Radiator in which aesthetics, design and planning come together in a unique product with a perfect geometric shape. Donut is the heated towel rail which makes its main “ingredients” simple and clean. Made of high-strength steel, Donut consists of an outer circle with an important section and a smaller interior one. The two round valves complete the look for the hydraulic version, while in the electric model there is the special Hoop cable winding system.
