water in heater kerosene
I have a torpedo heater that has been out of commision for awhile. I recently fixed it and noticed there is some water in the kerosene. The heater works but spits and pops from time to time. The lower the fuel gets the more it pops and spits. At the time i fixed it, the fuel was close to 5 bucks a gallon and i didnt want to drain it out. However there is less fuel in the tank now and i either want to drain what is remaining, or a better solution would be an additive that would disapate the water from the fuel. Does anyone know of an additive that would take the water from the fuel? Thanks for the help

isopropel alcohol, 89 cents a quart at wally world (wal-mart). you can buy gas drier at any auto parts store, but it's the same stuff, just more expensive... :thumbup:

There are some diesel additives that get rid of water. You are probably not talking about much fuel here. Can you drain all the fuel and put it in a bucket?
The water will settle to the bottom and just drain back off the top back into the heater. IF it is cold enough were you live that water, fuel in a bucket the water would freze solid and then you could easly seperate it.

By the way I heat my shop with 2 of those torpedo heaters and I burn diesel fuel in them. Diesel here is $2.35 and kerosene is $3.79

NEVER use an Alcohol based water remover in heater fuel!

Now after having said that I must admit that I really don't know for sure why not but I have seen several warnings in safety bulletins about doing this and they had an emphasis on "NEVER", also I remember seeing a warning about Alcohol causing damage to the rubber parts in the fuel pump (this was in the manual that came with the heater).

how good are these heters? i have a small shop 20x18 but not insolated yet will do that when i get my taxrefund

I have a 30x40 shop and it is well built in that there are no holes or gaps. It is not insulated at all and no ceiling. Just the peak and you can see the ridge vent, so a lot escapes there. I have 2 of those heaters both 110,000 BTU. I have a inline 110 volt thermostat for them and it will get warm enough to work in a T shirt no matter what the outside temps are. You have to be carefull with carbon monoxide with these heaters. If I work in the shop all day Sat and Sun, Monday I will have a bad headache. 3-4 hours at night does not seem to bother me.

I siphoned all the fuel out i could and added fresh fuel. It still pops but not as bad as it did. I guess i didnt get all the fuel/water out or there is something else wrong causing the popping. thanks for the help.....

Go to any store that sells kerosene heaters and fuel. You will usually see kerosene fuel dryer there AND it comes in beautiful scents like pine or whatever. You don't need much additive, only 1 oz. per 10 gal of fuel.

However, to be honest, the additive is mainly alcohol. Alcohol has the unique property that it absorbs water AND is soluble in oil based fuels such as gasoline, kerosene, diesel, etc. So I would go to Wally World and pick any fuel dryer you see on the shelf. Use the proportions on the bottle. You may have to give it several doses to get rid of the water but it will work. I would just add it to the fresh fuel. That way you can do it once and each time you add fresh fuel, you will remove a little more water.

If you want the fresh smell of pine trees every time you fire up your heater, use the kerosene dryer made for that purpose. I might add that the scent is subtle. No one will ask if you just came from the forest but they will notice the kerosene smell :)
