Heating appears to be on all the time!!

[KEMPY]

Hi

I have noticed in the past few months thatmy heating is on when it shouldnt be. I know this will be too much information but several nights I have woken for a wee in the early hours and noticed my heating is on! Also I have just nipped home from work and again my heating is on. The timer is set for an hour in the morning, then to come on at 5pm til 11.30pm then 12.10am to 12.20am. My boiler is outside in a shed and is oil fired. There are no thermostat thingys in the house. Any ideas what is wrong please. I am thinking maybe the timer is up the creak? Any help would be much appreciated. Thanking you.

LOL - you'll make a plumber of me yet Fuzzy!! Our old boiler used to do this and the house was boiling hot even when it didn't seem that cold outside.

depends where the frost stat is situated, its only for exposed pipes and should come on if pipes are hot, it should be inline with a pipe stat at 25C
