Abstract
A radiant gas heater includes one or more gas inlets 105, for receiving gas from a gas supply and one or more air inlets 110. The heater includes gas burners 120A-120E, in which the gas is burned using oxygen admitted through the air inlets 110. One or more heat emitting elements 125A-125E are included, which emit infrared radiation using energy generated by the gas burners. One or more ionization probes 130A are provided proximal to two or more of the heat emitting elements for detecting the presence or absence of a flame. A housing 115 accommodates the gas burners, the heat emitting elements and the ionization probes. One or more control units are provided which are in electrical communication with the ionization probes and the gas inlets, the control units operable to shut off the gas supply if the ionization probes detect the absence of a flame.
