Get Comfortable with Low Cost Electricity! 

Steffes Electric Thermal Storage (ETS) heaters store heat during off-peak hours when electricity costs are at the lowest, then release the stored heat when it is required throughout the day. ETS is a proven electric heating system that works with many off-peak rate programs offered by Minnesota Utilities. It automatically delivers savings by storing the heat at night and taking advantage of the cheaper off-peak power rates. View our Steffes + Off-Peak Rates brochure.
