EVERYTHING YOU NEED TO KNOW ABOUT CEILING FANS
Are you looking to replace the aging light fixtures found throughout your home with an updated, multi-functional alternative? You may want to consider all the wonderful advantages ceiling fans have to offer.
Ceiling fans can boost your “cool” factor.
And we’re not just talking about their aesthetically pleasing ambiance. Ceiling fans are a practical, economical solution to reducing your cooling needs in the summer. By creating a wind chill effect, using ceiling fans throughout your home can keep you and your family comfortable enough to lower your thermostat temperature by 4-7 degrees F, saving you up to 30 percent on cooling costs. Still on the fence? As an added bonus, the wind generated by ceiling fans also makes it more difficult for pests to fly, keeping summer pests at bay. How’s that for cool?
Ceiling fans can make the most out of your heating system in the winter.
Say what? That’s right. Change the settings on your ceiling fans to spin clockwise, rather than their counterclockwise motion during the summer, and you’re in business! A clockwise motion forces air up, to the outer edges of the room, then down along walls to the floor, where it travels back to the center, once again rising. This motion helps equally distribute all that nice heated air from your HVAC system throughout your home, saving you much needed heating dollars.
How do you find the perfect spin?
Stand under your fan, and note the direction in which the blades rotate. (Don’t worry, it doesn’t matter which direction you face.) Remember, you want your blades to spin counterclockwise in the summer, clockwise in the winter. Wrong direction? Turn off the fan and locate the switch on the fan’s base, then simply flick the switch to the opposite direction. Done!
Ceiling Fans Heat The Room
Yes, a ceiling fan is a cooling device. (See number 2 below.) But its effect on the room it’s in is to add heat. Why? Because electric motors are devices that turn electrical energy into mechanical energy, most of which ends up as heat. The infrared image below shows a ceiling fan motor that’s hotter than the room it’s in. From the second law of thermodynamics, we know where that heat is going — into the cooler room.
Bigger is better with ceiling fans
While you’re checking those labels, you may notice a correlation. The fans with the longest blades have the highest efficacies and those with the shortest blades have the lowest. That’s why the company Big Ass Fans makes big ass fans. And it’s why you’ll want to avoid the little short-blade fans like the one above, no matter how cute, if you’re interested in air flow. If you just want cute, though, go right ahead.
How Do DC Ceiling Fans Work?
The quick answer:
The DC motor starts up when a small electric current is passed through a magnetic field coil. The resulting magnetic force produces the torque that turns the motor repeatedly.
The detailed answer:
The specific type of DC motor used in ceiling fans is a brushless DC motor (aka synchronous DC motor). A DC motor uses an internal array of magnets of opposing polarity. This creates a magnetic field that creates the torque required to rotate the motor’s rotor. This process requires less electrical energy, translating into a 70% or greater reduction in power consumption over standard AC motors.
Reasons To Use Your Ceiling Fan In Summer Mode
By using your ceiling fan in Summer, you can save up to 40% on air conditioning costs. This is due to the fact that circulating the cool air with a fan means you can reduce the use of air conditioners. Further, fans create a wind chill effect on your skin, making a room feel up to 8 degrees cooler.
In Summer, a ceiling fan pushes cool air down, evaporation perspiration and creating the wind chill effect mentioned above. This allows you to feel cooler without affecting room temperature. Further, an outdoor fan can help you feeler cooler, allowing you to spend more time outdoors or entertaining.
REASONS TO USE YOUR CEILING FAN IN WINTER MODE
As in Summer, using your ceiling fan in Winter help redistribute warm air around the room. This can save you up to 15% on your heating costs. It also reduces the cost of heating fuel, electricity, or gas. It can also reduce the clutter created by heating devices. Modern ceiling fans will have a Winter mode, that allows your fan to redistribute warm air around the room and your home in general.
In Winter we close up our homes to heat them and retain the heat. But this creates limited circulation through the home. As a result, the warm air rises and you don’t feel all the benefits of your heating system.
Putting your fan in Winter mode allows the fan to draw air up into the centre of the room, then redistributing it down the walls to the floor, mixing the air in a room. This actually warms the room up more than just heating alone.
When air is no longer stagnate in a room, meaning there is less condensation and humidity in your room. It also lowers the risk of dehydration.
Choose The Right Blade Size And Features
While choosing the right sized fan is important, you also need to choose the right blade size and features.
Choosing the Right Fan Blade Size
The number of fan blades doesn’t make much difference, but the size of the blades do. Choosing larger blade sizes over smaller blades. Larger blades won’t ruffle papers and other items as much, and can cool at a lower velocity. However, ensure you don’t choose a size that is too large for the room. Refer to our “Ultimate Ceiling Buyer’s Guide” for more information.
Pick the Right Features
Easy to use ceiling fan models, like those from Martec, encourage fan use over air conditioning, which results in lower energy costs. But it is also important to consider the light intensity, fan speed, noise level, and remote controls.
Choosing the right motor is an important part of ensuring your fan doesn’t make too much noise. Always choose high quality motors with solid bearings. Smaller, less powerful motors tend to operate at higher temperatures – which makes a room warmer – and make a lot of noise. They’re also likely to break easily.
Finally, it is important to choose the colour/finish, lighting style, and look for your space. There are a wide range of styles and finishes for modern ceiling fans, meaning you will find the look and style you want. Lighting options are fantastic, as well, with single lights, spotlights, and more available.
