Vokera Compact 28SE losing pressure when CH turned off. No obvious leak from PRV. Both boiler exp vessel and second additional vessel checked and recharged. Under floor inspected. Leak found and repaired on compression fitting. Problem persists. ?heat exchanger fault. Boiler hasn’t been isolated yet and left to ensure issue is with boiler - presume this is next step?
