Does anyone know 'owt about Room Thermostats?
My house has got one of those old electromechanical ones, and this year it seems to be less than enthusiastic in terms of automatically switching from an off state to an on state, and vice versa.
I'm thinking of replacing it with a new-fangled digital one, with a programmable timer etc.
Is this easy? Is there anything that I need to worry about?
If it all goes tits-up, should I call an electrician, or a heating engineer
