Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heating system using remaining heat of remaining hot water in a bath, and a bath tub, capable of recovering and utilizing efficiently the remaining heat at low cost, by simple structure. SOLUTION: The bath tub 2 of the bath is formed into double structure comprising an inner tub 3 and an outer tub 4. An insulating layer 6 is provided in the outer tub 4, and a hollow part 5 formed between the inner tub 3 and the outer tub 4 is communicated with a ventilation space provided in a floor or the like in a house, via an air intake port 7 and an air take out port 8. Air in the hollow part 5 is made to flow through a space formed with respect to the ventilation space via a fan 10, while elevating a temperature of the air by the remaining heat of the remaining hot water 7 in the bath tub 2.
