Hi All
Vaillant ECOMAX 828E
My boiler pressure varies when heating is on and when heating isn't on. Isn't the pressure supposed to be static at 1.5 bar at all times. Is this variation acceptble or is there some fault with the system. I would be grateful for advice to help me locate and fix the problem (if there is one). Thanks in advance
