Enerstat thermostats are programmable and can be much more cost effective than a non-programmable device. They allow homeowners to set and schedule heating and cooling patterns in different areas of the home for when rooms are not occupied to use energy more efficiently.
As of 2015, the cost of installing an Enerstat thermostat ranges from $50 to $200, depending on whether or not the homeowner uses an electrician. Once installed, homeowners can use energy more efficiently by setting the thermostat to automatically adjust the home's temperature to coincide with use patterns. Certain Enerstat thermostat models can be controlled remotely over the Internet while homeowners are away from the home.
