I love radiators that don’t look as such. Crossing over the classic and limitative border of normal radiators is always a great design move.
Tubes Radiatori spawned Milano, a new generation of hydraulic radiators. Tubes Milao are made of steel but you can choose the color of the paint to match your interior so no one would notice their actual function. You can use the tubes either standing on their own because there’s a supportive base to them but you can also attach them to the walls for a great statuesque effect. I look forward to more radiator shapes that I could consider part of my interior rather than a functional piece only meant to heat the space. (via)
