Boiler empty 😎The boiler always "kettles" on starting up too.
Maybe sammathias has a point, it could be as simple as that. What is system pressure? Is there flow from a vent point on the boiler, or the pipework close by?Fixitflav - and that is what I don't get... Seems to me like perhaps I do have a circulation problem a bit but def no blockage as such. And it feels like the boiler is just too picky about the conditions it will operate in. Thinking the only way to tell for sure is putting a flow sensor in, on the return by the boiler? Could just be that I have some circulation, but very limited, the pipes are 35 years old...
The system should have a number of manual air vent points, usually just a knurled nut to open. The one near the boiler will give some idea whether the boiler is full. Water should flow from the vent.Wasn't sure I understood the question about flow from the vent point on the boiler?
There’s your problem. You need a heating engineer and not a plumber mate.Thanks. I don't think I am capable of fixing it, I know I am not, just looking for some creative ideas and to learn a little really. Had two different plumbers out so far, 4k spent and the system is behaving identically, they tried all the "simple fixes" apparently and some more complex ones. Really appreciated the responses and ideas.
Tried to take some pics last night and all the useful bits are blocked by the big red pressure ball thing from the sealed system! Will try again or draw it down later.
Good question.Oooosshh. How many copper pipes do you have coming from the boiler itself?
I think that's the least of his worries.no bypass ?
22mm equal tee before the pump what is that for ?
