I think it is a performa HE 80. To be honest I have always kept the pressure at 2.5 as this is mid way between both red sections and it states to keep at around about 2? It is now showing 3.5?? Not sure why the rads are not working though? Thanks for the reply
Hi and thanks for your advice in advance. I have a potterton Performa He and when I put the heating on a couple of days ago the rads downstairs were cold. I bled all radiators and then turned them all off and starting downstairs tried switching them on one at a time to see if they got hot...
