The best temperature for heating a house is typically around 68°F (20°C) for comfort and energy efficiency during the winter months.
Struggling to balance warmth and energy bills? You’re not alone. Many homeowners face skyrocketing heating costs while still feeling chilly indoors. Finding the perfect thermostat setting can feel like a guessing game—too high, and you waste money; too low, and comfort suffers.
The right heating temperature can improve comfort, reduce energy waste, and lower utility bills. In this guide, we’ll cover the ideal thermostat settings, factors affecting warmth, and expert tips for efficiency. For more ways to optimize home heating, check our energy-saving guide.
Key Takeaways
- 20-22°C (68-72°F) is the best daytime temperature for most homes.
- Lowering the thermostat by 7-10°F (4-6°C) at night or when away saves energy.
- Proper insulation and thermostat placement impact efficiency.
- Smart thermostats can automate temperature adjustments for maximum savings.
Ideal Heating Temperature for Comfort & Efficiency
The best heating temperature for a house is typically 20-22°C (68-72°F). This range keeps most people comfortable while preventing excessive energy use. The U.S. Department of Energy recommends 68°F (20°C) when awake and lower when sleeping or away. However, personal preferences, home insulation, and climate play a role.
According to HVAC experts, setting the thermostat above 72°F (22°C) forces your system to work harder, increasing costs by 3-5% per degree. Conversely, temperatures below 64°F (18°C) may lead to discomfort and potential health risks, especially for seniors or infants.
Optimal Temperature Settings by Scenario
| Scenario | Recommended Temp |
|---|---|
| Daytime (Home & Active) | 68-72°F (20-22°C) |
| Nighttime (Sleeping) | 62-66°F (16-19°C) |
| Away for Work | 60-65°F (15-18°C) |
| Vacation (Winter) | 55-60°F (13-15°C) |
Factors Affecting the Best Heating Temperature
1. Home Insulation & Drafts
Poor insulation increases heat loss, requiring higher thermostat settings. The U.S. Department of Energy states that sealing leaks and adding attic insulation can reduce heating costs by 15%.
2. Thermostat Placement
Avoid placing thermostats near:
- Windows or exterior doors (drafts skew readings)
- Kitchens (appliance heat causes false triggers)
- Direct sunlight (overestimates room temperature)
3. Household Needs
Elderly residents or infants may need slightly warmer settings (70-73°F / 21-23°C). Meanwhile, active adults or those wearing layered clothing can opt for cooler temps.
How to Save Money on Heating
Lowering your thermostat by 7-10°F (4-6°C) for 8 hours daily can cut heating bills by 10% annually (ENERGY STAR). Smart thermostats like Nest or Ecobee automate these adjustments.
Additional Tips:
- Use programmable thermostats to schedule temperature drops.
- Close curtains at night to retain heat.
- Service your furnace annually for peak efficiency.
FAQ Section
Is 72°F too high for heating?
While 72°F (22°C) is comfortable, it may increase energy costs. Consider lowering to 68°F (20°C) when possible.
What’s the cheapest temperature to keep your house?
60-65°F (15-18°C) when away or asleep balances savings and pipe safety.
Does turning heat down at night save money?
Yes! Reducing heat by 7-10°F (4-6°C) overnight can save up to 10% on bills.
Final Thoughts
Finding the best heating temperature involves balancing comfort, health, and efficiency. Start with 68°F (20°C) when home, lower it when away, and invest in insulation or a smart thermostat for long-term savings. Small adjustments lead to big rewards.
