"The Janesville Pick ’n Save store, for instance, invested $11,700 to install controls on “anti-sweat heaters” so that the heaters—which prevent condensation from forming on refrigerated display cases—are used at full power only when necessary. Based on an electricity cost of six cents per kilowatt-hour (kWh), savings are projected at $15,900 a year. The upfront costs were a one-time expense. The savings will continue year after year."

"The controls are relatively inexpensive, easy to install and maintain, and are likely to pay for themselves in a year or less. A store with the equivalent of 36 four-door display cases is projected to save approximately $15,900 a year, based on an electricity cost of six cents per kilowatt-hour (kWh)."

Anti-Sweat Heater Controls

"Anti-sweat heater controls sense humidity conditions in the store and turn the heaters off when they are not needed. Anti-sweat heaters are electric heaters installed in virtually all low temperature — and many medium temperature — display cases to keep their external surfaces free of condensation during high humidity conditions. Typically, they are on all the time. Energy savings estimates range from about 6% for grocery store display cases to 14% for reach-in freezers, and 20% for reach-in refrigerators."
