Hi,
have a Vaillant ecotec plus 831. the past month or so i've had to keep draining water out of the central heating system as the pressure gauge shows the needle in the red zone. i've checked my radiators to see if there's air in them but nopart of the radiators feels cold. No matter how many times i reduce the pressure to 1.2bar, within a day or so the pressure (when cold) rises up to around 1.5 bar.
What am i missing here? not had this issue before. only issue i had before was the complete opposite where pressure kept dropping. (small leak somewhere but cant find it)
any ideas/help appreciated
Thanks
