Can someone please indicate what exactly is involved when fitting an inset gas fire into the existing fireplace of a 1930's house.
I am removing a free standing gas fire and intend to have an inset type fitted; I already have the restrictor fitted to the floor next to the hearth but once the inset is fitted, how does the fitter connect the gas supply to the inset as I have never seen any external piping?
Also, how efficient are inset gas fires as this will be the only source of heat in the living room.
Thank you
