How far to hang ceiling fan on 20 foot ceiling?

5 years ago

I purchased a 60" ceiling fan for our great room which is 19.5 feet high and has a 10/12 pitch. We will be heating with wood using a Wilkening Fireplace so want to properly move the air around. Everything I'm reading says that the fan should be 9 feet off the floor, which would mean I would need a 10 foot down rod which seems ridiculous! Would I be making a mistake if I just hung it as far down from the ceiling as is visually appealing to me? Since scaffolding is needed, I would really like to get this right the first time!! Thanks in advance for your help!

RIGHT FAN INSTALLATION:

https://www.airconditionersductless.com/

Ceiling fan blade spans range from 29 – 54 inches - the most popular being the 52-inch model. To determine which size you need, measure the room where the ceiling fan will be installed and follow these guidelines:

Room Dimensions Suggested Fan Size

Up to 75 ft2 .....29 – 36"

76 – 144 ft2 .....36 – 42"

144 – 225 ft2 ......44"

225 – 400 ft2...... 50 – 54"

Choosing the Appropriate Mounting System

Ceiling fans should be installed, or mounted, in the middle of the room and at least 7 feet above the floor and 18 inches from the walls. If ceiling height allows, install the fan 8 - 9 feet above the floor for optimal airflow.

Standard mounts come with a 3 – 5 inch downrod, which is the metal pipe that extends from the ceiling bracket to the top of the fan. Downrods are usually either 1/2 or 3/4-inch in diameter.

Extended mounts can be used to hang the ceiling fan at the desired 8– 9 feet from the floor for tall ceiling heights. Downrods can be purchased from 6 inches (9 ft ceiling) to 120 inches (20 ft ceiling). Check with the manufacturer or sales associate to determine the right downrod length for you.

Flush mounts anchor the fan directly against the ceiling. Most standard fans can be installed as a flush mount however, many manufacturers sell “hugger” or “low profile” ceiling fans that are specifically designed for this purpose. Hugger fans are ideal for rooms that have ceilings under 8 feet in height or in situations where a fan with optional light would hang down too low. Hugger fans will not move as much air as a regular fan because the blades are closer to the ceiling.

Your downrod is not long enough and frankly it's the pitch of the blades that affects air flow. Is your fan large enough for the room?

Most charts say call the company to discuss for ceilings over 15' tall. Longest stock downrod that seems easily available is 6'/72".

Regardless, you need at least 2' from fan tips to wall at whatever height you suspend.

How expensive are 12 foot ceilings?
Q
Comments (9)
The last house we lived in had 12 foot ceilings downstairs and 9 foot upstairs. When we walked through that house, the 12 foot ceilings made every room feel so spacious! Then we moved in... For some rooms (like our 17' x 19' master bedroom) the 12 foot ceilings were, in fact, very nice. The room's proportions worked well and the space felt luxurious. But for most other rooms, they just felt 'off'... The powder room felt like an elevator shaft. The master closet had clothes rods 10 feet off the ground! The kitchen and master baths felt like hallways, even though the rooms were 12-13 feet wide. The breakfast room felt like a tower. The two-story family room felt like a hotel lobby! And almost every room felt 'exposed'. Too open. There was no 'cozy' to be found anywhere in that house. Our current house has 8' ceilings in most spaces, with some small areas of 7'6" and one 18' area. At first, I was worried that the 8' ceilings would feel so low! But I really came to appreciate them, and to appreciate what the variations in ceiling heights did to improve the 'feel' of our home. There are open spaces, cozy spaces, transition spaces... Having lived with them, I would strongly urge you NOT to put 12 foot ceilings everywhere in your house. For rooms whose smallest dimension is 15 feet or so -- then IMO, they work. But for smaller rooms, DON'T DO IT! Nine or 10 feet are plenty high enough to feel open and spacious in a good way.

