Hi,
I hope one of you lovely people can help?
I have a new Ideal Logic Heat 15 condensing boiler with a new Honeywell actuator and a 17 year old Wilo Gold TF110 pump.
HOWEVER, the problem that I have started when the old boiler was there, so I doubt the new boiler is to blame.
The hot water works fine.
When the heating only is on, I only get heat to one upstairs rad (none downstairs) and then it slowly goes cold again about an hour later (with heating still being on).
As per various tips online, I've tried opening all lockshield valves to see if it helps, and also tried closing all but one lockshield valve, tried closing the upstairs ones only etc etc but to no avail.
If I completely turn off the one radiator that does work it makes no difference to any of the others.
Also, when I turn the hot water on, I get full heat to one upstairs and one downstairs rad for about half an hour but then they go cold soon after too. (Again, I've tried completely turning those ones off but there's no difference to any other rads).
They've all been bled too (there was no air in any of them anyway).
The pipes leading to the non working rads are completely cold too (if that helps diagnose anything?)
I am now lost as to what to do next!
All the rads have TRV's too (except the towel one in the en suite) and there's a room thermostat in the hall.
Any advice for this poor cold female will be much appreciated!
Thank you
