The Peppermill Resort Spa Casino in Reno, Nev., features 1,635 luxurious rooms and suites, two Tuscan-inspired pools, nine award-winning restaurants, sixteen themed bars and lounges, free nightly entertainment, 24/7 gaming action and a 43,000-square-foot Spa and Fitness Center with an indoor pool, sun deck and a Secret Garden.
Since 2007, the Peppermill has used geothermal energy to heat water for its spa and fitness center, as well as its two outdoor swimming pools. The company has recently announced the completion of a $9.7 million addition to the geothermal system, which now allows the resort to heat 100 percent of its 2.1 million-square-foot facility’s domestic water – water used for things like laundry, bathing, dishwashing and cooking – and mechanical heat with geothermal energy. This ambitious project makes the Peppermill the only resort in the United States to meet its entire heating load with geothermal energy produced on the property.
For the HVAC addition, the Peppermill consulted with geothermal expert Jim Combs of Geo Hills Associates of Reno. Combs recommended that a second geothermal well be drilled on the property. The 4,400-foot-deep well is capable of pumping 1,500 gallons of 170-degree water per minute at 150 psi through a closed-loop system and back into the existing reinjection well on the property.
In addition to reducing the facility’s natural gas use, Peppermill executives estimate that the system upgrade will save the company millions of dollars over its lifespan.