You can buy rods of varying length. You basically want the fan to be at around 8' from the floor. I placed mine at a point that was around 10' and used a 2' rod (or was it 18"? I don't remember) to put is around 8' off the floor. That still allowed be to reach the reversing switch.

How much cooling does a ceiling fan provide for sleeping?

Our Minka Aire Concept II 44" fan was installed this week, just in time for our first serious heat wave of the summer. It was 100 degrees yesterday and 83 upstairs at bedtime, a perfect night to sleep in the guest room and try out that baby. I put it on high for about half an hour while I read. It cooled me down instantly, but I didn't want to sleep with it on high because it makes a little wind noise, but less than a table fan. I switched it to whisper-quiet medium for the night. I never felt hot once. Thanks to all the great help on this thread, I got a great fan and a comfortable guest room for summer visitors!

Hi wantoretire_did! Thank you so much for the suggestions! I've been meaning to get to HD and my local ACE for a walk-about. I'm going to go when I have a couple of hours and don't have to rush around. Just walk around with my trusty legal pad and take notes. Lighting is a big part of what I want to look at. I really appreciate your suggestion because that didn't even cross my mind! I'm pretty sure most, if not all, of the fixtures in my house are original, and at 37, they need to retire, lol! I just can't see paying some guy from CL for the rest of my life to come replace bulbs and wash the fixtures! I have electric burners, but I can see how that could easily happen with gas. I'm pretty much leaning against the ceiling fans now; cathyyg made very good points, and these seven ft. ceilings feel so low already, even at my height, that I fear the fans would just draw attention to them. We've got a good system with the fans now, and I don't think ceiling fans are as necessary as I thought they were when I first posted this. Yes! Taking lots of pictures! :-) I hope all is well with you and yours!

Jennifer- did you ever get your ceiling fan resolved? I have the same issue, we are re-building our lake home (and interestingly we are using a Wilkening fireplace also!). LMK what you ended up doing. My electrician suggested hanging the ceiling fan very high up but the fan company says we won't feel the air flow even with a 7500 CFM. Thanks for any help. Julie

I ended up hanging it about 5 feet from the ceiling, so fairly high. I'm very pleased with it. A lot for me was the view of the lake (I didn't want to have to look through the fan to see the lake from the second floor balcony.) It moves the air just fine both directions depending upon the season. I DID, however, end up with the "strobe affect" which my electrician warned me about. I thought I was hanging it high enough to avoid that, but I guess not!

Just be aware that the longer the down rod, the more susceptible to imbalance the fan will be. With the quality of fans today, you could have your fan swinging around like one of those aeroplanes you see in the toy stores!

Our family room has a vaulted ceiling, 16' to the peak and a ceiling pitch of 8/12. We installed a 60" fan and when it came to the down rod, I bought a 6 foot rod at Lowes, it was the longest they had. That places the fan at about 10'off the floor. Works fine for air circulation. I wouldn't be so concerned about the look, we don't pay attention to the 'look' of the fan, it's the fireplace, brick surround and built-in cabinets on each side that what we see in the room.

I disagree with sktn about a longer down rod making the fan more susceptible to imbalance. Fans mounts allow the down rod to pivot at the top/ceiling mount. This makes the combination of the down rod fixed to the fan act as a long pendulum. The longer the pendulum length, the longer its period of swing (as the pendulum is lengthened, it swings back and forth slower). With an out of balance fan assembly, the period of rotation of the fan is short (1/2 second?, 1 second?) when compared with the period of the pendulum (several seconds) such that the out of balance condition doesn't excite the pendulum frequency.

What is a strobe effect?

As I understand it, it is when the paddle of the fan cuts through the beam of light as it is shining down into the room. So it "cuts" the light out like a strobe light does. The faster you run the fan, the strobe effect you get.

Where can you buy a 96” down rod?

Down rods max out at 72". You can use two down rods and a down rod coupler for longer lengths. Check with the maker of your fan to ensure matching finish.
