Electric Thermal Storage (ETS) heat is quiet, odorless, extremely comfortable, and very affordable, based on a concept of heating that originated in Europe.
The Benefits of ETS
No oil tanks or fuel deliveries to worry about
No wide price fluctuations that make budgeting difficult
No burners to maintain or fumes to vent
Quieter operation - practically no sound
Uses existing baseboard or air ducts
How does ETS work?
In an ETS system, a heating medium, composed of very dense ceramic bricks, is combined with electric heating elements running through this medium. The elements are turned on during off-peak hours when we can charge a lower rate. The bricks heat up and then store the heat for hours inside the insulated cabinet. During peak hours, we cut off the heating elements and your ETS unit heats your home by operating a small fan that circulates air over the bricks. This accompanying GIF demonstrates how the metal coils within an ETS furnace are used to heat its ceramic bricks, which store heat throughout the day until released into your home by an internal fan.
By shifting the energy use to off-peak hours, we help keep overall rates to our members low. ETS is also a greener way of heating your home, removing reliance on oil and reducing the amount of energy consumed during peak times when demand for energy is highest.
ETS units are available in room units, as a central furnace, and as hydronic units where water is heated and circulated through your floors and baseboard units.
All of our ETS installations come with installation of a second electric meter onto your home. This second meter strictly measures the electricity being used by the ETS heating unit(s), separately from the meter accounting for your home's usual electricity use. This arrangement allows us to control the hours in which the ETS units can be charged, leaving the rest of your electric service undisturbed.
