Abstract: A gas fire has a fire bed shaped to receive simulated solid fuel. Gas burners direct flames onto the firebed through the simulated fuel and out through a heat exchanger. The fuel glows in an appealing manner.

Abstract: A gas fire comprises a fire bed made of refractory material with a plurality of holes therein, mounted within a combustion chamber so as to divide the combustion chamber into an upper and a lower portion, gas burners mounted so as to direct flames substantially across the upper surface of the fire bed, and a heat exchanger with a primary and secondary section, and respectively, to provide extended circulation of combustion products. Inlet of the heat exchanger is located at the rear wall of the lower portion of the combustion chamber, so that combustion products are drawn through the holes into the lower portion for entry into the heat exchanger. Simulated solid fuel elements are supported on a grid above the fire bed.
