How to cut the cost
- Run it on high for 30 minutes before bed, then switch to setting 2-3 or off.
- Use the dual control so each side heats only as needed; an unused side should be off.
- Drop the thermostat to 60-62°F at night; the pad keeps you warm while the house cools.
- Choose a model with a 10-hour auto-off and unplug the controller in summer.
