My central heating oil boiler keeps cutting out. It is a Myson Volaire Pressure Jet 50/70. The system was drained when new radiators were fitted, with new pipe routing in some cases. The boiler fired up fine but only ran for a few minutes before cutting out and initially only heated the pipes upto to the upstairs cupboard where the flow and return pipes start to go off to the radiators. I have bled the radiators and after waiting 10 - 15 mins fired the boiler again only for it to cut off again. The pipes are heating up further along the flow on each occasion I go through this process but the radiators no longer release any air when bled. The boiler runs for approximately 4minutes each time now. Also there is a thermostat ranging from -15 to +10 (never seen that type before). what should the setting be? Any advice would be greatly appreciated.

Hi Xenon: Oil is opened completely and is def getting to it as locked out when no oil got through. Where can I find the filter? Is it in the header tank and how can we check it?

Are you sure the circulating pump is on and working?

Some plumbers fit a by-pass , as a length of pipe with a stopcock in the middle, close to the boiler beteeen the main flow and returns, instead of a proper automatic by- pass valve. This allows heated water to return direct to the boiler which then shuts down on it's thermostat, before any hot water has got around the system. I've come across this hundreds of times. Feel your return pipe close to the boiler, and compare with further away, if it's hotter close, this may be happening, in which case close the stopcock a bit more and get a 'real' by-pass fitted. It' could also be many other things, but this matches your symptoms.

1) call someone to fix it.
2) go out in the hot sun.
3) close all the fans,Air Coolers and any thing that brings cold air.
4) get a new boiler.

Does it have a 'thermal coupler' like gas boilers have? This is a problem I used to have on my old Vulcan Continental' and is a relatively cheap and easy repair.
Hope this is of some use if not, good luck from other serious answers.

Are you sure that the boiler is getting sufficient oil,? I suspect that there may be a blockage in the filter at the tank (water ?)

Check you have water in the header tank - I bet its empty because the valve was not turned back on or the float is stuck.
Re-bleed and try again.

could be that the thermostat needs replacing. Give the manufacturer a call for advice, failing that, I guess you will have to get a plumber in
