Is not much heat really, especially where he is
at least in this particular case the issue is trying to find a way to heat water less expensively than what shore power costs, and there just isn't any way, from a standpoint of energy, energy off the grid is the most inexpensive energy there is for 99% of people, 1% may have a waterfall in their backyard or something

Re: Heating water without shore power?

I've had an on demand propane water heater on one boat which is efficient in regards to propane but used a bit more water since it had to sense water flow before firing up, so the hot water isn't instantaneous. You have to run a bit before the hot water comes in, then you go from freezing to scalding.
My current boat has a generator I run to charge batteries, run refrigeration, make water and is also tied to the water heater so I do all at the same time when it's running. But of course this uses more diesel.
The most efficient was one of my first boats, it had a solar shower bag you laid in the sun to heat up but I guess it wouldn't be too good in northern winters.
Depends on what you can get more easily, water or fuel.
