| Electric Thermal Storage Heating |
Efficient technology reduces your billing demand and your electricity bill!
If you're a business customer and pay a demand charge, a thermal storage heating system can make a big difference on your electricity bill. It can optimize heating costs for shopping centres, office buildings, schools, hospitals, arenas, churches, post offices, underground garages, sports and recreational centers, industrial plants and many other types of buildings. Your investment can generally be recovered within five years.

Electric thermal storage
|
Electric thermal storage (ETS) is an intelligent heating system that stores heat during low-consumption (off-peak) periods and discharges it when your power demand is high to reduce energy costs. When your power demand is low, electrical resistance elements heat high-density ceramic bricks to very high temperatures. The stored heat is circulated later by your heating system to provide heat without using additional power during costly peak periods. The storage module can output and store heat simultaneously, so your heating needs are covered at all times.
Effective Capacity
Electric thermal storage can shave substantial amounts off your load for several hours. For example, it can deliver the equivalent of an 80-kW furnace for 8 consecutive hours using only the heat from its thermal storage mass. This is equivalent to the power required to heat a dozen single-family homes for 8 hours when the outdoor temperature is –30°C! What’s more, several modules can be installed on the same system to increase heating capacity.
An Integrated Solution
Since ETS systems come with a built-in load management controller, they offer a turnkey solution for customers with no energy management system. In addition to automatic control of thermal storage based on power demand, the controller can manage 16 other electrical loads in the building.
With ETS, you can reduce your billing demand, optimize your consumption profile, and save on your electricity bill. It's a truly integrated solution that combines electric heating, heat storage and energy management.
Two versions are available:
- forced-air
- hot-water (hydronic)

- Can actually reduce billing demand, even though it's electric heating
- Improves your load factor
- Maintenance is minimal and easy (parts are readily available)
- Easily adapted to existing equipment
- Works with all water or forced-air systems regardless of flow capacity
- Much more compact than other systems
- Stable rates mean predictable heating costs
- Short payback period (usually less than five years)
- Less energy and power consumed during the most expensive times
- Controls peak loads–an important factor for customers paying a demand charge (rates G, G9, M, MR and L)
- Can also manage up to 16 other power loads in the building.

An ETS system can:
- preheat fresh air or act as a central heating unit without creating any peak demand
- provide an attractive solution for customers migrating from Rate BT to other rates for better control over their heating costs
- cost-effectively replace a gas or oil heating system (in terms of both purchase price and cost of operation and maintenance)
- optimize heating costs, whether the building or area is used only part of the day (schools, shopping centres and office buildings) or around-the-clock (hospitals)
- shave a daily demand peak caused by preheating cold air
- increase heating capacity in a building or group of buildings without having to expand the main electrical service, while reducing the average unit cost of energy
