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 - Minka Aire Model F518-WH

QUESTION: If purchase fan, is it necessary to buy either RCS212 or WCS212 controls? There is only one switch on the wall to control fan. Without these optional extra controls, can I operate the light and fan separately? Thanks.
ANSWER: The Minka Aire Concept fans come with a hand held remote control for operating the ceiling fan. Your switch on the wall provides power to the fan. So in order for the remote to work the switch simply needs to be in the on position. You do not need to purchase any additional controls to operate the fan as it comes. If you wish to operate the fan from your existing wall switch, you would purchase the WCS212 wall control which converts it into a wall operated remote with the same functions as the hand held remote that comes with the fan. You would not need any extra wiring for the WCS212 to work. With the wall control installed, you can use both the included RCS212 remote control and the WCS212 wall control to operate the fan.

Ceiling Fans Question - Emerson Model CF205BS
CF205BS - http://www.hansenwholesale.com/ceilingfans/emerson/model.asp?ProdNo=CF205BS
QUESTION: The comments list an optional near flush adapter. My ceiling is 104 inches. Please advise.
ANSWER: The flush mount adapter is only recommended for ceilings that are lower than 8 feet. I would not suggest using it on your ceiling since it is over 8 feet high. When you use the flush mount adapter on any ceiling fan, it reduces the airflow of the fan because the blades get closer to the ceiling and the air cannot flow around them as freely as it does with a standard installation. Fans perform best when the blades are at least 12" from the ceiling.

QUESTION: My husband just purchased a Turn of the Century fan- Karlyn, model 355-0463. It is already installed but is too small and provides very little noticeable airflow. Can longer blades be used on this model?
ANSWER: Unfortunately you cannot buy larger blades for the fan that you own. Even if you could, it would not move more air, it would likely move less and eventually burn out due to the overloaded stress larger blades put on the motor. The Turn of the Century fans are very low end ceiling fans and have small motors in them that simply cannot perform. Fans like this are sold at places like Menards where people expect to find low prices and are not aware of the huge differences there are between various brands and models of ceiling fans.
Although we do not sell or recommend Turn of the Century fans, I took a moment to look at the specifications for the fan you and it is only designed to produce a maximum of 2169 CFM of airflow (Cubic Feet per Minute). This is extremely low when it comes to ceiling fans where the average airflow is closer to 5,000 CFM, and what I consider a good fan, will produce more than 6,000 CFM. Fans that produce higher airflow have much larger more powerful motors...and yes, probably larger blade spans.
I would suggest you spend some time looking through our website because our first and foremost concern is that our customers are aware of the amount of airflow each of the fans we sell can be expected to produce. If you start looking through our fan search results, you cannot miss the performance graphs that tell you exactly what you can expect from each fan. If you click on one of the graphs, you can read details about what to look for in a ceiling fan and how to compare them.
The 2169 CFM that your fan produces is ridiculous and I always feel for those who shop at home centers and unknowingly end up with a fan that does not move air.

Ceiling Fans Question - Hunter Model HU-53062
HU-53062 - http://www.hansenwholesale.com/ceilingfans/hunter/model.asp?ProdNo=HU-53062
QUESTION: I am wondering if you still carry a Hunter Model # 21543 ceiling fan. Looking for a high CFM, white, 52" ceiling fan with a 4 light kit that will accept 60 watt bulbs. Please email me with info.
Hunter no longer manufactures model 21543 and the fan has not been available for quite some time. I highly recommend you consider the Casablanca Panama ceiling fan. The Panama is one of the best performing high quality ceiling fans ever made and has been the industry standard for nearly 20 years. The Panama is a customizable fan that does not come with blades or lights, so you choose them separately to design the fan to fit your needs. The 4-light fixture options are one of the few that still come with standard medium base sockets that can accept 60 incandescent bulbs, although they ship with CFLs. Most 4-light fixtures from other brands either use candelabra base bulbs or plug-in type CFLs (to meet government regulations).
Casablanca recently introduced a special tool on their website that allows you to customize your fan and see how it looks before you buy it. Here is a link to that tool. Any of the fans you see on that site will be equivalent to the Panama, which is one of the choices. When you are finished building your fan, click on the checkout button and it will put your selected options into our shopping cart where you can finalize your purchase. We also have a promotion that will give you a FREE Casablanca Remote Control worth $80.00 when you buy any of the Custom Casablanca fans.Custom Casablanca Ceiling Fans
Here is a link to view the Casablanca Panama directly on our website where you can also select components individually but you cannot see how the completed fan will look, just the individual components:Casablanca Panama
BTW: The Hunter Studio Series ceiling fans are a lower end Hunter fan and they move only about half as much air as the Casablanca Panama...although the price is about half that of the Panama as well.

Ceiling Fans Question
QUESTION: Dear reader,
The fans from Casablanca are awesome and I would very much like to order two of these.
I'm living in The Netherlands and my question is if it's possible to get them in 220V instead of 110V. When this is not possible I would like to know if a power converter can help.
Your help is much appreciated and I would like to thank you in advance for your time an help.
ANSWER: Unfortunately Casablanca does not make any of their fans for use with 220V applications. They are only made for export and are only for sale in the USA.

Ceiling Fans Question - Minka Aire Model F510-WH

QUESTION: what is a three wire installation? I want to replace a ceiling light in my bathroom with a fan because I cannot install an exhaust venting one. Would this work? Or, do you have other suggestions?
ANSWER: A 3 wire control requires 2 hot wires...meaning 2 separate power sources. It would be the same wiring required to have 2 separate switches in a wall. Unless the location for your fan was pre-wired in this manner (which is rarely the case), you will have to hire an electrician to run an additional hot wire to the fan. The best option is to purchase the wall control model WCS223 because it only requires a single hot wire, which is what most people already have.
The information we had on our website was not accurate and the optional WCS223 was not showing on our site. There is also a remote control option RCS223 which will work with the Spacesaver and does not require a wall control at all. If you have an existing light switch that supplies power to the fan you can just leave it in the on position and use the remote control. I have updated our website with this information...and thanks for asking your question since it brought this to my attention.
FYI: When Minka Aire came out with the Spacesaver fan I made it quite clear to their executives that it was a mistake to not simply include the WCS223 or RCS223 control since most people would have to pay an electrician to run an additional wire ( at a cost of anywhere from $150 to $300) to use the cheaper 2 wire control they opted to include. Their response was that they wanted to keep the price of the fan below $200, so they chose to include a much less expensive control. Bad decision in my opinion because the 3 wire control can rarely be used. Otherwise, the Spacesaver is a great little fan and a good value at just under $220.00 once you add the WCS223 control...much better than hiring an electrician to run extra wires!
