What drives the difference
- Infrared heater: Infrared and quartz heaters use the same 1,500 W maximum as other plug-in heaters. Claims of 50% savings are not physically possible; savings only come from heating people directly instead of the whole room.
- Ceramic space heater: Ceramic heaters blow air over a PTC ceramic element and typically run 900 W on low and 1,500 W on high. They heat a small room quickly but stop warming it almost as soon as they cycle off.
Ways to cut either cost
