There are many different styles of fire on the market.  Everything from a fire that looks like a real coal fire to a hole in the wall with burning pebbles.

Different types of fires are grouped according to how they are flued.  

The most common type of fire needs to be installed to an open flue usually an existing chimney.

Decorative Fuel Effect (DFE)  - This type of fire looks like a real fire incorporating a burner, controls, coal bed and decorative wrought iron basket that fits into the base of an existing masonry chimney or existing period fireplace.  These fires generally require of permanent ventilation in the room unless the manufacturers instructions state otherwise.  These fire are usually very inefficient as the heat goes straight up the chimney as opposed to being convected back into the room.

Fires can be categorised further depending on whether or not they have a heat exchanger i.e. convectors.

Convector fires.   As air in the room is passed over a heat exchanger it warms and rises causing warm convected air currents to circulate in the room.  This is the most effective way to heat space. 

Radiant Convector - This is the most common type.  It has white radiant bricks and is sealed to the fireplace opening using the manufacturers original closure plate.  
Inset Live Fuel Effect
(ILFE) - This type of fire looks like a real fire.  It comes enclosed in a metal fire box incorporating a heat exchanger. The whole unit is inset into the chimney breast and sealed to the fireplace or surround.

There are fires available that do not require an existing chimney.  These will be flued directly through an outside wall.

Unit Heater
- This is a room sealed, balanced flue convector heater which must be fitted to an external wall.
Flueless Fire - are 100% efficient (no heat goes up a chimney).  This type of fire incorporates the latest catalytic technology whereby the carbon monoxide produced is converted to non-toxic carbon dioxide. No flue is required and this fire can be installed almost anywhere there is a natural gas supply.

Abacus Gas Engineers do not supply or install decorative fuel effect gas fires however, we are able to carry out inspections and certification i.e Homeowner Reports and Landlord Safety Certificates.

All gas appliances for use in the U.K. must carry a CE mark and manufacturers installation instructions must be on hand before the appliance can be installed.  There are many regulations regarding the installation of gas fires to existing fireplaces and chimney.
