<p><P>PROBLEM TO BE SOLVED: To achieve prefabrication around piping by providing a header device and a central piping device to simplify the piping of a multi-function water heater system. <P>SOLUTION: An underfloor structural drawing indicating an underfloor structure of a building is taken in an information processing device determining a piping route of the water supply system, the piping route is determined so that a functional header and a functional unit connected with the water heater system can be stored in one casing, the functional header and the function unit are incorporated in the housing on the basis of contents determined by the information processing device, members around the piping are prepared by adjusting lengths of piping materials, selecting joints, or the like, and they are assembled before being carried to a construction job site. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
