I thought you told us everything on the boat was perfect?
Even on my 'ugly racer", the water is heated by the engine or shore power.
And it has worked reliably since the day I bought the boat.

The boat's in clean shape, as I've always said. But I never got around to
commisioning the fresh water system. The hot water heater/Heat Exchanger hoses
and just everything else was disconnected. Took a while to sort it all out.
