when i turn my heating off at night some times it does not switch off .it stays boiling some times when it does switch off it some times it switches on in the night i have a boiler out side but controls inside
if it has only started doing this recently it is probably the internal frost stat doing its job and stopping your boiler from freezing however as you have given no information about the boiler and system this is just a guess
