Other forms of electric heating, such as storage heaters, are inefficient because they have to be heated to a very high temperature in order to work well. Most also have to power fans to distribute heat around the room. Infrared panels have a thin, tightly-coiled heating element evenly distributed across the inside. They only need to heat themselves to the relatively low temperature of 90°C in order to work efficiently, and there are no fans. The temperature output is the same as other electric heaters with a fraction of the energy input.
