Last winter, while motoring around, I thought it was a pity that I could not use some of the excess heat from the engine to heat the cabin. I was thinking about something like a car heater, connected to the engine cooling system, that could blow some warm air into the cabin.
Has anybody tried this, or can suggest why it's not a viable option?
I realise the cabin is a lot bigger than a car, but it could help to take the edge off the cold weather.

It would not be much different than the plumbing used to heat the water. You would have to have a heat exchanger and electric fan, of course.
I don't have time right now to estimate how many BTUs per hour (US measuring system, of course) you could expect to achieve, but it would be interesting to see if it is enough to make it worth considering.

Here's a picture of a small unit from Princess Auto, they make them up to 36,000 BTU. Meant for buses and such so not sure how it would stand up in a salty environment.
You're talking about a Red Dot Heater.

West Marine also has hydronic heaters in their catalogue.
I to thought these a good idea whe motoring and with the addition of a small circulating pump could be used at the dock using the water heater as the heat source. The circulating pump could also preheat the engine. May tax the water heater and shorten its life.

To my knowledge these just would tie into the same line you feed your hot water tank.

Lots of great info here. Thanks, Stu, and the others who contributed.
We rarely have a problem with too much cold; it is usually the other way around.

Funny; I just finished installing a heater of this type in my C36 - [url]http://www.heatercraft.com/marine-heater-kit-with-2-euro-vents-complete/...
This one shows the full kit - I purchased the hoses and fittings separately which cost me substantially less...
I installed it below and fwd of the sink and plumbed it in series with the hot water tank.
Works great for us in the PNW.

Excellent feedback/suggestions.
I checked some other forums, that recommended some suitable car systems (aluminium structure and 12v fans).
Cheers

I agree, Howard.
I also suggest that Steve share half his annual Tech Editor salary with you as compensation. It is only fair.

We put a Dickinson Radex hot water heater, similar to the units described by others in this thread, in a previous boat, a Yamaha 30 (great boat). Unfortunately, we mounted it into a bulkhead separating the main cabin from the compartment under the settee where the holding tank, manual pump, and about 15 feet of discharge hose carried waste from the toilet to the tank and from the tank to the pump and overboard. Even though we eventually tried allowing more ventilation into that compartment, whenever we turned on the heater, the fan pushed warm air tainted by head odour (I'm Canadian so that's not a typo) into the main cabin. Sometimes a tough choice, especially if anyone's already queasy. Plan your installation carefully, but the heater definitely did the job for us.
