It's a radiator in the form of modern art. This cool design comes all the way from Germany, from a company called Sprinz. Sprinz has designed a radiator that uses slabs of glass to generate heat. As if that weren't cool enough, you can choose different themes for your radiator including a fireplace theme.
The Supratherm can be used as a free standing radiator or you can wall mount it to make it feel even more like fine modern art. Sprinz shows the Supratherm in many different uses, from the family room to the bathroom. If you can read German you can check out Sprinz website to see all of their designs.
