I have a 12 year old Ideal Classic Room Sealed Gas Boiler and, upstairs, a hot water tank with 2 motorised valves attached. These are ACL Lifestyle 2-port valves with an A-B switch on each (set to A). Both the heating and hot water are on timer (heating permanently off for summer just now though). Occasionally, although no doubt it will become more of a problem, the system can be heard to be working outside the timer hours. This is especially noticeable upstairs with the sound of whooshing water. The boiler itself clicks and ticks although it's usually just the piot light you can see. A few nights ago I just turned it off at the mains and when I turned it back on again next morning (outside the timer hours) the boiler lit up before eventually reverting to just the pilot (although still making noises). For the last couple of days there's been no problem but I'd like to ensure it stays that way.
Can anyone suggest what the cause(and the cure) of this occasional glitch is? Many thanks indeed.
