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.
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 - Emerson Model CF788VNB-72

QUESTION: I am looking at the Emerson Carrera Grande Eco 72 (DC Motor) Ceiling Fan Model CF788VNB, however regarding fan blades for an outdoor-damp location, would these blades tend to warp over a few years in a humid environment? I have had many outdoor fans, and they almost all end up with warped blades over time. Do you offer blades that would be less prone to warping, or are these already "resistant"?
ANSWER: When you click on the orange button for blades, look for blades that say "(Outdoor Damp)". Emerson specially makes the damp rated blades from solid hardwood (instead of cheap plywood) that is treated to resist cracking and warping from being outside. They will hold up much better than what you have experienced and are in fact rated for use in outdoor damp locations by the manufacturer.

Ceiling Fans Question
QUESTION: I just bought a house with a Halsey ceiling fan and I want to add a light to it. The universal light kit only works sometimes! Where can I find Halsey light kits to fit models HC-HP and HG models?
ANSWER: I am sorry to report that Halsey went out of business several years ago, so finding parts for them is difficult. It is not a brand that we ever sold, so we would not have any fixtures on hand that were made by them. If you email me some pictures of your fan, I may be able to determine what types of universal fixtures will fit...if any. Email pictures to: email@example.com

QUESTION: The location I am considering was wired only for a light and no fan (1 wire pair). How do I tell which lights are compatible and which are not?
ANSWER: Almost all of our ceiling fans with lights do not require a second hot wire, so they will work with a 1 wire pair...there are very few exceptions. If you give us a call, we will be happy to help you choose the best fan for your needs and make sure you can install it.

QUESTION: How far down from the ceiling does the Seaside fan hang when installed with the flushmount option?
ANSWER: Thanks for your question: The Seaside fan from Savoy House comes with an 8" downrod as well as a flush mount adapter. The bottom of the fan cage hangs 16.3" from the ceiling when installed with the 8" downrod. Although the manufacturer does not specify the hanging distance with the flush mount option, after reviewing the installation instructions I have estimated that the flush mount option will reduce the distance by at least 6" to be safe...if not a bit more. That would put the bottom of the fan at about 10" from the ceiling.

Ceiling Fans Question
QUESTION: Do you happen to carry Hunter fan light fixtures that have a triangle base. These are not held in by screws but by a clip system.
ANSWER: I am sorry to report that we do not have any of the Hunter light fixtures you are looking for. Hunter only made the triangular fixtures for a short period of time and they discontinued them several years ago (too many problems). It is unlikely that you will be able to locate one anywhere. If you can email me some pictures of your fan along with the model number (located on a label on top of the fan housing), I may be able to come up with an alternative that will fit.

Ceiling Fans Question - Modern Fan Model VEL-HUG-BN-50-NK-NL-NC
VEL-HUG-BN-50-NK-NL-NC - http://www.hansenwholesale.com/ceilingfans/modernfan/model.asp?ProdNo=VEL-HUG-BN-50-NK-NL-NC
First off, I love all the consumer information Hansen Wholesale provides.
I'd love a clarification on something. You say that hugger fans don't work as well as regular ceiling fans. This makes total sense. However, why would the Modern Fan Velo Hugger be rated at the same 6650 CFM and 5.54 MPH wind speed as the regular Velo?
(Is it because the blades are installed as low as possible on the hugger fan, thus negating the height benefits?)
ANSWER: You are exactly correct. When installed with a standard downrod, the regular Velo hangs down the same distance as the Velo Hugger, so the airflow is the same.

Per the information on the site, the new DC motors, the Emerson K55XL, and other "induction" type motors are considered best quality. If that's the case, how do fans with smallish non-special motors (Say, Savoy House Indira, with 153 x 22mm motor) earn a 5 rating?
There are exceptions. A 5 rating is not just based on the motor inside the fan, but the overall consideration of the quality of the components and performance. Most 153mm motors are only 12mm to 15mm tall and tend to be overworked. The motor used in the Indra is 22mm tall, which is very unusual. This is a special motor that Savoy House had designed for this fan and the performance and quality of the motor are excellent. The 3-blade Indra produces a whopping 8517 CFM and runs very smooth and quiet. The entire fan was designed to produce maximum airflow while reducing noise. The blades have a very special aerodynamic design and the fan runs perfectly quiet. When I saw this fan introduced at the lighting show in Dallas, I was very impressed. Overall, one of the best fans I have rated in years. A DC motor would have been nice...but was not necessary to earn a 5 in my book.

Ceiling Fans Question - Minka Aire Model F513-WH
F513-WH - http://www.hansenwholesale.com/ceilingfans/minkaaire/model.asp?ProdNo=F513-WH
QUESTION: Hi, I have 4 rooms I'm thinking of installing fans. One is 10x14, 2 are 13x14, and a fourth is 23x15. For the first 3 I was considering Minka Aire F513. For the largest room I was thinking about Minka Aire MF-689. Will these be adequate?
Thanks, Tom Kelley
The Minka Aire F513 New Era fans will be great for the 3 smaller rooms. For the larger room, a single ceiling fan will not be adequate...you should install 2 fans. If you install 2 fans, then the F689 Kola-XL 60" fans would be a great choice. If you can only install a single fan, then I would recommend an even larger fan (up to 84") such as the Fanimation Odyn. Here are links to those resources: Large Ceiling Fans
