摘要

PROBLEM TO BE SOLVED: To provide an inexpensive and efficient heating system by effectively using an underfloor space of a building having a mat foundation. SOLUTION: An air conditioner A is arranged in a first floor, preferably a space under a staircase 10 of the building wherein the mat foundation 5 is composed of a foundation slab 5a, and footing beams 5b and 5c. A hot air supply opening A1 of the air conditioner is communicated with one of a plurality of underfloor spaces 11 and 15 surrounded by the footing beams 5b and 5c. The plurality of underfloor spaces 11 and 15 are communicated with each other via a communication hole 8 formed in a footing beam 5c upper rim. The underfloor spaces 11 and 15 are communicated with an indoor space of the building through a gap in a floor material 12 or a wall material. An architectural heat insulating material 4, preferably polystyrene foam or the like is adhered to a top face of the foundation slab 5a and side faces of the footing beams 5b and 5c.
