Should anything be specified differently when ordering a booster to be 
used in a low temp application?
The order should specify that the booster is for a low temp application and the factory 
will preset the thermostat to 140°F (60°C). There is a low temp sizing chart in the Hatco 
price list or on the website to verify sizing.
What is the function of the low water cut-off?
The low water cut-off (LWCO) is a protective device designed to shut off power to the 
heating elements,thus preventing burnout should the water level decrease in the booster tank. The LWCO is 
automatically reset when the water level is safe.
How is a booster heater to be positioned when installed?
The booster heater must be installed in a horizontal position, with the base parallel to the floor and the inlet
connection at the lowest point. The booster heater must be as close as possible to the dishmachine.
Are there any special provisions for booster heaters ordered for marine 
applications?
Boosters are available with 400 Series stainless steel body and base (resists rusting  
from salt air), with stainless steel flanged legs for deck mounting.
Why order an Imperial vs. Compact?
•  Step loaded element design can reduce energy costs (above 24kW).
•  Larger tank provides greater capacity and faster recovery.
•  Easier to service larger unit.
What is step loading?
Imperial Electric Booster Heaters (“S” series) rated for 24kW or larger have multiple banks 
of heating elements, with each bank controlled by a separate thermostat. During periods 
of use, the lowest bank of heating elements turns on first and stays on until its thermostat 
reaches the setpoint. If additional hot water is needed (during periods of high demand), 
the next level of heating elements come on and heats. This step loading, or staging of the 
heating elements, allows for reduced energy costs when compared to units that have all 
of their elements controlled by one thermostat and are either ON or OFF 100% of the time.
When should Gas vs. Electric be considered?
Use the energy cost worksheet on our website to calculate energy costs per year, and 
compare to unit cost. Consider installation and maintenance costs. (Contact your local Hatco Representative 
for assistance.)
