heating oil


Is it possible fot heating oil to get to thick that the furnace wont come on? It has been below freezing for a few days and haven't used the furnace, now it won't come on. Been using the wood stove.

Unless you are in Alaska it doesn't get that thick. DO NOT press the reset button more than once or it will fill the chamber with unburnt oil and create a huge problem!

Yes it is.

Oil can start to jell when ever the temp frops below 20F.

But, most tanks get exposure to the sun during the day, and won't jell until it gets to around 10 for seveal days.

You may want to add 20 gallons or so of kerosene.
Or get fuel additive, and put it in.
The additive may take several days to work, depending how thickly the tank jelled.

What he said. It *CAN* gel and cause problems. Usually the first place it gels is in the supply line, not the tank.

The easiest/cheapest solution is to cut the fuel oil with a couple of gallons of kerosene which has a much lower gel point than #2.

This is also assuming your tank is outdoors and above ground.

Adding to the other replies. If the supply valve is at the bottom of the outside tank try putting a heat tape on the oil line around the valve. I have even used a 100 watt light bulb and a blanket. Then try it in about an hour.

Just went through this on new years day, fuel oil jelled up, and supposely the fuel had the additive in it. Disconnected at the filter inside, didn't have a drop. With the help of a blowdryer, warmed it up faster then I wanted it too. The tank is located outside, fuel line running off bottom of tank, exposed. Now line has electic warming tape wrapped on it.

They use a 2" black iron pipe from the tank and lots of pipe wrap in Northern Manitoba. I don't think the tank gels up badly but mostly the small supply line from it. We have lots of mobile homes with outdoor tanks that don't see the sun for days up here and it gets to -40 occasionally. They may add some kerosine to it at the refinery for us?

More then just kerosene added to it.

Kerosene would jell at -40.

Ayuh,...

I would imagine that what you're buying as Fuel Oil,...

Is Kerosine.....

When I was in the Bis many years ago in Maine, as well as now dealing with my own properties,...
If the storage tank is Outdoors,... You can run #2 til Nov. or Dec..
Then start buying #1 til March.....
Gelled fuel will Never be a Problem.....

Btw,... The Only downside to #1 is the Price......

Could not have said it better my self. except the Ayuh part I would have said UG but then I'm just an old hillbilly Farmer who got tired of milking cows. The other problem may be condensation is the filter fresh

Get 10 or 20 gals of kerosene in it before you get another cold wave.

We in northern Ontario, for an EMERGENCY fix, add a pint or so of Methyl-Hydrate. Then followed by a litre of diesel conditioner(Antigel). Wait up to a half hour for the Methyl-Hydrate to work, Bleed the line to see if the oil is flowing then Presto.! We get 10 to 15 no-heat calls a day when the temp up here drops below-25 celcius. Hope this helps.
