As of February 2015, Duraflame heaters are powered by electricity. Certain Duraflame heater models use Powerheat Infrared Quartz heat. The quartz heating elements heat up two bent sheets of copper, which then raise the temperature of the air that passes through them.
Duraflame heaters that use Powerheat pass a room's air through an air filter to remove dust and dirt particles. A fan then blows the air through the heater, where it is heated by the sheets of copper. As the air is blown out of the heating chamber, it creates a soft, moist heat.
Infrared quartz technology creates a healthier heat than conventional heating systems because it keeps higher oxygen and moisture levels. Duraflame's Powerheat heaters are able to warm rooms up to 1,000 square feet. The quartz heating elements have a lifespan of at least 20,000 hours.
In addition to infrared heaters, Duraflame also manufactures desktop heaters, tower heaters, convection heaters, utility heaters, electric stoves and log sets. Duraflame heaters have an adjustable thermostat with a temperature readout that can be set to either Fahrenheit or Celsius. The heaters also have a timer function, and many include a tip-over safety switch that automatically shuts the machine off if it falls.
