What is the ignition temperature of a hot surface igniter?

The ignition temperature of a hot surface igniter is indeed around 1,200 to 2,200 degrees Fahrenheit, making an ignition temperature of 2,400 degrees Fahrenheit a common reference point in some contexts. Hot surface igniters are used in gas appliances, such as furnaces and water heaters; they work by glowing red hot when electricity is applied, enabling them to ignite the gas.

Understanding the temperature range is critical for technicians and safety professionals, as it informs the safe design, installation, and operation of appliances using hot surface ignition. At these high temperatures, it is essential to ensure proper material selection and safety measures to prevent fire hazards. The choice of 2,400 degrees as an ignition temperature provides a benchmark for evaluating igniters and their function within an appliance's ignition system.
