BPA offers measures for Thermostatic Shut-Off Valves (TSVs) and showerheads. More information, and a qualified product list (QPL) of approved products are below.
The Benefits of Energy Efficient Showerheads and TSVs
Energy-efficient showerheads save electricity by reducing the amount of water used and decreasing the amount of energy needed to heat the water. Energy-efficient showerheads have an output of 2.0 gallons per minute or less. Today's showerheads are efficient without compromising on comfort and come in a wide range of styles. Using an efficient showerhead works with the water heater, helping the existing supply of hot water last longer.
There are two main kinds of technology used in these showerheads: Aeration and flow restriction.
  • Aeration incorporates air into the stream of water, either by drawing air in or forcing it into the water stream with compressed air. This process allows the showerhead to maintain consistent pressure, velocity, and spray.
  • Showerheads that use flow restriction emit a pulsed stream of water, maintaining the water temperature throughout use and providing for a strong water flow.
  • Another type of energy-saving showerhead incorporates a shut-off valve feature that allows the shower to be turned off while either soaping or shaving. This feature saves even more by stopping the flow of heated water.
Thermostatic Shut-Off Valves (TSVs) are a device installed between the shower arm and showerhead fixture. The device places a hold on flow when the water reaches 95 degrees F (35C), reducing hot water waste while waiting for warm up. The reduced trickle continues until normal flow is intentionally restored through manipulation of the unit. TSVs are available both as a stand alone product, and as a combination unit with an efficient showerhead built in.
How BPA Supports Efficient Showerheads and TSVs
BPA provides regional coordination of the Simple Steps, Smart Savings™ promotion in collaboration with northwest public and investor-owned utilities. Simple Steps, Smart Savings™ is primarily a retail program, promoting efficient lighting and showerheads at the point of purchase through merchandising and incentives.
BPA also supports direct mail and direct install showerheads and thermostatic shut-off valves. Materials to support these delivery channels can be found on the Simple Steps, Smart Savings™ website.
Utilities should always refer to the most current BPA Implementation Manual for specifications, documentation requirements, and current BPA reimbursement levels.
Please note: BPA does not provide incentives directly to homeowners. Please contact your local utility for details.
