Ceiling fans are commonly used for cooling purposes in the summer. But did you know that you can also use ceiling fans during the winter months to help distribute heat, enhance comfort, and even reduce your energy costs? In this comprehensive guide, we’ll explain how ceiling fans work in the winter and provide tips on how to use them properly to maximize energy savings and heating efficiency.
Ceiling fans don’t actually provide heat. Rather, they help circulate and distribute warm air that is already present, allowing you to feel warmer at lower thermostat settings. Here is how it works:
Warm air naturally rises and tends to accumulate near the ceiling, leaving cooler air near the floor. This can make rooms feel drafty and cold.
When operated in the proper direction, ceiling fans pull warm air down from the ceiling and push it out towards the walls and middle of the room.
This redistribution of warm air means the temperature feels more consistent from floor to ceiling.
With warm air distributed more evenly, you can lower your thermostat a few degrees without sacrificing comfort.
Nearly all ceiling fans have a small switch located on the motor housing that controls direction.
In summer, the fan should spin counterclockwise to create acooling downdraft.
For winter heating, reverse the fan so it spins clockwise on a low speed. This produces a gentle updraft that traps and recirculates warm air.
Make sure all the ceiling fans in your home are set to clockwise for winter heating operation.
Running your ceiling fans properly in winter can lead to measurable savings on energy bills.
Experts estimate using ceiling fans allows you to lower your thermostat setting by 4°F or more without sacrificing comfort. This can reduce heating costs by up to 15%.
Ceiling fans only use about 50 watts of electricity. Compare this to central heating systems that can use 3,500 watts or more. This makes fans an energy efficient way to maintain warmth.
Newer ceiling fans with Energy Star ratings are upwards of 60% more efficient than conventional models.
Strategic use of fans allows your heating system to cycle on and off less frequently, further reducing energy consumption and wear and tear.
Follow these tips to ensure your ceiling fans are providing optimal heating and energy saving benefits:
Run fans on low speed for winter heating. Higher speeds will only disrupt warm air circulation.
Consider installing ceiling fan remote controls or wall controls. This allows you to adjust fan speeds easily from your seat or bed.
Don’t leave fans running constantly when a room is unoccupied. Use timers or occupancy sensors to automatically shut off fans.
Run fans for at least 15 minutes after leaving a room. This will redistribute heated air and allow the room to stay warm longer.
In most cases, a 12° blade pitch is ideal for air circulation in winter. Higher pitches above 16° provide little added benefit.
Adjust blade pitch controls (if equipped) to fine tune airflow.
For rooms larger than 500 square feet, consider installing multiple ceiling fans to ensure sufficient air circulation.
Position fans strategically to direct air flow across the room and toward seating areas.
The heat from ceiling fan light kits can provide added warmth when used along with a heating system.
Use efficient LED lamps in fan light kits to produce heat with minimal energy use.
Place fans at least 7 feet above the floor and 18 inches from walls for optimal air flow.
Avoid obstructing fans with objects like bookshelves, furniture, low-hanging lights, etc.
Replace any warped or unbalanced blades that may disrupt air flow.
While ceiling fans provide noticeable heating benefits, they cannot replace central heating systems as a primary heat source when outdoor temperatures drop significantly below freezing. Here are some ways to use them effectively as a supplemental heat source:
When temperatures drop below 20°F, rely more on your primary heating system by raising the thermostat to normal heating levels.
You can run ceiling fans to provide added comfort and distribute heat at normal thermostat settings. Just don’t expect them to allow substantial thermostat setbacks.
Consider running fans on timers to distribute heat for 30-60 minutes after your central heating system cycles off. This can extend the period of comfortable warmth.
Focus on using ceiling fans to distribute heat in frequently occupied high-traffic areas like living rooms. Run central heating less in unused rooms.
In rooms without fans, close vents partially to force more warm air into primary living spaces.
Zone heating involves heating different areas of your home to different temperatures based on occupancy patterns. Ceiling fans allow you to effectively zone heat your home:
Set programmable thermostats to lower temperatures in unused bedrooms, basement, etc.
Run ceiling fans as needed in occupied rooms to provide comfort at lower thermostat settings.
Close vents partially in unused rooms. Limit the central heat pumped into these non-occupied areas.
Zone heating reduces the energy wasted bringing seldom-used spaces up to uncomfortable temperatures.
If your ceiling fans seem ineffective at providing warmth in winter, consider these troubleshooting tips:
Double check the fan directional switch is set properly to clockwise/updraft mode.
Clean fan blades and motor housing to maximize air flow. Dust buildup inhibits air circulation.
Lubricate and inspect moving parts. Fix any wobbly or warped blades.
Verify blade pitch is optimized for heating. Adjust if equipped.
Replace burned out light kit bulbs to provide supplemental radiant heat.
Make sure fans are placed correctly in relation to room dimensions. Add more fans if needed.
Check for accidental setting changes on remote controls or wall controls.
Have a professional inspect fans and conduct airflow tests to identify and correct any issues.
If you are looking to purchase new ceiling fans for better winter heating, keep these key considerations in mind:
Look for fans with reversible motors that allow switching between downdraft and updraft modes.
Select models with highest rated CFM (cubic feet per minute) airflow to maximize heat circulation.
Choose Energy Star rated fans with DC motors for optimal efficiency and energy savings.
Pick fans with blade pitch optimization controls for customizing airflow direction.
Buy fans with light kits and space for the highest wattage bulbs allowed.
Look for quieter fans rated under 1.5 sones at their highest speed.
Consider smart fans controllable via app, voice assistant, or home automation system.
Be sure to get fans of the appropriate size and style for each room’s dimensions and décor.
Proper installation and wiring is critical to ensuring new or existing ceiling fans operate safely, efficiently, and effectively in heating mode. Consult a qualified electrician for:
Evaluating wiring needs and circuit capacity before fan installation.
Correctly wiring the ceiling box and any controls like dimmers.
Hanging and securing fans to ceiling joists and beams safely.
Testing fan directional modes and controls during commissioning.
Addressing any electrical issues with older fans and wiring.
Optimizing whole house fan placements and zones for maximum comfort and energy savings.
The bottom line is that ceiling fans can absolutely provide noticeable heating benefits and energy savings when used properly in winter. By circulating trapped warm air, they allow you to lower thermostat settings comfortably and reduce reliance on central heating systems. Follow our tips outlined above for maximizing ceiling fan efficiency and savings. And be sure to enlist a professional electrician for any new installations, wiring, or troubleshooting needs.

Is it best to leave ceiling fans on all the time?
Fans can have a big impact on air circulation and perceived temperature, but that all depends on the people in the room to feel that air. Leaving fans running when there is no one to benefit from the air is simply wasting electricity. Also, most fans run on motors that produce heat when running.
