Megaflow Persimmons Home boiler & pump swith on themselves 3 year old three storey house and the boiler and pump switch on intermittantly by themselves (started approx 12 months ago but getting worse meaning the radiators are hot when this happens - can't switch them off unless I isolate the elec. spur socket feeding the system ! !
Can anybody help - is this a typical problem?- my initial thought is a faulty drayfoss programmer but i'm sure any experts will have come accross this problem before ! !
Would welcome any help please !
