we've woken up to a cold house in the last few mornings and when i checked the time on the boiler dial it was a few hours behind what it should be, hence the timer didn't click in to heat for early in the morning. Don't have a model number but it's a Firebird oil boiler and it's approx 5 years old. Can anyone think of a reason why the timer dial would be losing time?
Usually such timers have a backup battery to tide them over if the power is cut. But maybe this one doesn't or the battery is faulty and the power was cut for a few hours at some stage? Or maybe it's just faulty altogether?
Would have thought that the losing time aspect was pretty unusual though - I thought basically these things either work or they don't as they are mechanically/electrically very simple?
Maybe the original poster can clarify if the timer is actually losing time after being set to the correct time and, if so, at what rate? Or if the power outage hypothesis might be correct.
This happened to me last winter, the timer spent a couple of weeks losing time, and then started jamming when it reached the 'on' sections.
Landlord replaced the timing unit and that sorted it out.
thanks for the replies. Definitely did not have a power cut. Thought initially that the kids were getting at it but it was correct last night when I went to bed and when I checked it this morning it was 3am by the timer. Went to bed around 11:45 and was downstairs at 6:30. Looks like it might be shot so. I would have thought that these things either work or they don't - not gradually begin to fail.
