Thanks for the reply...
I've got 11 single rads in the house....is the performa 28i enough for this?
How much would an extra expansion vessel cost to put in place? and would it need to be done before a powerflush or could it be put in place later?

First post for me here and ive done lots of looking around the forums for a solution to my problem with the boiler.
I brought a new built house around 5 years ago with a new Potterton performa 28i Combi boiler.
A few years ago i noticed that the pressure was going down to 0.5 bar...
