We have ferroli modena combi system which the manual says should have a pressure of 1 bar whilst off.
This is ok and the system keeps this pressure for months, so no leaks etc.
However when the system is up and running the pressure barely moves, maybe it will reach 1.5 bar but no more than this.
All the radiators around the house warm up ok but they do cool down very quickly, so that if we switch the system off at 10pm they are stone cold by 10.30pm.
Just wondering if this pressure when the system is running is ok, or should it be higher and if so what do we need to do.
Boiler located in the attic space, feeding 12 radiators
Thanks
