Central Storage Furnace

Heating Rate - 3.9¢/kWh

Central storage furnaces use electric thermal storage (ETS) technology that converts electricity to heat during low-cost off-peak hours and stores the heat in specially designed, high-density bricks, which provide enough heat from storage to heat your home or business during the 16-hour on-peak portion of the day.

  • Heat is distributed through forced air or hot water systems.
  • A sensor monitors the outdoor temperature to determine how much heat must be stored in the bricks to adequately heat your home.
  • The storage furnace offers an industry leading five-year warranty for both parts and services.
  • A central storage furnace can serve as your sole heating source, or can be used to supplement heat pump systems.

Plus, it’s safe and clean. No chimneys, no flues, no backdrafts. No carbon monoxide.
