GPM
Estimated flow rate, of domestic cold wate
r, required to maintain an
approximate 115 F output temperature of domestic hot water.
(GPM - Gallons per Minute)
The chart belo
w, is a graphical representation of how the Hydro-Hot’s Domestic Hot
Water System theoretically performs under varying domestic cold water temperatures.
Because each Hydro-Hot has a performance tolerance, this graph should be used as a
general guideline and not as actual domestic hot water performance data.
Notes of interest:
When water is heated to.....
156 degrees - Hot water causes a third-degree burn in one secon
d
149 degrees - Hot water causes a third-degree burn in two seconds
133 degrees - Hot water causes a third-degree burn quickly
115-120 degrees - General purpose temperatures
107-109 degrees - Average "Hot-Tub" temperatures
105 degrees - Average "Shower" temperature
