GET TO KNOW ELECTRIC THERMAL STORAGE

Electric thermal storage, or ETS, is an electric home heating device containing ceramic bricks that can help lower your heating costs by storing heat when electricity costs less and then releasing the heat throughout the day. Our Time-of-Day (TOD) rates are what makes an ETS cost-efficient. TOD rates change depending on the overall power demand. During off-peak times—overnight, on weekends, and holidays—the demand for power is lower, resulting in a lower billable rate. Find a preferred contractor to determine if ETS is the right solution for you.

Benefits

Save Money

Our time-of-day (TOD) rates are what makes an ETS cost-efficient. TOD rates change depending on the overall power demand. During off-peak times—overnight, on weekends, and holidays—the demand for power is lower resulting in a lower billable rate.

Save Energy

TOD rate savings apply to more than just your heating—it’s a “whole-home” rate. So, everything in your home that consumes power does it at a lower rate during off-peak times, from lighting to appliances. You’ll cut costs even more by using your washer, dryer, and dishwasher during the off-peak period.

Types of Electric Thermal Storage

There are three main types of ETS systems, though all function basically the same way—they store heat while power rates are discounted, and release the heat as needed.

This is the simplest to add to an existing home and any existing heating system. A standalone cabinet, you simply find a convenient place to locate it in your room, and have it hard-wired by an electrician. Cabinets vary in size, but they’re generally only about 10” to 12” deep, so they integrate well into most homes' décor.
Proper sizing is critical and all brands do not provide the same amount of heat storage. Ensure that the units are strategically placed throughout the home to provide maximum comfort and savings. If the units are undersized, other heating sources in your home need to turn on to maintain a comfortable temperature and this will offset potential savings.

This option replaces your existing furnace - this is an ideal solution when looking to cleaner home heating systems. These ETS systems come in both forced air and hydronic versions, so if your current home heat is distributed by forced air (through ductwork) or hot water (through radiators), there’s an ETS upgrade for you.

The big difference with in-floor radiant ETS systems is that rather than using ceramic bricks to store the heat, it uses the concrete slab of the floor itself. In this system, water is heated during off-peak hours, and pumped through the home’s concrete floor(s).

Did You Know?

Combine your ETS with a heat pump, save even more. Ask a preferred contractor if this combination is the right solution for your home.
