Can you please advise what to do or what is wrong with my Linia 24 .The heating system is turned off but the pressure guage keeps going up to 3 bar,I release the pressure down to 1 bar and after about 12 hours it climbs back up to 3 bar.I have disconected the loop fill to see if the top up valve is leaking but it looks O.K. Can you please advise

If you turn your boiler off totally and the pressure is rising even when you have the filling loop disconnected then you are looking towards new plate heat exchanger.

If it rises without use you have mains cold entering sealed system side of boiler. if its not through filling loop then its via an exchanger.

time to get someone to look at it me thinks

If the Filling loop is disconnected when this is happening it means you need a new expansion vessel.
