Booster Heater Sizing Chart
Use the table below or the “Booster Heater Sizing Formula” to determine what Booster Heater kW rating is needed with your
dishmachine.
1. Determine the water temperature rise.
a. Subtract the lowest incoming water temperature supplied to the Booster Heater from the desired output water temperature
of the Booster Heater. The difference is the Water Temperature Rise. Typically 145°F (63°C) is a low temperature chemical
sanitizing application and 185°F (85°C) is a high temperature heated water sanitizing application.
2. Follow the appropriate “Water Temperature Rise” column down and locate the Gallons Per Hour (GPH) of the dishmachine’s rinse
cycle (round up to the next size if exact GPH isn’t listed).
NOTE: The primary water heater must be able to supply the Booster Heater with the incoming water temperature at the GPH usage
of the dishmachine. Failure of the primary water heater to supply a continuous temperature will result in an inadequate
output temperature of the Booster Heater.
3. Follow the GPH row to either of the “Booster Heater kW” columns for the appropriate Booster Heater kW rating.
Example: An incoming water temperature of 115°F (46°C) with a desired output temperature of 185°F (85°C) would be a 70°F
(39°C) water temperature rise.
A 70°F (39°C) water temperature rise with a dishmachine capable of 185 GPH usage will require a minimum of a 36 kW
Booster Heater.
NOTE: When incoming water temperatures are less than 85°F (29°C), consult factory for suitable Booster Heater.
