hi guys . got a problem with a vokera compact boiler . the boiler keeps over pressurising and the owner has to drain down the system every day virtualy . i was told it may be the filling loop passing water but have disconnected this and it has not passed water . any ideas would be grateful. thanks.

Impossible to be 100% BUT if you say you have disconnected the filling loop then unless somewhere along the line you either have a cross connected pipe OR you also have a hot water cylinder on your system it only leaves the heatexchanger.

The Vokera Compact uses a combined main and DHE so there is not the normal plate heat exchanger in your boiler.

So as I said unless you have anything 'unconventional' in your combi system nothing else is left!
