I just hate wasting all of the heat created while running the engine or generator. The Travco has an electric water heater and I know that it is possible to get one that heats with propane, electric and engine heat. So I think it would be awesome to have a manifold that would allow me to use either engine (coach) coolant or generator coolant to heat the water in the water heater. In the Winter I could also use the return heat from that line to heat the rear compartment area. Then, another thought came to mind. What about using some coils and insulated hose with a pump to convey heat from the campfire to heat water and heat the compartment?
So it looks like Suburban makes a water heater that is direct spark LP, with electric and "motor aid" SW6DEM
Thursday I will be picking-up a used version of the above for FREE... well I may need to provide some free slave labor in return, LOL! Assuming it works and will fit the Travco properly, I will be in better shape! No more running the generator just to heat the water, I can use LP instead. And every time I run the genny, it will heat the water with the motor assist! Plus, when I am at a site with electric, I don't have to use the LP or Genny to heat the water, YEAH!
I picked-up the water heater and it is LP and motor assist, no electric. However, it is possible to add an element to control separately. At least it does not have a pilot light, it uses direct ignition.
