Rising boiler pressure on CH.

[wsduke33]

I have a Vokera linea plus combi-heater. The central heating has been off over the summer and when I have come to turn the CH on the pressure keeps rising well above the 1.5 bar level it usually runs at.

The level has risen to just short of 3 bar when I decided to turn the CH off as I could see there was a problem.

Also, the downstairs radiators are hot at the top and cold at the bottom. Are these things connected? Any ideas?

Your expansion vessel needs pumping up by the sound of it.

Do a search.
