How can I fix the hot water and heating problem with my Ferroli Domina 80E?
I have a Ferroli Domina 80E, it is an older combination system. The hot water comes on when the hot tap runs, but switches off and on while running no constant hot water, It works the same way with the central heating and the flame never stay ablaze for longer than one minute at a time.
