Given the following:
Water Volume: 15,000 gallons
Water Starting Temperature: 75 F
Heating System: 420 GPH
Active Heating Hours Per Day: 8
Which of the following methods would raise the temperature of the water the most in 8 hours?
A) Heating system running constantly: In 8 hours, this method would introduce 3,360 gallons at a 4 degree increase.
B) 15 minute interval: Heating system on for 15 minutes, off for 15 minutes. The water coming out of the heating system after 15 minutes is about 120 degrees. It takes 1 minute to move 7 gallons of water at 120 degrees, followed by 14 minutes of water at 4 degrees warmer than it entered the system at. Then the system would turn off for 15 minutes. In 8 hours, this method would introduce 112 gallons at 120 degrees, and 1,568 gallons at a 4 degree increase.
