ABSTRACT:
A method for introducing pure hot-spring water directly transported from a spa into baths of a spa house and for maintaining the purity and the freshness of the introduced water. Pure hot-spring water directly transported from a spa by a transportation means is supplied into an underground reservoir. The supplied water is pumped by means of a primary pump, then warmed to a certain temperature by means of a first heat exchanger utilizing warm circulating water warmed by a boiler. The warmed hot-spring water is stored in a storage tank. When the water level in a hot-spring water bath has lowered, hot-spring water is pumped from the storage tank into the bath by means of a secondary pump. When the hot-spring water in the bath is contaminated, the hot-spring water is circulated in such a manner that the water is first passed through a filter for hot-spring water to have the contamination contained therein removed, then returned to the bath. The water being circulated is warmed by a second heat exchanger utilizing warm water when, during the circulation, the temperature of the water has decreased.
