I'd like to find out what anyone's experience has been with whatever heat source they've been using. I have used a small West Marine space heater in my small sailboat in the Seattle winters. They suck a tremendous amount of power for the heat provided. I would like a heat source that could work independent of shore power.
I don't seem to find any threads on CF searching for heater or heating systems, maybe I am not searching properly.
Thanks!

As multihull's biggest enemy is weight, neither for a cat nor a
trimaran it makes sense to have huge water
tanks.
Such
tanks same need lots of energy to be heated linked with a hot/cold
water pump. So nowadays you use a
water maker which can cover the daily amount of water in a small tank.
I have learnt from the "tiny home movement", people who have same problem as boaters on multihullers, that a gas therme is the most efficient way.
Here an example from a tiny home house... I have noticed from other boaters, that they use such systems on board, too.
And with
propane you same can hvae a heating
stove...

The benefit is: you have for
cooking + hot water (inclusive
deck shower/bathroom) +
cabin heating the same source of energy:
propane. Most efficient in my understanding.
You can reduce the amount of
solar panels focussing on the energy you need for
electric devices.... and you dont need a
generator or running your diesel
engine (e.g. some use hot water exchange system from the
cooling system of the engine).
But maybe I am wrong... I am in midth the process of my own plans for
buying a
Trimaran. So simiarly to you such questions come accross my own path. - Maybe there is a more eco-friendly solution than using propane ?
Some boaters go the more radically way to use "black bags" as "solar shower". So long you dont have big crews, 4 bedrooms and 4 bathrooms to
service this might work as well. :-)
