Propane Force 10

Years ago I installed a Force 10 diesel heater on the boat with a pressurized tank. I remember it being difficult to light requiring an alcohol pre heat, but the real thing that I did not like was the resultant smell of diesel. I used it for a few years before switching to propane. At the time the Force 10 people had a conversion burner that was simple to install in the heater and to this day it works great. I ran a line from the vented propane tanks used for the cooking stove to the Force 10 heater and got rid of the little diesel tank. The 1 inch exhaust line of the heater never did get cherry hot as I think someone else here experienced, but it does keep the cabin fairly warm in 20 degree weather. I do use a pella fan above the heater to help distrubute the heat.

I have had to become an expert in its repair and maintenance. I am profoundly bummed that they are no longer manufactured and you can't get parts anymore really. I've been told that by Fisheries Supply here in Seattle.

Anyway, my heater works absolutely great! I have a digital CO detector onboard and it never budges above a reading of "0". My alcohol stove causes condensation and CO to raise a little, but not the heater.

Anyway, I burn biodiesel in my Universal M40, about a 75% mixture give or take. I tried to burn B99 in my Force 10 and let me tell you, definitively, it does not work. I primed the hell out of it, with several cup fulls of alcohol, and the biodiesel just does not get hot enough to not smoke like crazy. Let me tell you, I filled my cabin with smoke several times trying to get biodiesel to work. Then I tried B20 and it was better but still smoky and obnoxious. Finally, I bought good stove Kerosene, and she burns clean, clear, and hot. No soot, no smoke, and no problems.

I don't have, or want, propane on my boat (Boom), and so hope to keep this stove going for a long time.

My two cents.
To Aeolus Gulf 32 Friday Harbor.
I have a Mercator 30 in Deer Harbor. The boat is equipped with a Force Ten Kerosene cabin heater which works like a charm, but one of the burner tubes has a hair crack in it resulting in a small blow out flame. I have tried to find a replacement burner, but no luck thus far. Any ideas? Eileen B. Deer Harbor

will the small brass force 10 diesel tank last through the night?

Hello Alexbir,

I saw your post on the heater talk last year. I am about to buy a Force 10 that seems to be similar to what you are describing. It is fed by a fairly small brass tank - maybe half a gallon (2 litres) and it is pressurized with a hand pump.

Will this keep going through the night?
Will that volume of diesel/kersosene last 6-7 hours? How many times will the hand pump need to be re-pressurized through the night?
