Abstract:
A space heater capable of providing both radiant and blown warm air heating to a space beneath the heater; the heater comprising a housing, the underside of which is recessed to define a channel in which a combustion tube is mounted; the heater having a burner communicating with a first end of the tube; and first fan means communicating with the combustion tube for moving combustion gases along the tube from the first end to a second end thereof; the housing having an aperture in an upper surface thereof, the aperture being linked to second fan means for directing air into the channel within the housing; and a heat exchanger plate mounted between the combustion tube and the aperture, the heat exchanger plate being shaped so as to surround an upper surface of the tube so as to absorb radiation therefrom and the prevent air from the aperture from impinging directly on the tube; whereby the air is heated by the heat exchanger plate before passing out downwardly through a lower end of the channel; wherein the space heater is of modular form and comprises a pair of end modules and one or more intermediate modules, the end modules and the intermediate modules being connectable together to form the heater; at least one of the end modules having said burner mounted, and at least one of said end modules having said first fan means mounted thereon; each said intermediate module comprising an intermediate portion of the housing having mounted therein an intermediate portion of the combustion tube and the heat exchanger plate, the intermediate portion of the housing having one or more apertures formed in an upper surface thereof, the apertures being linked to said second fan means for directing air into the channel within the housing.
