Sebastian Herkner and Tubes Launch Terre, a Terracotta Radiator from Impruneta Clay

architecture-design · 2026-09-16

Sebastian Herkner, a designer from Germany, has collaborated with the Italian heating company Tubes to introduce Terre, their inaugural radiator crafted from terracotta. The name derives from the Italian term for "earth," and the clay is sourced from Tuscany's Impruneta quarry. Unlike standard metal radiators, Terre utilizes terracotta as both the structural body and surface finish, shaped through a unique extrusion process into a sleek, vertical design. Available in five glossy colors—Transparent Glazed Terracotta, Vitreous White, Bark Brown, Mineral Grey, and Ocean Blue—the transparent variant showcases the material's inherent qualities. An integrated electric heating element made from recycled aluminum provides warmth. Measuring 1120 x 140 x 1400 millimeters, it can be accessorized with a marble or lacquered shelf, serving as a multifunctional piece or a towel warmer. Herkner remarked on the innovative use of terracotta, emphasizing its authentic connection to earth and warmth. The Terre radiator is currently available via Tubes and was highlighted in Dezeen Showroom.
