FYI: thermal-storage room units

Room-by-room control and comfort from a thermal-storage system.

What are thermal-storage room units?

Regulating heat at the room-level can now be handled through a thermal-storage option, allowing you to store heat when prices are lowest and use it when—and where—you need it.

Benefits of thermal-storage room units

Room units are ideal for retrofitting electric baseboard-heated homes, supplementing an existing system, or reaching a new addition or cold spot in your home. Thermal-storage room units are also:

  • Versatile — Can be added to new or existing buildings, home additions, or large institutions like schools, courthouses, or nursing homes
  • Clean — Dust-free consistent heating leading to a clean and quiet system
  • Zoned — Get room-by-room control over heat levels, eliminating hot and cold spots
  • Efficient — 100% energy efficiency and eligible for our discounted off-peak rates

How do they work?

Like all thermal-storage systems, you can think of this system as a kind of “heat battery” storing energy until it’s needed.

Unique and specially-designed, the ceramic bricks within the thermal-storage unit store heat during off-peak hours. Then, when it’s time to warm up, heat is transferred through the room.

The added benefit of this system is that it permits zoned heating and room-by-room temperature control.
