How wise it it to burn propane in an enclosed space albeit with a slightly open companionway?
Propane undergoes combustion reactions in a similar fashion to other alkanes. In the presence of excess oxygen, propane burns to form water and carbon dioxide.
C 3 H 8 + 5 O 2 ⟶ 3 CO 2 + 4 H 2 O + heat
When insufficient oxygen is present for complete combustion, carbon monoxide and/or soot (carbon) are formed as well:
2 C 3 H 8 + 9 O 2 ⟶ 4 CO 2 + 2 CO + 8 H 2 O + heat
C 3 H 8 + 2 O 2 ⟶ 3 C + 4 H 2 O + heat
Does your CO2 or CO alarm sound off?
Appears that CO2 and H2O are byproducts - condensation & suffocating gas.

Kimberlite came with a couple of blowers mounted under the port coming in my port locker.
I was hooked to ductwork to blow fresh air into the aft cabin, the main cabin , and the forward cabin.
It was very easy to hook an Espar heater into this system as the ductwork was in place. I don’t know if the 54 was supplied with this option.
If you do not have these ducts, then I agree that hot water with blowers is the way to go.
I think you will find pumping the fuel into the tank a lot easier than using fuel nozzle. You also do not get air into the bladder.
In the interim If you turn on the stove and open the companionway a crack it heats up the main cabin nicely.
Some old timers used to use red clay flower pots over the burners to act as radiators.
I am off to Kimberlite on the 12th and will return on the 21st
I'm not sure what you mean about a forced air system.
It was cold north of the gulf stream. I had a small propane heater for the trip. It worked but it was a temporary solution.
That bladder looks like the same one I have. I got it from Roberto.
