The ultimate in modern gas fire technology. A flueless gas fire uses a catalytic converter to convert harmful Carbon Monoxide into harmless Carbon Dioxide and Water Vapour. In return you get a much greater efficiency as there's no need to expel fumes, and therefore heat out of the room. This means 100% of the fuel produced can go out into the room.
With the increase in domestic fuel prices there is no better time to upgrade your fire to the most efficient option available.
