Space heaters

A space heater with a water boiler (22) and a cooker unit (31), comprising:

• a solid fuel combustion appliance including an upwardly elongated combustion chamber (10) having firebars (14) at its lower end, for supporting a fire bed (13);
• a first flue (18), for transferring heat to the water boiler (22), and a second flue (29), in parallel with and adjacent said first flue and said elongated combustion chamber for transferring heat to the cooker unit (31);
• said flues both having upstream ends positioned below said firebars;
• said combustion chamber communicating with the upstream end of said flues by transverse paths in an ash pit area (16) below said firebars, for the gaseous products of combustion, along which, in normal use of the space heater, the gaseous products of combustion flow from the combustion chamber downwardly through said fire bed to a position below said fire bars;
• first (27) and second (51) dampers operable to control the flow of the gaseous products of combustion through said first and second flues, respectively;
• said combustion chamber (10) comprising upwardly elongated hollow side walls (11) provided with an adjustable natural draft air inlet (25) and with a plurality of downwardly directed spaced air outlets (12) for discharging heated air downwardly and evenly into said combustion chamber above said fire bed (13) offset from said natural air draft inlet.
