When members put a Steffes Electronic Thermal Storage (ETS) unit on Polk-Burnett's off-peak program, it provides a very economical and safe heating source.

How it works:  Energy is stored in high-density ceramic bricks for eight hours overnight and two hours during the day when electricity costs are lower.  On today's newer models, this is done with an outside transceiver, which automatically tells the storage heater how much to charge based on the overnight outdoor temperatures.  This helps assure that you will have plenty of heat to use the next day.
