Elstein IRH infrared radiators are ceramic radiators in bi-convex design. The radiating surface consists of ten small longishradiation surfaces, which are also designed in a convex shape. Compared to IRH/S the radiating surface was enlargedby almost 60 %, which is more advantageous for the radiation distribution in the room. Additionally also aesthetical requirements in the wellness sector are fulfilled in a particular way. The thermally insulating inner space of IRH has a share in improving the radiator‘s efficiency. When connected to 230 V the Elstein IRH infrared radiators are available in wattages of 200 W and250 W.
