<p>Water is supplied to a water user outlet facility (41, 42, 43) by maintaining a tappable flow of water in a recirculating loop that includes a pump (20) for establishing and maintaining the flow while imparting thermal energy to water, a water delivery path that extends from the pump to the outlet facility, a water return path that extends from the outlet facility back to the pump, and one or more water treatment devices (30, 31) for improving the potability of and imparting further thermal energy to water within said loop. The flow is permitted to be controllably tapped at the facility by a water user while directing any untapped portion of the flow into the water return path. Such recirculation makes the recirculating loop and water within the loop less sensitive to the temperature of the surrounding environment and enables water distribution in freezing temperatures without a need for external heating.</p> |
