Koleda Solus Heat Boosted by Graphene

Koleda Solus Heat Boosted by Graphene
The graphene-based Solus radiator promises to cut heating costs by up to 95 percent.

The Solus radiator from Koleda is equipped with the team’s patent-pending nanotech coating and graphene-based heating element, which work together to offer both convection heating as well as infrared heating. This allows the unit to heat 50 square feet with up to twenty times less power. The Solus is also portable, weighing under ten pounds and standing with a slim, sleek profile, and can be preset to the desired temperature.

All electric resistance heaters are 100% efficient (radiant or oil or whatever; no matter) - all the input electrical energy is converted to heat. How could these guys possibly claim more efficient heating? Sounds very much like red herring. Koleda's unit input power is 200Wt - did you feel very warm when an incandescent 200 Wt bulb was on in your room as the only source of heat (and the visible light also converted to heat once it struck you/wall/etc.)?

But it has nanotech and graphene ;-)

The invention does not make sense unless the laws of thermodynamics are violated.
Resistive heating elements convert all the input energy to heat. Yes, one can have directional heating with proper reflectors. Their rendering shows a rectangular source, which does not seem directional. Why is it only 95% efficient? Resistive heaters are 100% efficient. Furthermore what is the use of graphene, especially when you need a resistor to transform the input into heat. The low resistance of graphene does not promote heating. This appears to be a vial of snake oil.
