I have a Potterton Performa 30 HE. Two upstairs radiators need air expelling every 1 -2 days. Is this normal? Last night the pressure kept dropping despite my adding water to the system. I noted that there is water constantly dribbling out of the plastic discharge pipe into the drain with the pressure dropping below 1 bar within 15 mins. I know this isn't normal! It is a repeated problem - even the CH fitters don't seem to be able to resolve it long term! So far we have had 2xheat exchangers replaced and a faulty control panel. Last visit 6/52 ago for yearly service which, amazingly gave us the all clear. I have had to turn the boiler off for now so no C-heating.
Does anyone have any suggestions as to the cause?
