Function and mode of operation The RBH Electric Fan Heater operates on the principle and mode of operation of a central heating system. In contrast to central heating, where the radiator heats up with warm water, the RBH electric roof heating system heats the multitude of sheet steel heating ribs with the large-area genuine pure fireclay storage core. The heat generated in the interior of the fireclay by airtight embedded heating resistors, migrates by means of heat conduction to the outside. It is, as long as the stone is not heated, partially stored as heat and partially released from the outside of the stone. When the stone is heated, the heat storage ends and from that moment on, the heat generated inside is completely released from the outside. The fireplace-like ribs are made of high-quality steel welded at intervals of only one centimeter from both sides on the housing. As a result, a much enlarged surface is achieved. Since the fireclay bricks rest on the entire heating surface from the inside, the heat distribution over the entire surface of the radiator is uniform. As a result, an intense and pleasant heat radiation is achieved. In addition, the chimney-like ribs also produce good natural convection. The optimal combination of radiant heat and convection gives the RBH heater an optimal efficiency in its overall performance. The RBH heater is not only characterized by quality and performance but also your outer dress is modern and timeless. Their line in shape and design is captivating. It harmoniously adapts to every style of living. The white electrostatic powder coating (RAL 9001) is baked at over 200 degrees and is scratch-resistant as well as light-resistant.
