I cannot get my (admittedly ancient) Myson Velaire CH & HW boiler to run...and we've now been without heat for about a fortnight (the coldest fortnight for the system to fail!)
The final section of the oil intake tube is transparent so I can see the air bubbles, but despite many many attempts to let the air out via the bleed valve on the top of the unit where the oil is taken in, the boiler just Locks Out. Sometimes even while I've got the bleed valve open.
It's a tedious process as there's a time delay before the reset button operates again.
Are there any shortcuts to this, or indeed overall solutions to the problem?
Any thoughts on why there might be air bubbles in the supply in the first place?
The oil is running freely, and there are no obvious leaks on the supply pipes (at least not on those that are visible)
