Building parts and building systems are changed with the times. But records of development and changes of details are not almost handed down. Those records of change will be helpful to produce better development. In this study, we took notice floor heating systems, and surveyed connection between researches on patent and literature about those changes. As a result, the floor heating systems have importance to the improvement in floor of building parts, panels and dry building systems, and requirements of related to the manufacture/construction and the heat.
