Hot water and hydronic heating
The water treatment/circulation for the fresh water tank from another thread got me thinking.....:R How would using the fresh water supply work if a guy also used that water for hydronic heating? M...

All good caveats but maybe some more background is needed. I have a whole-house solution for heating. It is a vented 20K BTU heater, propane fired, that is efficient. It does not have a fan or need any power to operate. This is the third RV this heater has been in and is a tested-to- (-20f) solution.
What I'm about is taking some of the heated water from the onboard water heater and circulating it to the fresh water tank. This is similar to what member Profdant139 did here. I will hard plumb everything and don't need an exterior fill solution like he did, I have fittings on the steel fresh water tank.
I would also like to pull out a bit of heat through a heat exchanger and fan or baseboard heater. I don't expect it to anyway come near to a whole house solution for heating. If I can get 70f at the exchanger, I would be happy. I'm wondering if circulating the water like this will have any adverse effects like algae, contamination, etc. I'm not too worried about the latter as I already have a steel tank and deal with a little iron discoloration now and then. Filtration takes care of that. I'd also be interested if anybody has pump recommendations. I know member SMKettner has one of those magnetic vane pumps and likes it a lot. They are expensive, though.
