Abstract
A catalytic heater 10 has an insulation pad 36 and a catalyst pad 34 mounted in face-to-face relation within an enclosure 11 having an open front face 20. A starter 48 is mounted within the catalyst pad and is effective for preheating of the catalyst pad. Fuel gas is supplied to the rear face of the insulation pad and air is supplied to the front face of the catalyst pad, so that a catalytic reaction occurs generally when the catalyst pad and sear the ope front face. After the catalytic reaction begins, electrical energy is ceased to the starter. The starter preferably comprises a quartz-halogen lamp of a relatively small size which is mounted within the catalyst pad.
