I have been in the engineering business for 30 years. Specifically, plumbing. In the ASPE Data Book (pick any year), the hot water demand for showers in Gymnasiums, Industrial Plants, Schools and YMCA's has been declared 225 GPH. When will this number be corrected? IPC limits the flow for showers to 2.5 GPM at 80 PSI. 2.5 x 60 = 150 GPH.
Where did 225 come from? Who uses this number in their water heater calculations?
