Specially-designed ceramic bricks help efficiently and economically store heat.
A central thermal-storage furnace uses specially designed ceramic bricks to store heat during off-peak hours, when electric rates are lowest.
Central thermal-storage furnaces can be combined with a heat pump—such as an air source heat pump or a cold-climate heat pump—to reach all-season comfort with an overall winter-season efficiency of 150% to 250%.
Central thermal-storage furnaces are clean and quiet. In addition:
Like all thermal-storage systems, you can think of a thermal-storage furnace as a kind of “heat battery.”
Unique and specially-designed, the ceramic bricks within a thermal-storage furnace store heat during off-peak hours. Then, when it’s time to warm up, heat is transferred through the building—either as heated air flowing through ductwork or through heated liquid flowing through floor heating.
Combining a central thermal-storage furnace with a cold-climate heat pump allows for a pairing of strengths—first, the heat pump operates at high efficiency to meet most of your heating and all of your cooling needs. Then the thermal-storage furnace is ready to provide the remainder of your heating needs during the coldest weather at 100% efficiency. Heat is stored throughout off-peak hours and available to provide comfort during the coldest weather.
