Boiler NOT Working - Please Help!

A common problem at this time of year is ice formed at a filter at the tank outlet which restricts the flow of oil. Whilst it might be enough to start the boiler it cannot continue.

So if you have a filter there, you could see if its blocked by ice! Not all installations have a filter there!

Bob, lay a "temporary" pipe out from the tank to your fire valve (cover it well to protect it from the frost). You can the get the boiler going and do the digging when the soil is warmer.
Don't adjust the fuel pressure without using a pressure gauge which connects to the fuel pump "P" outlet.
 
you could try a footpump, disconnect affected pipe run . and give it a blast.
 
Before you start all the digging just pour a boiling kettle over the exposed pipe near the house, just in case its only blocked there!

It must be f**king cold where bob the builder lives.

The freezing point of kerosene is -73c. :?
 
think you maybe looking in the wrong place.

when the boiler first fires up is ok for about 2mins before the first lockout. then when reset it gradually gets to lockout more frequently.

if this is the case i would try changing the solenoid first as this one of the most common components to fail.
 
However I decided to check the pipe where it enters the house and the oil doesn't even reach the fire valve on the outside!

In view of the above I doubt that the solenoid could be the primary fault!

Depending on the local temperatures, the oil could be becoming too viscous to flow if its about -10° in his location. Also there might be a build up of ice crystals blocking the pipe.

A kettle of hot water poured over the exposed pipe is a very easy thing to try.

Furthermore its often forgotten that its so easy to rig up a temporary one gallon tank in the boiler room for testing or temporary service. I think there is a Building Regulation limiting the volume of any indoor tank. ( 4.2 Gallons ? )

Churchills bunker has a small tank above the generator to supply fuel by gravity to the engine.
