The family has noticed major interference on the TV when watching digital channels at certain times when the central heating boiler is on. By trial and error, I have discovered that the diverter valve is making a ticking noise when both the central heating and hot water are on. This ticking (Hope it is not sparking) is causing the interference, and it does not occur with just heating or just water heating. I could get by, adjusting the hot water timer to times when the heat is not on - but should I be getting it replaced? Is the replacement just an electric motor which I could replace myself, or are the motor and the valve integral, so I will need a plumber to drain the system and do a full replacement?
