Hi: Our Ideal Isar HE30 boiler which is approx 4 years old is situated downstairs in an outside out house at the side of the house. Recently, the radiators heat themselves up even when the timer switch is switched off and when on automatic it goes over and above the set temperature and comes on sometimes when it is not timed to do so. We did wonder if it was something to do with the frost settings and it being cold where the boiler was,
Prior to this we had no problems in the previous cold winters.
would be greatful for any ideas?
