Balanced flue gas fires
The next major change came at the beginning of the 21st century, with the production of continental-style balanced flue gas fires.
A balanced flue gas fire requires no chimney for installation, as it has an integral flue that can be inserted through an outside facing wall. The assembly is normally housed inside a false chimneybreast, with only the fire aperture visible.
Th advantages of this system are plentiful: the fire is not restricted in size by the chimney opening; many variations in size, shape and configuration can be designed; because it is room-sealed, with a glass front, it is more comfortable and energy efficient; and the flame picture that is produced is very realistic.
Since 2000, manufacturers such as DRU, Faber and an increasing number of British companies have produced balanced flue gas fires across the whole spectrum of sizes, materials, price points and efficiency standards. It is these gas fires that have become the appliances of choice all around Europe and the UK.
