Marine Bulkhead Heater Review

Cozy Cabin” by SIG Marine.


We've reached the threshold of freezing nights so I've been able to evaluate the recently installed Cozy Cabin Marine Bulkhead Heater.


These small (8” x 8” x 16”), lightweight (11 lbs), sea-worthy devices have heated watercraft cabins for decades. They can be ordered as either liquid propane gas or diesel oil fuel. The stainless steel and brass build quality and finish is exceptionally fine.


No electricity required. It has flame out and oxygen depletion sensing. Exhaust is vented to outdoors. The control valve operates similarly to that on a stove-top. Push button peizo to ignite. Fuel consumption is 10 hrs/lb at low, adjustable up to 4 hrs/lb at high. No fan, perfectly silent.


The manufacturer states that no heat shield is necessary unless you are mounting it to a painted or vinyl plastic wall. I made an .040 5052 heat shield that stands off the original lacquered ash plywood bulkhead with 1/4” airspace.


The heater shown is installed in a 1968 Globe Trotter, in compliance with manufacturer's clearances to combustibles.



The size, shape, and observable flame offers the ambiance, warmth, and camaraderie of a little pot-belly stove.


I chose this heater over the Dickinson because it's smaller, very well reviewed by sailors, has a 4” x 5” cast iron cook-top, operates without electric, less ominous air/exhaust pipe, and met the parameters of BTU calculations raising inside temp 40 F degrees higher than outside.


It has not excited the smoke, carbon monoxide, or propane gas detector.


It has never deployed its oxygen depletion safety shut-off.


It is neither child nor idiot proof.


The Dickinson 9000/12000 is a safer design, and warmer.


I made a whale tail porcelain teapot to fit the cook-top.


The Cozy Cabin functions well, pleases the eye, and proves its name.

Had a Dickinson diesel fired heater from boat. Worked beautiully but did require 4' stack and was larger than aluminuminum's. Never a whiff of diesel smell. A nice comfort. Propane looks like it might be a nice solution as well!

I have seen those heaters on Yachts before as well and i think they look need.
Now, i have noticed the very nice interior of your globetrotter. Any more pictures or a restoration Thread?

Thanks Stefan, for the positive acknowledgment. I like your mission statement... I hope you do save them all.



I never started a restoration thread, but I have kept an extensive photo archive of about every facet of my remodel for nearly four years. How time flies when you're havin' fun, eh?


Nearly done with my “Airstreamesque” range-hood /LED valence/shelf/back-splash for the kitchen, so I will eventually post more detail of that adventure.

Very nice job on the Cozy Cabin Marine Heater install. Absolutely superb workmanship! Thanks for the review.

Aluminuminum--great photos, incredible craftsmanship. You are insuring this creation, right? I like the shoji door, as well as the English-wheel-made canopy. Look forward to more photos.

We had a Cozy Cabin propane heater on our 32' sailboat years ago. While some people bemoan the fact that they contribute to an increase in humidity within a cabin we never noticed it and loved the heater.

ALUMINUMINUM, where did you get the really nice ss back piece you used in your insulation. I've looked and can't find anyone selling it.

Thanks,
RobertC

I sawed it from a sheet of .040 5052 aluminum.

I'm curious. After using the cozy cabin for a year, what are your thoughts. Do you still like it?

It's all good

So far, its operation has been flawless, ignites easily, very reliable.
No condensate issues. It adjusts manually like a stove-top burner, low to high.

On a 40F degree day, it warms the cabin from dead-cold to exceeding 80F degrees In a half hour. It's installed in a small trailer, and we've never camped in continuous freezing weather... Old Globe Trotters, Bambis and Caravels didn't have forced air duct-work to heat the tanks like the larger trailers did, so the Cozy Cabin cannot address that issue. Generally speaking, we folks from the North don't usually seek freezing camping conditions, so I may never review a sub-freezing experience with the Cozy Cabin, as I have zero inclination to camp in freezing weather.

That said, it's very comforting to have an open fire in the cabin, and aside from the nearly inaudible whisper of the burner, the heater is perfectly silent. Its ambiance is of a little pot-belly stove. With its cast iron cook-top duality of function, it assists in preparing coffee, tea, or a can of PORK.

At its highest setting, I observed the following temperature values.
450F... cast iron cook-top,
140F... stainless steel belly,
145F... exhaust pipe,
100F... ash plywood bulkhead behind/next to exhaust pipe,
150F... entering ceiling collar.

The material, and workmanship are top notch. It is truly “seaworthy” quality.

I am very pleased, Yes, I would recommend it to a friend...
