Our oil fired rayburn has started puthering and making a lot of soot (tonight) – could this be due to very cold fuel oil?

bump

Wouldn't have thought so, not unless the oil is below -20degC or so. More likely to be blocked jets or something. Do you have an old nozzle you can fit to try?

No problems here but only about -3 deg C.

shouldn't be a problem, unless you are using 35sec oil (more like red diesel and used on older oil boilers mainly on farms)

The only times I've had a problem is when you get some water in the oil line. Have you got a stell or plastic tank?

Could be coincidence and just that the applinace needs servicing

Been having the same problem here. About a week ago our rayburn stopped overnight so we assumed the oil had run out. Turns out we had plenty oil and the next day had it going again without any probs. Same thing happened yesterday so we're having it serviced tomorrow.

The section of pipe from the tank into the ground is very exposed and has been literally covered in a block of ice. Even though the oil(kerosene) wont freeze until -60 or so, any dirt or moisture drawn through the line from the tank will. I suspect this is causing our problem.

our tank is down to 30% is so i think that may be the issue. Trouble is that the oil co. cannot get int o fill it due to the snow!!
