I don't have a chimney but i'd like a stove!..........no problem!
If you don't have a proper brick built chimney you can still have a real fire by using twin wall insulated flue. These are a stainless flue surrounded by insulation and finished with an outer skin of stainless.
A 6 inch flue usually has an outer diameter of around 8 inch and a 5 inch flue has an outer of around 7 inch. These flues come in a high shine, stainless steel finish and can be powder coated in any British Standard or RAL colour to match the colour of guttering or paintwork if necessary.
They can be placed through an external wall and up the outside of the house or they can run indoors through lower and upper ceilings. These can then be boxed in with a timber frame, plasterboarded and emulsioned/wallpapered or they can be incorporated into fitted wardrobes. We've also incorporated them into corner shelving and other such things in the past. They don't need to be unsightly and ugly.
Twin wall prefabricated chimneys can be placed within 50mm of combustible materials which enables simple routing of the flue throughout the house with minimal disruption. Very often no redecoration is required afterwards.
Twin wall flue are still quite warm to the touch so can be an effective way of heating upper rooms if grills are installed to the boxing-in.
