Bathroom renovation and water heater.

[artvonne]

  Im tentatively planning a short electric water heater in the cargo bay, modified with three loops. One loop to/from the engine, one to/from the generator, and, after by-passing the heater lines from the engine, a loop to/from the OTR heating system.

  Perhaps a fourth loop, and plumb in a small propane RV water heater for backup/auxilliary heat.

I also thought about plumbing from the generator but, if it's an electric heater, and the generator is running, I'm not sure it's necessary, or, at least worth all the effort. But worth it or not, you would get heat from it! I'm not sure what you are talking about with the third loop. To me, 1 and 3 are the same but I guess you may be configured different.

  Im intending to use the OTR heat as the primary heating system, so it has to provide heat without the engine running. I suppose I could keep it within one loop and use check valves, but thinking thats just something else to fail.

Got it. Thanx Art.
