We had a real fire in the sitting room when I was young and one of those electric fires which are supposed to look like real fires in the other room, but it wasn't until later that the real fire was changed and radiators put in which were warmed by it. Before that we used to have paraffin heaters in the bedrooms, and my word, it's a wonder I was not in a coma. Just one whiff of that now takes me back!
