One room in my house (well actually it's two rooms & a tiny bit of hall at the moment but the wall between them might get removed) is about 20' long and 9'6" wide. One end of it and an L-shaped part of the middle of it is currently the kitchen, with a door (in the middle of the end wall) leading to the garden.
I'm considering having the kitchen moved to another room in the house and having about 5' of the 20' space, at the end which has the garden door, turned into a small utility room - washing machine, tumble drier, sink, pulley etc).
The boundary between that and the remaining 15' x 9'6" space would just be a stud wall (or perhaps a little stronger if necessary) with a doorway in it at one side and a window at the other (I already know the window is a complication because the stud wall will bisect an existing window opening so that will need a fire-proof pillar put up through it so fire can't get around the end of the stud wall. It means that on both sides of the new stud wall there will be a small window (unless either or both of them get bricked up completely, though as the house is harled it's hard to see how that could be done without looking awful on the outside).
Is there any way that a gas fire could be mounted (perhaps in a fake hearth) in this stud wall? There'd be no way a chimney could be put in, at least not one going straight up (through the middle of the room above). But could it somehow vent horizontally (along the line of the stud wall) to the outside? The horizontal distance involved would only be about 4-5'.
If a gas fire's not possible, I presume a wood stove could be used (as it's not unusual to see a stove pipe crossing a wall) but I don't really want a stove. Of course there's other options - fake fires with fan heaters in them etc, but I don't really want one of those either.
