All the chimneys in my 30s semi were ripped out years ago (not by me) and we have central heating. Mostly it works well but not in our living room, which gets chilly as it has open stairs and the front door in it. Almost more than a bit of extra heat, I'd like some kind of cosy focal point for winter. What are the best of the (cheap) options? Bio-ethanol fires: inefficient? Flame-effect plug-in stoves: naff? Are there any portable electric heaters that actually look nice?
