No it's not been disconnected since the boiler was put in about 9 years ago.
Since we last drained more water out the pressure has stayed at a normal level, so hopefully it will be okay until we get the radiators back on again.
Thanks Tomy & Weareleeds for your replies. :wink:
We removed 1 radiator for decorating, and the boiler was fine, but on removing a 2nd radiator the boiler pressure keeps going up to 3.5 bars until we drain water out of the system. (SIME combi). Inlet water is off. Any advice appreciated. :?
