ShowerStart conveniently saves the water and energy used while waiting for the shower to become warm.

With ShowerStart, a small thermostatic shut-off valve (TSV) is all that’s needed to save the resources homeowners don’t even realize they’re wasting. Better still, conservation occurs without changing the shower’s feel or flow.

Because it saves the hot water that’s used during the shower warm-up process, rather than taking water away from homeowners while they’re showering, ShowerStart is an ideal solution for enhancing a homeowner’s comfort while improving the home’s sustainability.

ShowerStart, available exclusively in evolve brand showerheads and bathing fixtures are being adopted by home builders because of its comfort-oriented yet highly effective results. It’s also the only solution capable of cost-effectively combating shower-based behavioral waste.


  • Enhances Bathroom Appeal – conserves without impacting the shower’s flow or feel
  • Increases Homeowner Comfort – allows homeowners to prepare for their showers without worrying about hot water waste
  • Lowers Homeowner Utility Bills – saves water as well as the energy that’s used to heat it
  • Behavioral waste occurs when bathers use their time comfortably and efficiently while waiting for hot water to reach the shower.

    Instead of patiently waiting for cold water to exit the showerhead most people leave to do something else.

    Typical activities include brushing teeth, using the washroom and picking out clothes. Because bathing only begins after the tasks have been completed, countless gallons of hot water are unintentionally wasted at the start of every shower.


    The Home Energy Rating System (HERS) Index is the industry standard by which a home’s energy efficiency is measured. It’s also the nationally recognized system for inspecting and calculating a home’s energy performance.

    Traditionally the HERS Index has not considered hot water distribution systems and advanced hot water technologies within its calculations. However, home builders have expressed interest in additional opportunities to reduce energy use through smarter plumbing design and enhanced product choices.

    The Residential Energy Services Network (RESNET) is responding to these requests and is in the process of amending the HERS Index to include a class of products referred to as “Approved Hot Water Operational Control Devices” of which products with ShowerStart are apart.

    We anticipate approval for these devices and their inclusion within the calculation of a home’s HERS Index by early 2015.
