A smart thermostat takes some of the guesswork out of managing your home’s energy use. It automatically adjusts heating and cooling settings based on your schedule to help keep your home comfortable without running your system more than necessary. According to energystar.gov, ENERGY STAR certified smart thermostats save an average of 8% on heating and cooling costs per year.
Many models learn your preferences over time and adjust automatically. Almost all use a mobile app so you can manage settings from your phone. That level of control can help reduce unnecessary energy use even when you’re away from home.
Plus, when you purchase a qualifying smart thermostat from the Alliant Energy® Marketplace, you can receive an instant discount and earn ongoing rewards by enrolling in Alliant Energy® Smart Hours. The Smart Hours program helps us coordinate with lots of smart devices across our service territory to help reduce spikes in energy demand on extra hot or cold days. During occasional Smart Hours events, your thermostat will make small adjustments to shift energy use away from times of high demand – all while maintaining your home comfort. You’ll receive an enrollment bonus, along with $25 for each season you participate.
