I'm really cross!
Having been patronised by engineer earlier, OH just tried the same tack until I exploded!!
The whole point about thermostatic radiator valves is that you can set each room to be what you want- am I correct, or not? Also, moving the main control into here would be 'b' stupid coz this room would get warm, like now, boiler switch off & rest of house be cold. 40yrs of having control in hall, just as everyone else on road, works fine. Not my fault the stupid new fangled boiler doesnt like it.
Anyway am trying reverse tactic re the valves & we'll see if the boiler adjustments made over the last 2 visits have worked. If the 'kettling' starts again, then shall alter the valves' settings until it sorts the problem. Shant hold my breath.
Right, rant over. Need to order a Tesco delivery, or may just flop & try to chill out. J.
