The Seta radiator offers a bold design while operating as part of a closed loop water heating system. Designed to be variable, the system provides an efficient heating solution in almost any setting and integrates harmoniously into a modern ambience. The 5-centimeter steel tubes are concentric cylinders, which each form a water jacket. Air circulates up the insides and is forced through the pepper shaker tops. Seta is also available with a towel warmer feature.
