Throughout house then suddenly the 2 in the front large kitchen/diner will go cold
My Honeywell thermostat control unit is in the back room and because it’s a cold room with high ceilings I’ve set it at 25c
All the rads have those thermostatic controls and all are working and not stuck
The rads have been bled and all were fine
When i tinker on the rads control very slightly the rad will warm up again! Please tell me what is going on or point me in a direction where I can maybe do trial and error or anything
Also I want to service my Magnaclean pro 2( I do it every year) but this time I can’t turn the top lid with the special large spanner, it seems to be stuck fast and I done really want to remove the whole unit as that seems hard too, if I use real force I might bend or cause a leak issue from the adjoining pipes ..... any suggestions guys
Thanks in advance
