Selection:
Boiler: W1 - _______
Tank: _______ gallons
Sizing:
1. Calculate the hot water demand:
Number of machines x gallons per
load x number of cycles per hour
= GPH required.
2. Enter chart at Temperature
Rise find the GPH closest to,
but not less than, GPH
calculated.
3. Select the water heater, tank and
circulator recommended.
