Setting up a propane system (stove on demand hot water)

[Cheechako]

To be clear, that water heater locker needs to be sealed from the rest of the boat, like the propane tank locker. Will you be venting it with a pipe and out let? or trying to use the deflector? I'm not sure there's enough height in most boat lockers to just use the heat deflector...

Is your Crowther 150 a catamaran, mrbyas?

Our mono, has two separate lines, one for the stove and one for the on-demand water heater. The water heater itself is vented to the out of doors through a deck vent, and is in the shower compartment, where a fan that blows air through the shower comes on with the water pump. In addition, there is a port. There have been no problems with this installation, either for the previous owners, nor ourselves (since 2003, for us.)

I would like to comment here that if the water run is long, the on-demand is a bit of a joke, as it has to pump the cold water to SOMEwhere, preferably not one's skin. What would be good would be a thermostatic switch that would turn the water back to the tank until it was a comfortable temperature, then let it flow through.

Good point Ann. Unlike many here, I like the on demand, but when I have had them, have always used them near the source and used them like a propane stove; Switch propane off after showering and on before. My 4119 camping unit was far superior to my early unit and provided fairly steady temperature heated water.
