Re: propane furnace opinions please

Thanks for all the input I guess I forgot to include the part about this being for the new to us boat a 42 ft Spencer built in Canada and well insulated also already have propane on board with two 30 pound tanks. Also I worked HVAC for many years on houses and am a retired shipwright the unit in question was priced at just about 1500 for install kit as opposed to the wabasco diesel unit at just under 3 k. I just have never installed one on a boat and dad doesn't want a bulkhead unit has to be forced air also what would the units do to the potential resale value would the diesel increase the value enough to offset the install cost any

Re: propane furnace opinions please

I would heartily recommend the Dickenson Propane unit . It comes in two sizes ,the larger ,which have puts out 12,000BTU on high. It heats my Freedom 33 with now problem, the unit also has a fan that is adjustable and helps distribute the heat. I generally run on high untill boat warms up(about 15-20 minutes ) then turn it down to maintain heat. While I agree that propane has a low energy densiity these units are quite efficient and my two 6 lbs run my hot water and stove too yet Ive never felt like I didingt have enough propane. I live aboard and run the unnit continuosly when aboard and I have to switch tanks about once every weeks. Im adding a deck mounted 20 lb barbecue size just for the winter so that should last atleast a month.
The other real nice thing is the "AMBIENCE" it is truly wonderful too curl up next to the "fireplace" with a book and a cup of Pete's Coffee !!

Re: propane furnace opinions please

The Dickinson P9000 or P12000 are good safe units for boats but not great for liveaboard boats. Their fan is hardly able to distribute heat to a V-berth or after cabin.

The best units would be forced air from Wallas, Espar, or Webasto with the Wallas being the quiet one. All 3 are thermostat controlled forced air furnaces suitable for a boat of 42'. Call Scanmarine in Seattle for your options. If the budget is higher look at a hydronic system from Espar but expect 8 - 10k pricing.

Re: propane furnace opinions please

Brian the budget is rather limited right now just bought new technotics holding plate freezer and refer unit likely will do a Wallis but may not be able to afford it until next summer before going to Alaskan waters and the bulkhead units are not possible we would either loose part of dinette and that berth or loose the two sea berths on the port side and that is not an option so forced air is the best way to go.

For a Spencer 42 I agree.

Re: propane furnace opinions please

Our Wallas forced air furnace does a great job in our 40' pilothouse. Just spent three days in sub freezing temps and it was toasty warm. You won't regret going the diesel forced air route if you are going to use the boat in cold weather (or even in warm weather/ cold water). Scanmarine is great to work with for DIY installation.

Re: propane furnace opinions please

Yup, a Cal and and a Spencer 42 are a little different. Minor details.

Diesel forced air.

Re: propane furnace opinions please

Newhaul.. it wasn't totally clear, to me, anyway, that we were talking about your Dad's boat at first. Like most, probably, I saw your avatar and made assumptions

Seems the consensus for a boat that size, is diesel forced air (or diesel hydronic). Not the least expensive options but if you go the 'truck source' route I think you can do pretty well comparatively speaking.

An old-school diesel stove/bulkhead heater would probably do a good job of heating the main cabin but warming the ends of the boat would become an issue, I think.

I don't think a 'inexpensive' propane fired unit that the insurance company might balk at is the final answer.
