How to Position 2 Ceiling Fans in a Single Room

Some rooms are simply too large for a single ceiling fan, or the ceilings are so high that it makes more sense to use 2 fans instead of one. In general, rooms that are larger than 20' x 15' will be better served by 2 moderate size ceiling fans rather than 1 large fan. Rooms that are a bit smaller but have much higher ceilings can also use 2 fans for better circulation. So if you want to install 2 fans in the same room, it is important to know how to space them out properly for optimal performance.

To illustrate how to position 2 ceiling fans in a room, we are going to use a room size from someone who most recently asked us how to do this. The room was 17 feet x 15 feet with 17 foot high ceilings.

The goal is to postion the fans equidistantly in the room. The end result with be that the space in the center between the 2 fans is twice the distance that the fans are from the walls. This is accomplished by dividing the width of the room by 4 and centering each fan that same distance from the side walls.

In our example room that is 17 feet wide (which is 204"), 1/4 of that distance is 51". So each fan should be installed with the junction box positioned 51" from the shorter wall. Although the measurment is now shown in the illustration below, you would also position the fans in the middle of the shorter 15 foot wall, which would be 7 1/2 feet from either side.

Illustration:

You can check this calculation using this method: Subtract the combined width of the 2 fans (104") from the width of the longest wall (204"), which in your case leaves 100" of space not occupied by the fans. Divide 100 by 4 to find out how far from each wall the blades will be (25"). Then divide the span of the fan by 2 to find the radius or center location of the fan (26"). Then, add the distance from the wall to the radius of the fan to locate the distance from the wall to position the fan mounting hardware on your ceiling. In this case that is 51" (25" plus 26"). This will leave 25" from each wall to the blades and 50" between the blades of each fan as shown above.

    Ceiling Fans Question

    http://www.hansenwholesale.com/recommendations.asp

    QUESTION: how big of a fan will I need for a room this big 20 feet wide 30 feet long and 26feet hith

    ANSWER: Your room is too large for any single ceiling fan. I would recommend 2 60" to 72" fans and you will most likely need to purchase two 6 foot long downrods and a downrod coupler for each fan so you can join the downrods together to create 12 foot long downrods. If you can only install a single ceiling fan, I would suggest using an 80" fan. Please call us so we can go over your options and help you select the best fan(s) for your application.

    QUESTION: will a 1994 wall for a intelertouch and rods work with a new fan ?

    ANSWER: No, the inteli-touch system is antiquated and not compatible with new Casablanca fans. Casablanca has also changed their mounting hardware and downrods, so the older downrods will not work either.

  7. Question #9473 - Posted: 4/4/2014 8:12:01 AM

    Ceiling Fans Question

    http://www.hansenwholesale.com/ceilingfans/sizes.asp

    QUESTION: We have a small office, 9 feet by 11 feet. We just put in a wall to wall, floor to ceiling built in cabinet. The ceiling fan, which centered in the center of the ceiling, is not now. It is closer to the built in and it seems more air is being pushed toward the built in. Is this the effect of the built in? Can anything be done to push more air to the desk, which is opposite the built in?

    ANSWER: The built in cabinet is likely impeding the natural airflow pattern of the fan, which can cause it to move less air. Several options: 1) Relocate the fan closer to the desk. 2) Buy a larger fan. 3) Buy a more powerful fan of the same size. The amount of airflow a fan is capable of producing is measured in CFM (Cubic Feet of Airflow per Minute). You will find it easy to compare the CFM between all of the fans on our site (where CFM is available). Give us a call and we will be happy to go over these options in more detail. If you can email me some pictures of your room, I will be happy to take a look and see if there is anything else I can suggest. Email pictures to: gregt@hansenwholesale.com

    QUESTION: Is it possible to use dimmable CFL bulgs in Midway Eco and will remote allow them to dim?

    ANSWER: Unfortunately the Emerson Midway Eco remote does not have a dimming function, so although you could install dimmable CFL bulbs, you would not be able to dim them. As I have mentioned previously, the lack of dimming capability is the only complaint we get about this fan...and rightfully so. This is a problem for virtually ALL ceiling fans with lights from ALL brands that meet Energy Star requirements. If you really need dimming capability and are looking for a ceiling fan that has a DC motor, I would suggest you consider the Casablanca DC Stealth. The DC Stealth does not meet Energy Star requirements because it incorporates a 100 watt halogen bulb, but it does have a super efficient DC motor. Casablanca chose to go that way in order to meet the needs of people looking for a high quality contemporary style ceiling fan with a super efficient DC motor and a dimmable light. Here is a link to the: Casablanca DC Stealth Model 59105 in White.

  9. Question #9470 - Posted: 4/3/2014 8:17:20 AM

    Ceiling Fans Question - Emerson Model CF787ORB-72

    View  model CF787ORB-72
    CF787ORB-72 - http://www.hansenwholesale.com/ceilingfans/emerson/model.asp?ProdNo=CF787ORB-72

    QUESTION: Model CF787ORB comes with a 4 speed wall control. How does it reverse the fan blades direction ? It is located at 20feet off the ground

    ANSWER: The Emerson Carrera Grande has a manual reverse switch on the motor housing. Because your ceiling is so high, reversing the fan manually is obviously not going to happen. Emerson makes a special remote control transmitter and receiver that is capable of reversing the fan. This remote can be installed as a wall control and also be used as a hand held remote. Here is a link to the components: SR650-RC212. They also have another remote only option with a receiver that cannot be used as a wall control. Here is a link to that system: SR600-RC212. Although the receiver is not shown in the picture, it is included in the model that we are selling.

    Keep in mind that in order for these to work, you must install the receiver unit in the canopy of the fan when you install the fan. If you do not install it then, you will have to get up there to do it later...so be sure to purchase these components along with your fan. Also, rather than using the links above to purchase these parts, you can simply add them to your original fan purchase by clicking on the orange button labeled "Controls" below the picture of the fan on the main product details page...or just give us a call and we will make sure you get everything you need.
