Tips for Setting Up Your Outdoor Fan-ipanergy

Some of your outdoor fan's set-up goes into the category of trial and error. When you put your fan where you want to use it and turn it on for the first time is when you'll begin to really see how much air it moves and start to get an idea of how much cooling it will provide. As you adjust the fan's settings such as speed and angle, you'll be able to see how much the set-up influences the cooling.

Your Fan Needs Unrestricted Air Flow

To be most effective, fans need to have open space all around them or "unrestricted air flow." They need to be able to freely pull air in from the back and freely blow it out the front. The larger or more powerful the fan, the more space it will need. Small tabletop fans may only need a foot or so (30cm) of clearance. Large standing fans may need about a yard or a meter.

Ceiling fans need at least 12 inches / 30 cm clearance from the ceiling to be most effective. For really high ceilings you'll want to use long downrods to lower the fan down to where people can feel its breeze. The distance from the ceiling may need to be less when the ceilings are low because of safety concerns -- a ceiling fast must be well above head height. That is, it must be at least 7' - 8' (210 - 240cm) above the floor.

If you have a low ceiling, mounting your fan a safe height may not allow ideal clearance above the fan. You can get low-ceiling mounts or "hugger" style fans that will let you install the fan closer to the ceiling, but its air flow won't be ideal. Still, it will ensure no one gets hurt by reaching up into a running fan.

You can counter the diminished effectiveness of a fan with inadequate air flow

by using more, smaller fans to cool the same sized area, or by using other types of outdoor fans such as standing or table top fans. The smaller fans won't need quite as much clearance, and spacing them around the area will provide the whole area with a cooling breeze. Be sure to allow at least 24" / 60 cm between the blades of multiple fans.

Angling the blades of standing fans slightly upward increases the area they affect. Why? Because if the fan is blowing directly horizontal, the ground diminishes that area of air flow. It would be almost like placing the fan partly behind a wall. Anything blocking that air flow will lessen the fans effectiveness. That includes people, too.

Though it can feel great to have a fan blowing air directly on you, if there's anyone behind you, they won't be able to feel the breeze because like a wall, your body is blocking the air flow. An advantage of ceiling fans is that the air flow comes from above our heads so there is nothing really to block the air flow. This is also an advantage of oscillating fans because they regularly shift the position of the air flow.

The Way You Set Up the Fan Can Affect Its Noise Level

The noise an outdoor fan makes can be made louder or quieter depending on how it's set up. A fan vibrates when it's running and this makes noise. A standing fan might make a louder vibrating noise on a cement floor than it would on a lawn. A wall or ceiling fan's vibration could be either muffled or amplified depending on how securely it's installed and how the wall or ceiling is constructed.

The space around it also affects the noise level of the fan -- the more enclosed the area, the louder the fan. An outdoor fan in a enclosed patio will seem louder than the same fan in an open area.

Here are a few guidelines to follow to ensure your fan is set up safely:

  • The wiring must be safe. Connections need to be waterproof -- all wired must be insulated. Wrapping them tightly with electrical tape (which doesn't let electricity pass through it the way regular tapes do) or Teflon tape is a simple solution.

  • Electricity must be grounded. Your outdoor-rated fan should have a grounded (earth return) 3-prong plug to reduce the risk of electric shock. GFCIs (Ground-Fault Circuit-Interrupters) are another measure you can take to prevent electric shock. More and more fans are including GFCIs as part of their cords. They can also be purchased separately and plugged into the outlet before the plug is inserted into it.

  • Fans should never tip over or be knocked over. Permanent installation should be solid and secure against extreme weather and against being knocked into. Temporary installations need to be clearly visible or completely out of the way; fans likely to tip over must be secured to the ground. Heavy weights on the fan's base are one possible solution, but make sure the weights cannot be tripped over.

  • Nothing should be able to fall or reach into the fan blades. Residential ceiling fans should be mounted a minimum of 7 feet / 2 meters (even higher is safer) from the floor and a minimum of 10-12 inches / 25 - 30 cm below the ceiling (your ceiling should be more than 8 feet / 2.5 meters high to use a ceiling fan). 10 feet / 3 meters from the floor is the minimum for ceiling fans in businesses.

    All fans except ceiling fans should have safety cages around the blades unless the blades move too slowly or the fan isn't powerful enough to cause any damage. The smaller the openings of the cage screen, the safer the fan.

  • Electrical lines (cords) that run from the electric source (house current, commercial current, generator) to the fan itself must be secured to the ground or hung out of the way so they will not be tripped over or run into.

  • Your outdoor fan's set-up must follow local ordinances, including rules of use by any private person or group that oversees the area you will be cooling. Contact them for details.
