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.
