Mi,
I completely agree with you. Electric is the way to go for both safety and
convenience. I would not have gas unless CNG was available everywhere and
there is the rub. It isn't. The gas of popular choice is LPG and that is
heavier than air. CNG is not. So for me, the best of the rest was electric.
The other responders mentioned the impractcality of using 24V for heating
and cooking. They are correct. In order to be all electric, you must use
240V. Even 120V is impractical because of the wire size required. You need a
large generator, in fact you probably need 2. That means a big boat. The
other problem is the noise from a running generator. I have overcome this
problem with a shaft driven 6KW generator that is silent and a 35KW diesel
generator, but then I have the space. Please be careful of capturing heat
from your engine exhaust. Yes, it is possible, but if you take to much heat
out, you will create acidic deposits that will destroy 316. If you use a
fresh water exchanger and your hot water tank is up to temp and you continue
to run the engine, the exchanger overheats. So you need auxillary cooling,
when your heat demand is low. I guess there is no free lunch.

On my new boat I will have a powerfull 24VDC battery bank charged by a
diesel generator and auxiliary sources.

I did a bit of search but couldn't find much- are there any 24 VDC
appliances such as cooker/oven, fridge, AC and water heater you could
recommend?

I know I can run standard items through power inverter but I would
prefer not to do it for the sake of reliability/efficiency/cost. I wantMi,
to go totally electric (no gas)

Regards Mi
