Considered one of Illinois's best golf courses, the St. Charles Country Club is located 45 miles west of Chicago in St. Charles, IL. Established in 1924, the club currently has 265 members and employs from 50 to 125 people, depending on the season. In 1987, the club added a 34,000-sq-ft clubhouse to accompany the 18-hole golf course.
By 2002, the facility's boiler system was in dire straits. At the time, the club was using two 455,000 Btuh high-efficiency heaters with a 1,500-gal storage tank to supply hot water to the club's 41 fixtures. The primary boiler had been replaced but with the storage tank leaking, the entire system needed an overhaul. Cook, whose job it is to keep the club running smoothly, considered three options for replacing the aging system: replace the boiler system with an identical one; install a system of multiple smaller tanks; or install a Takagi tankless water heater system.
