HEAT CIRCULATION SYSTEM, BUILDING MATERIAL AND BUILDING

摘要

PROBLEM TO BE SOLVED: To provide a heat circulation system capable of reducing the capacity of a hot water storage tank that stores hot water generated by an energy generating apparatus.

SOLUTION: The heat circulation system includes a plurality of energy generating parts for generating hot water; hot-water piping for causing the hot water generated by the plurality of energy generating parts to flow therein; cold-water piping for causing cold water whose temperature is lower than that of the hot water flowing in the hot-water piping to flow therein; building steel members disposed along the longitudinal directions of the hot-water piping and the cold-water piping and adjacent to the hot-water piping and the cold-water piping for transferring heat from the hot water flowing in the hot-water piping to the cold water flowing in the cold-water piping, so as to lower the temperature of the hot water flowing in the hot-water piping while raising the temperature of the cold water flowing in the cold-water piping; and a hot/cold water draining part for draining the cold water flowing in the cold-water piping or the hot water flowing in the hot-water piping to the outside.
