I am not Stephending (that includes the Pethericks), however I know from personal experience that heating old buildings can be a tricky issue, in particular when you have to maintain some historical elements. Even worse when you have high cielings and monumental staircases, that would be the Pethericks case, not mine, and neither SJ's: her place has farmhouse dimensions, with those low cielings, which should make heating easier. So, there is a difference between nearly freezing, and heating just enough to be confortable wearing thicker winter clothing (which is fine for me). In SJ's case there seems to be a major problem in the whole heating system, she should scrap it all, and start again, she would have the money for that.
