water loop / product design

The usual procedures of taking a shower is to discharge the water, adjust the temperature and take the shower, which means that when people discharge the water and adjust the temperature, the earliest water that doesn’t reach the desired temperature is wasted. A switch with “water loop” design can set the desired temperature directly by turning the external ring. As a result, the usual shower-taking procedures are changed—water temperature is adjusted to reach proper level through an internal temperature adjustment mechanism before any water is released, so that waste of water is avoided, and water is utilized more efficiently.
