guys I am just interested in what would be your plan of attack on this one .

Large house, the home owner inherited this problem so we dont know if its been like this from day one ...
I am incredibly busy and dont even want to do it ..

18 ish rads , 35 kw vokera bag of shi* system boiler . 3 rads furthest away form boiler dont heat up .

No stuck trv pins , open l/s , shutting other rads of doesnt seem to make any difference .

I put a new pump in a fortnight ago , no difference.

As said just interested in where you would start. Go for it lol

Thanks in advance .

Pump too small 25-80 pump needed

Also bet the expansion vessel is too small around 20 l needed

New boiler and powerflush. Old non return stuck?

Easy way to tell shut 5 rads do the others heat up ?

Vessel wont make any difference to rads not heating, pump is genuine Vokera , so I dont really want to put another one in , but have no idea what size it is to be fair .

Zone it. Pump on each zone.
