Electric Thermal Storage (ETS) is the technology of converting off-peak electricity to heat and storing this low cost heat for use in satisfying comfort requirements of a home or business 24 hours a day. An ETS system contains electric heating elements which lie within special, high-density ceramic bricks. These bricks are capabale of storing vast amounts of heat for extended periods of time. During hours a power company deems as off-peak, the elements generate the heat that will be stored in the bricks. This stored heat is used to satisfy immediate heating requirements and to provide total comfort during peak hours. Off-peak hours are the times of day or night when power companies usually have excess energy supply due to low demand. In commercial and industrial applications, it is those hours when "demand free" power is available and generally when consumption within the facility is low. On-peak hours are those times when a power company's demand for electricity and associated costs are high. For the commercial and industrial market, it is when their electric consumption is at its peak. Some power companies offer reduced rates or substantial discounts on electricity consumed during off-peak times. It is these reduced rates that allow ETS to provide considerable savings to consumers on their energy bills as compared to alternative heating options. Check with your local power company to find out if off-peak, time-of-day (or time-of-use), demand based, smart metering, or other preferential rates are available to you.
