<p>PURPOSE:To reduce the running cost by storing waste hot water of a bath room in a hot water storage tank and reutilizing waste hot water stored as heat source water of a heat pump. CONSTITUTION:Spring water 10 discharged from a pump 11 is supplied to a condenser 12 of the heat pump and a heat source water tank 13 concurrently used as a purifying tank (a heating insulating tank). Spring water which has been supplied to the condenser 12 is heated by the operation of the heat pump and supplied to a hot water storage tank 14. Waste hot water 18 from a bathtub 16 and a hot water tank 15 outside the bathtub is guided from an underground pipeline to the heat source water tank 13 concurrently used as a purifying tank via a drainage groove of a washing place of the bath room and the tank 13 is burried underground and is hermetically bonded with a heat insulating material. Spring water discharged from a pump 20 is cleaned in the tank 13 with warm water of about 35 deg.C mixed with waste hot water 18 from the spring and the bathtub, and is supplied to a heat pump evaporator 21 as clean warm water. After radiating within the evaporator, the temperature of the heat source water is reduced to about 20 deg.C, and then the heat source water is discharged into river 22.</p> |
