Hi, I hope somebody can help before I go mad. I have spent the weekend and most of today trying to sort my CH out. I have a 10 rad (4 up, 6 downstairs) Ideal combi logic 30 system. the boiler is 18 mths old and touch wood works fine. Hot water v good in a 2 bathroom semi.
The problem is that some rads are very hot, some warm, some cold. Having read a number of forums, similar problems appear to have been sorted out by balancing the system or flushing out rads. I decided to take the bull by the horns by draining the system, removing and flushing all 9 rads and a towel warmer, fitting new TRVs and new other end valves, adding inhibitor and refilling and bleeding, before balancing the system. i.e. as I understand it turning down upstairs valves. Respect to plumbers I thought it was just us sparks that grafted. ha ha
The result of all this graft is not eactly what I was hoping for
Upstairs - Towel wrmer hot before, hot now - bed 1 cold before, cold now valve cold - bed 2 - hot before, hot now - bed 3 hot before, warm now, valve hot.
Downstairs - 2m double hot before, warm now, valve hot (heavier than a drum of twin & earth) - 1.5m single hot before, hot now - 600mm single hot before hot now - 600mm single cold before, cold now, valve hot - 1.5m single cold before, warm now, valve hot - 600mm dbl cold before, warm now, valve hot.
Can someody advise why this is happening and what can be done to sort it PLEASE wibble, wibble I'm going mad
