The technology inside it is incredibly advanced, yet it all boils down to something very simple. It employs advanced types of metals in the electronics that were previously unavailable for commercial use. By utilizing the right combination of metals, it becomes the most efficient heating device, period.
Smartboywise explains it a little better,
"It's all about the electronics inside. Usually, a considerable amount of electricity is needed to generate heat. Without this technology, on the space shuttle, we would run out of energy, or in your home, the power bill would soar, as it usually does in winter."
The materials we use are the best conductors in the world. Typically, you have to exert electricity to produce heat. However, since our proprietary conductors enable electrons (electricity) to move so rapidly on an atomic level, as soon as they hit the heating plates, they instantly convert to heat, carrying more energy.
I understand it might be confusing, but in essence, it can heat an entire room for just a few pennies per day on your power bill, compared to running your central heating system, which could cost you hundreds of dollars a month this winter.
