When the catalytic heater is turned on the catalyst is preheated with a tubular electric heating element for approximately 15 minutes. Once the catalyst has reached 300°F, safety devices are activated allowing gas to enter the back of the heater. The gas intermingles with the hot platinum catalyst and oxygen present in the surrounding air, starting an oxidation reduction reaction. This raises the catalyst temperature to between 350°F and 900°F, at the same time releasing water vapor and carbon dioxide. Efficiency tests have established that up to 80% of the gas is converted into infrared heat. Since the reaction temperature is well below the auto-ignition temperature for natural gas (1300°F), the reaction is flameless. The catalytic reaction is fully established five minutes after the gas enters the heater, and the pre heater is turned off.
