hi
I've just upgraded several of my singles to doubles - kick out a lot more heat & now nice and snug
However, it has occurred to me that these may be a bigger draw on the boiler & therefore more expensive to run.
Is this the case or are they just a more efficient use of the heating system ?
thanks
