What is Electric Thermal Storage Heat?

5100

OFF-PEAK ELECTRIC HEAT, also known as ELECTRIC THERMAL STORAGE HEATING (or ETS, for short) uses electricity purchased at night at discounted prices to heat bricks housed in insulated chambers within a specially designed ETS furnace, boiler or space heater, delivering the heat stored in the bricks to the heated space 24-7 using your existing distribution system and recharging itself again each night at the discounted price. Because an ETS heating system uses electricity at night when Concord Light has contracted for a steeply discounted rate, the utility is able to pass a significant savings on to you.

... is the most knowledgeable and experienced technician for Electric Thermal Storage Heating Systems in Massachusetts…experienced in repairing most major European and domestic brands: Steffes, Stiebel Eltron, & Technotherm. If you have an older European brand of ETS in your home, you may want to consider upgrading it to a modern computer-controlled ETS system from Steffes before undergoing the very expensive option of changing distribution systems entirely.
