High Sierra Showerheads

Exterior view of Artemisia Cabin, a Net Zero Energy solar-powered Airbnb rental house in Washington State's Methow Valley.

Its two bathrooms feature High Sierra Showerheads' 1.5 gallons per minute (gpm) shower heads. Combined with a heat-pump hot water heater, these shower heads helped cut Artemisia Cabin's annual water heating energy use by an estimated 64%, compared with a home built to code-minimum standards.
