6.8 HEAT EXCHANGER CLEANING
For hard water installations, AERCO high recommends use of its Scale Reducer system. The
Scale Reducer, model SR300, is strongly recommended for installations in areas with hard water
(>3.5 grains/gal, >59.9 mg/L). It provides an economical, maintenance free treatment of hard
water without the use of salt or any chemicals. The SR300 prevents new scale build-up and
eliminates existing build-up in water heaters, boilers and storage tanks, hot water piping, valves,
recirculation lines and pumps, mixing valves, showerheads and other plumbing fixtures. This
eliminates the associated heat exchanger overheating and lets the water heater continue to
perform at its peak efficiency (low-water heating cost). In addition to reduced inspection
frequency, the periodic maintenance to remove and flush the water heater for scale deposits is no
longer necessary.
Alternatively, AERCO recommends
that the heat exchanger of the unit be cleaned annually to
maintain maximum heat transfer efficiencies using a solution of HydroSkrub and water.
HydroSkrub is distributed by AERCO International, Inc. and is designed to dissolve the toughest
water scale, lime, mud and rust deposits from virtually any type of water-based equipment.
