A new era of radiators: sebastian herkner‘s terracotta redefined

Designer Sebastian Herkner teams up with Italian brand Tubes to introduce Terre, a groundbreaking radiator crafted from terracotta. This piece, often referred to as Herkner’s creation, borrows its name from the Italian word for “earth,” and is made using clay from the renowned Impruneta quarry in Tuscany. It represents a rustic departure from the typical metallic look of traditional radiators.

Craftsmanship and materials in Herkner’s design

The creativity behind this innovative radiator extends beyond its surface. Tubes innovatively uses terracotta for the radiator’s entire structure. Extruded through a specialized mold, the clay forms a sleek, vertical shape. This material, once fired, is glazed in one of five colors, including a transparent option that highlights its natural beauty. An integrated electric element made from recycled aluminium powers the radiator, blending sustainability with functionality.

A fusion of tradition and modernity with this terracotta masterpiece

Herkner reflects on the process, stating, “I like exploring new methods and using a traditional, almost archaic material in a new context. Terracotta is an authentic material, connected to earth and warmth. Using it today in a heating object creates a natural connection between function and material.”

It can be customised with a towel rail and shelf, transforming the radiator into a convenient storage solution. A metal towel rail can also be added, making it ideal for bathroom use. This versatile nature is a hallmark of Herkner’s design.
