PROBLEM TO BE SOLVED: To provide a snow melting device capable of being easily installed on a roof and reducing the running cost. SOLUTION: This snow melting device melts the snow by sending the hot air to a snow melting device from an air sucking and exhausting device by collecting electric heat, earth heat, solar heat, exhaust heat of stove/boiler, and exhaust heat from a dwelling house of high air-tightness. A heating wire is inserted into a tube and the like and the snow is melted by the heat. As the device can be easily installed without damaging the roof, and installed with the combination suitable for a site by performing the examination at the site, the running cost can be reduced. By installing this device, the snow removing work from the roof becomes unnecessary. COPYRIGHT: (C)2004,JPO&NCIPI
