I've had probs with a clients oil fired boilers....he has two of them. One had stopped as the fire valve needed reseting, there was no sign of heat in the outside storeroom where the boiler lives, so don't know why it needed it.
The other has no flow through the tank filter. Going to change filter in the morning.
He asked me if the oil lines can freeze, and I said I didn't think so, it would have to be about -20, but I could be wrong??
While we're on the subject, doesn anyone know how much a pressure guage (for setting the pressure on the pump) would cost and where to buy from?
Also can you swap burners, only I have a spare burner that is the same KW output and could just swap them over while I clean the other one up...
I don't really like working on oil fired boilers, as gas is more my thing. Have had some training though with a Oftec engineer, so know enough to be safe.
