The Warm Springs Hospital Project completed a 1,500-foot well with pump and space heating system in 1979-1981. The well produced 174° F water, which was used for space heating at the facility. The heating system operated in 1983 with calculated yearly energy savings of approximately $77,000. The well and system is under review to determine the economics of redeveloping the well and space heating system.
