Water heating accounts for 15-20% of all energy use in homes with electric water heating. Water-saving devices, such as thermostatic shut-off valves, reduce the energy required to heat water as less water is consumed. BPA supports water heating by offering heat pump water heater and thermostatic shut-off valve measures. 

Several water heating measures are also available to income-qualified residents at a higher incentive, with additional coverage for related repair costs. Reference BPA's Low-Income Energy Efficiency page for more information.
