So I’ve been having this issue with my boiler for a while now, I’ve currently got one stat in the hall that when I turn it on it brings the heating on. Very basic, it’s low voltage switching. See when I turn the heating off it takes ages to go off, it’ll heat the radiators up to absolutely boiling temperatures and it’ll also turn itself on when we are out and the house is absolutely roasting hot when we come in. Now a tried fitting a new stat and the same thing happens so I know it’s not an issue with that not isolating it, any ideas?
