To calculate the simple payback associated with the water savings from retrofitting
or replacing an existing steam kettle, consider the equipment and installation cost of
the retrofit or replacement, the water savings as calculated in Equation 4-8, and the
facility-specific cost of water and wastewater.
By switching to a self-contained steam kettle or by returning condensate back to the
boiler in a boiler-based system, facilities can also save a significant amount of energy.
This energy savings will further reduce the payback period and increase replacement
