an RV'er wasn't worried about the supply lines freezing (mine are all inside), using heated water for some heating and to circulate back to the tank could be really nice for Winter camping. In my special case (steel fresh water tank under dinette seat) it would keep the dinette warmer, too.
