Besides for the danger, those 1 pound bottles would not last long at all. We had a solid fuel heater on a wooden ketch we used to have when I was young. It was nice on a chilly morning.

I don't have diesel on board and my early 32 doesn't have a propane locker. Seems you can run these things off of 1lb disposable tanks but if I'm reading it correctly, they must be located outside or in a propane locker (which I don't have). I suppose it's not safe to have the 1lb propane tank inside the boat eh? What have other non-propane boat owners done? The hot water engine heat is nice when you're motoring now doubt, but we like to spend days at anchor and we're looking to extend our cruising into the fall next year.

The way the A4 works the heater is in the heat exchanger loop after the thermostat, so it is not providing “extra” cooling. The A4 does not have a separate heater loop like many diesel engines (and car engines for that matter).

Calypso’s Perkins 4-108’s T-stat controls the flow of coolant through the raw water/coolant heat exchanger providing the ability to operate at the desired 180F. If another heat exchanger is added that is not controlled by the engine T-stat it may be possible to remove enough waste heat to prevent the engine from reaching 180F. When originally looking at how to heat Calypso’s cabin it was clear we would need at least two Red Hot type heat exchangers. I don’t recall exactly who brought up the issue of removing too much waste heat but it was likely one of the diesel mechanics that has worked on Calypso’s 4-108. I expect if we were running the 4-108 at 80% to 90% of capacity there would be plenty of extra heat available. Our typical fall/winter use of the auxiliary engine is motoring for a short distance in calm conditions using less that 50% of the available horsepower. I expect that a Red Hot could be plumbed in between the T-stat and the engine’s heat exchanger or have its own T-stat added if a cool running diesel engine became a problem. As Joe indicated the A-4 and other gasoline engines do not seem to have a shortage of waste heat. Diesels really prefer to be in that 180/190F operating temp range. Any day now I will be covering up part of my Cummins powered pickup truck’s radiator as my commute drive is too short and too slow to allow the engine to hit full operating temp and the local Rozzers frown on my need to speed in the interest of getting that Cummins up to temp.

Frerker Subject: Re: Stus-List Cabin Heat Don't these marine engines have thermostats that open/close to keep the engine temp constant? If so, then would it be a problem draining off heat since it's only waste heat; the engine will still be constant.
