In recent years, the fan heater utilized in industry and residence has become smaller, lighter, and more silent as the result of improvement. But, there is a problem that the noise is loud due to air pressure loss of heat exchangers. We developed fan heaters, the blades of which are made of ceramic heater, and warmed by Joule heat. We investigated relationship with flow and heat transfer in the casing, and the optimum shape of casing. In result, we found that it was more silent as the result of decreasing pressure loss.
