Electric thermal storage (ETS) heaters: What they are and what they do
ETS is a heating technology designed to store electric heat during the off-peak hours of the day when electricity costs are cheaper, saving you money. A super-insulated storage cavity containing ceramic bricks is charged (heated) to approximately 1,400°F and is stored for use during the on-peak hours of the day when electricity costs are higher. A fan forces air over the heated bricks sending the warm air into the room throughout the day; keeping you at a comfortable temperature while using a minimal amount of electricity. The ETS unit’s surface temperature is also safe for children to be near as it does not harm or burn when touched. When a member chooses to install an ETS unit they become eligible for a special time-of-use rate class, which allows the ETS unit to charge during off-peak times, when electricity is cheaper, and discharge the stored heat during peak times, when electricity is more expensive.
