Hot Water Contest

(100 points)

The U.S. Department of Energy Solar Decathlon Hot Water Contest assesses whether a house's water heating system can supply all the hot water needed for daily washing and bathing. Teams score points by successfully completing several 15-gallon "hot water draws."

The goal of this task is to deliver 15 gallons (56.8 l) of hot water (110°F/43.3°C) in 10 minutes or less.
