Abstract
A piping apparatus for melting snow and ice, wherein a large number of heat radiation pipes are arranged below or above a surface from which snow or ice is to be melted and removed. One of the ends of each of the heat radiation pipes is communicated with an inlet side header arranged in a direction substantially orthogonal to the heat radiation pipes, and the other end of the pipes being communicated with an outlet side header arranged in a direction substantially orthogonal to the heat radiation pipes, thereby constituting a piping arrangement unit. The inlet side is communicated with a feed supply of a heating medium such as hot water so as to pass the supplied heating medium such as hot water through the heat radiation pipes. Heat retaining members having therein a heat accumulation material are disposed between the heat radiation pipes, whenever necessary. The apparatus can heat uniformly and economically a space adjacent the surface from which the snow and ice must be melted and removed, over a wide area or a long distance.
