The sauna heater is at the heart of any sauna system. This is why Concept R – “R” stands for rounded edges – can be viewed from four sides, so that the sauna heater can be placed anywhere in the room. Its inner workings are also unusual. The three-casing technology used and the optional wooden railing offer maximum protection against accidental contact and burns. A removable junction box and electronic cover protection to avoid sauna fires complete the technology package.
