Not sure how much hot water you need? Learn More.Do you need to run 2 showers at the same time or maybe a shower and a dishwasher at the same time?  The chart below shows the amount of hot water and average water temperatures for various applications.  We suggest using 2.5 gallons per minute (gpm) for a shower in determining your total hot water needs.

Fixture	Average Flow GPM	Avg. Temp.
Tub	4.0	102 F
Shower	2.5 - 3	104 F
Body Jets/Sprays (each)	1.0-2.5	104F
