The solar hot water system provides water to comfort stations at a consistent temperature of 105°F. Tanks store hot water for each of the stations: 500 gallons for the small stations and 1,000 gallons for the large stations. Water demand is reduced by the use of low-flow showerheads and 1-minute push-button timers.
