I have a gas boiler ( oldish Potterton netaheat 80e) on a conventional gravity fed central heating system.
Small house, original system had 7 rads, then built a rear extension (single kitchen/dining room) and added a new rad, the problem is it has never really gets hot.
Now, I have been through all the usual stufff of bleeding air and balancing, had at least two plumbers over the years fiddle with the balancing, small improvements but still really to no avail.
Since added a small front Porch extension with another rad and this gets piping hot like all the other rads.
I think this problem rad is the last one on the system ( if that makes sense) and it is also the largest rad, could these things be a factor? , and what about the bore of the pipe supplying the rad, could that also be an issue?
Obviously don't need the heat just yet, but I'm sure in another month we will be feeling the early nip of winter,
Spent so much on additional electric heating last winter that I really need to get this sorted, just hope I don't have to go digging up floors to replace pipes or something.
Just wondereing if anyone out there has ever had similar problems?
Cheers
