To save energy, set your heater to 68°F (20°C) during the day and lower it at night or when you’re away, using a programmable thermostat for efficiency.
Heating accounts for nearly 42% of home energy use, but simple thermostat adjustments can yield significant savings. This guide reveals expert strategies to optimize your heater settings while maintaining comfort.
The 68°F Rule for Maximum Savings
The U.S. Department of Energy recommends 68°F as the ideal daytime winter temperature. For every degree you lower your thermostat below this:
- Save 1-3% on heating costs
- Reduce carbon emissions by 300-500 lbs annually
- Extend HVAC system lifespan by reducing runtime
Nighttime and Away Settings
Program your thermostat to:
| Situation | Recommended Temp | Duration |
|---|---|---|
| Sleeping | 62-65°F | 6-8 hours |
| Workday | 60-62°F | 8+ hours |
| Vacation | 55°F | Extended periods |
Choosing the Right Thermostat
Programmable vs Smart Thermostats
While basic programmable models like the Mr. Heater thermostat work well, smart thermostats offer advanced features:
- Learning algorithms that adapt to your schedule
- Remote control via smartphone apps
- Energy usage reports and savings tracking
- Geofencing to adjust when you leave/return
According to Energy.gov, proper use of programmable thermostats can save homeowners about $180 annually.
Special Considerations for Different Systems
Heat Pumps
Unlike conventional systems, heat pumps become less efficient when set back more than 2°F. Consider a specialized thermostat designed for heat pump operation.
Radiant Floor Heating
These systems respond slowly. Begin temperature setbacks 2-3 hours before needed changes to account for thermal mass.
Electric Baseboard Heaters
Require line-voltage thermostats. Look for models with adaptive recovery to gradually warm spaces before your wake time.
Advanced Energy-Saving Techniques
Zoned Heating
Install multiple thermostats to control different areas independently. Focus heat only where needed.
Thermal Curtains
Quality window treatments can reduce heat loss by 25%, allowing lower thermostat settings.
Smart Vents
Automatically close vents in unused rooms to direct heat where it’s needed most.
Myth Busting: Common Misconceptions
Myth: Turning heat way up warms the house faster.
Truth: Heating systems work at one speed – cranking the thermostat wastes energy.
Myth: Maintaining one temperature is most efficient.
Truth: Strategic setbacks save energy as shown in DOE studies.
Myth: Smart thermostats don’t work with old systems.
Truth: Most modern smart thermostats are compatible with systems dating back decades.
Seasonal Adjustment Strategies
Winter Optimization
- Use sunlight – open south-facing window coverings during day
- Reverse ceiling fans to circulate warm air downward
- Seal drafts around windows and doors
Summer Crossover
When switching to cooling mode:
- Start with 78°F as your baseline temperature
- Increase to 85°F when away for extended periods
- Use fans to feel 4°F cooler without lowering the thermostat
For homes with combined systems, consider the best through-the-wall AC/heater units for efficient year-round climate control.
