The Hot Start showerhead, available in January 2015 from Niagara Conservation as part of the Stealth System, is a temperature-controlled, EPA WaterSense-certified showerhead. It uses a full flow rate while the shower water heats up, but once the water reaches 95° F, the Hot Start reduces the flow to a trickle, saving users thousands of gallons of water per year and reducing utility bills. Users then hit the RESUME button to shower with the water at its full flow rate of 2.0 gpm.
