What Is the Best Temperature to Heat Your House?

The best temperature to heat your house for comfort and cost efficiency is between 68°F and 70°F during the day when you’re home and awake. Lowering the thermostat to between 60°F and 65°F when you’re asleep or away can save significant money on heating bills without making your house unsafe or uncomfortably cold. For more details, see best temperature for heat in house.

This range balances comfort with energy savings. Setting your thermostat higher than 70°F often leads to wasted fuel or electricity, while going lower than 68°F during waking hours can feel chilly indoors. The 68°F to 70°F standard comes from studies on human comfort and practical energy use: most people find this range comfortable wearing typical indoor clothing, and heating systems run efficiently without excessive cycling.

Dropping the temperature by 5 to 10 degrees at night or when no one’s home can cut your heating costs by up to 10% to 15%. For example, if your heater uses 1,500 watts, running it 8 hours at 68°F instead of 70°F might save you around 34 cents a day at 17 cents per kWh, adding up over the heating season.

How Temperature Settings Affect Your Heating Costs and System Lifespan

The most efficient home heating systems lose less fuel or electricity by maintaining steady, moderate temperatures rather than overheating the space. Lowering your thermostat by just 1°F to 2°F can reduce heating costs by about 1% to 3%. Over a month, that adds up.

Overheating your home wastes energy because heat rises and escapes through walls, windows, and ceilings faster at higher indoor temperatures. A 1,500 watt electric heater running 8 hours a day at 70°F instead of 68°F burns 24 more watts per hour, which over 30 days can cost you about $7 more at 17 cents per kWh.

Running Cost Example
Say your electric heater uses 1,500 watts and runs 8 hours daily. Lowering your thermostat from 70°F to 68°F saves roughly 3% on your heating energy. That’s 1500 W × 8 h × 30 days × 0.03 = 10.8 kWh saved. At 17 cents per kWh, the monthly saving is about $1.84.

Frequent large temperature swings—like turning the heat way up when you get home and off when you leave—make your system work harder. This cycling can shorten your heater’s lifespan by causing more wear on components like compressors or heating elements.

Programmable or smart thermostats help avoid this by keeping temperatures stable and automatically adjusting them when you’re away or asleep. They optimize efficiency while reducing unnecessary wear on the system.

Efficiency Tip
Choose a heating system with good insulation and a programmable thermostat to maximize cost savings and extend your equipment’s life.

For the lowest running costs, consider energy-efficient heating methods like heat pumps or well-insulated radiant systems. They provide steady warmth with less fuel or electricity compared to older or oversized furnaces.

Choosing the Right Thermostat for Precise Temperature Control

best temperature to heat house: Choosing the Right Thermostat for Precise Temperature Control

A thermostat with an accurate temperature sensor is key to keeping your home comfortable without wasting energy. The sensor detects the room temperature and signals the heater to turn on or off to maintain your set point.

Non-programmable thermostats offer simple temperature control but require manual adjustments, which makes maintaining the ideal 68°F to 70°F range less consistent. Programmable thermostats let you set schedules—lowering temperatures at night or when you’re away—to save energy automatically.

Smart thermostats add Wi-Fi connectivity and learning algorithms. They monitor your habits, adjust settings dynamically, and let you control temperature remotely via smartphone apps. This convenience can help prevent overheating or underheating when your schedule changes unexpectedly.

Humidity monitoring is another feature to look for. Dry indoor air can make a lower temperature feel colder, prompting you to turn the heat up. A thermostat with a built-in humidistat helps balance humidity alongside temperature, improving comfort and efficiency.

Compatibility matters too. Some thermostats work only with specific heating systems—like conventional furnaces, heat pumps, or electric baseboards. Check your system’s voltage and control wiring before buying to avoid installation headaches.

Thermostat Features to Confirm
Accurate temperature sensor to avoid overshoot or undershoot
Scheduling options for energy savings when away or asleep
Wi-Fi and app control for remote adjustments
Humidity sensing for better comfort
Compatibility with your heating system voltage and wiring
Thermostat Placement
Install the thermostat away from drafts, direct sunlight, and heat sources like lamps or appliances. Poor placement can cause false readings and inefficient heating cycles.

Who Should Skip Standard Temperature Recommendations?

Temperature fluctuations affect some households more than others, making standard thermostat settings less useful. Homes in the US use Fahrenheit, but individual needs can vary widely.

Safety Risks of Very Low Temperatures
Setting the thermostat too low can cause frozen pipes in poorly insulated homes and worsen respiratory issues for vulnerable people. Avoid dropping below 60°F unless you’re certain the house can handle it safely.

Families with infants, elderly members, or medical conditions often need warmer indoor temperatures to reduce health risks. Their comfort and safety outweigh modest energy savings from lower settings.

Very large or badly insulated homes lose heat quickly, forcing heaters to work harder. These homes might require higher thermostat settings or supplemental heating methods to maintain comfort.

Alternative heating, like radiant floor systems or solar heating, may not respond well to standard thermostat controls. These systems often rely on different temperature management strategies that suit their design and efficiency.

When to Adjust Standard Temperature Settings
Infants, elderly, or people with health issues needing warmer air
Homes with poor insulation or large open spaces
Use of radiant, solar, or other non-standard heating systems
Local climate extremes requiring adaptations
Risk of frozen pipes or health impacts at low temperatures
