    (54) Improvements relating to gas fires


    (57) The present specification discloses a gas fire incorporating a heat exchanger (1) for use in transferring heat from the gaseous products of combustion in the gas fire (9) to a path (15) through the fire (9) for convection air. In certain such gas fires the heat exchanger is of a complex and expensive construction.
    The present invention provides a gas fire (9) with a simple and inexpensive heat exchanger (1). A number of these heat exchangers (1) are provided, each being in the form of a hollow tubular element (1) made of a thermally conducting material. Each hollow tubular element (1) extends across a path (15) for convection air in the fire (9), and provides a passage therethrough for gaseous combustion products passing to a flue at the rear (19) of the fire (9). To aid heat transfer fins (5) can be provided on the outside of the hollow tubular element (1).
