Notes:
2) “Gallons” – The total volume of water drawn from the tank during this time.
4) All valves shown are approximate.
3) "Ind."- Draw may be made at this flow rate indefinitely with the outlet temperature falling less than 25
degrees from the outlet temperature at the beginning of the draw.
1) “Time (min.)” – The time water may be drawn from a fully recovered tank before the outlet temperature
falls 25 degrees.
