just saw the new argos catalogue. they are doing something called a ' Landscape flueless gas fire'. £399. it is glass fronted and they say is 100 percent efficient. also it needs no flue and no chimney.
they also say the room its used in must not be smaller than 27 cubic metres.
what happens to all the nasty gases we are warned about that are normally vented up the chimney i ask my self. would it really be safe in a tiny front room in my tiny terraced house?
