UNDER-FLOOR HEAT-STORAGE TYPE HEATING-SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an under-floor heat-storage type heating-system capable of supplying such calorific value as considers heat radiation from a mat-foundation lower part and from a rising part of the foundation.

SOLUTION: A hot-water pipe 21 is laid in a floor concrete 13 of a house 1. A thermal medium is circulated to the hot-water pipe 21 from a heat pump unit 22 which is a heat source, to cause the floor concrete 13 to accumulate heat, so that the indoor of the house 1 is heated. Here, the hot-water pipe 21 is laid in such a manner that its height from the lower surface of the floor concrete 13 is within the range of 0.3-0.5 relative to the thickness of the floor concrete 13, with a buried volume being 0.30-0.40% of the volume of the floor concrete 13.
