Open fronted gas appliances can give a room all the warmth and atmosphere of a real flame fire - without the hassle!
When selecting a secondary heating appliance under the new Document L it is important to evaluate the carbon output of the appliance.
You can do this by examining a combination of
The graph below illustrates the combined effect of the fuel, and the appliance efficiency in carbon saving when compated to an electric fire.

Inset living flame effect gas fires (ILFE) offer efficiencies high enough to produce a carbon credit against an electric fire, and are available in two sizes — deep bed and shallow or narrow bed.
The deep bed decorative gas fire (DGF) has a low efficiency of around 20%, and on its own is not enough to produce a carbon credit against an electric fire. However, combined with an efficient flue box, it can. The efficiency of the combined unit has been certified at 45%, and when used in conjunction with a typical 90% primary heating boiler it can give a carbon credit against an electric fire.
The benefit of deep bed fires is that they can create the more authentic impression of an open fire. The DGF does this beautifully with its larger fire viewing area.
