What would you like to do?
I've a 4 ft diameter ceiling fan with 3 blades of std width (about 3") hanging at a distance of 9" from the ceiling. Floor to ceiling distance is 8'5". Problem is that when I stand at a distance of about 3 to 4 feet from the centre of the fan - there is no air-flow. So, area covered by fan is 8 ft dia (max). If I stand beyond 8 ft dia circle there is hardly any air flow. Same fan in another room is hanging at a distance of about 12" to 13" and it's covering area 12 ft dia on the floor with a reasonable air-flow. It seems that there is some co-relation between height of fan from ceiling and area covered below it. Any idea? ceiling fan The distance from the ceiling is of little importance unless ceiling is very tall. Size of fan, width of blades makes the difference. Pitch of the blades The angle, or pitch, of each ceiling fan blade is also a determining factor in how efficient a ceiling fan will be. The angle of the blade affects the amount of wind resistance and the fan's ability to blow the circulated air downward.

Answer The distance of their palm.
Three bladed ceiling fans are mostly modern and have three blades for the modern look. Most ceiling fans have five blades. Many have six and some have 4. Also there is a one b…laded ceiling fan made by Fanimation Ceiling Fans. http://www.rlights.com
It is certainly NOT recommended. You will be better off to purchase a new set of blades.
A possible reason is that the start-and-run capacitor on the fan motor has developed a fault, meaning it has gone wrong and doesn't work to start the motor any more. If y…ou flick the fan blades and that spins the motor enough to get it moving, if it continues running until it next gets switched off, then you know the start-and-run capacitor has died. As you asked this question here, it is unlikely you are already a licensed electrician, so you will need to call one to get this fault fixed, or have a complete new ceiling fan installed. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use an electrician's test meter having metal-tipped probes (not a simple proximity voltage indicator) to insure the circuit is, in fact, de-energized.
ceiling fans only push the air around them, they have no cooling fuctionality. Ceiling fans don't have any way of cooling the air they circulate, but that is also t…rue of fans placed on work desks or floor stands. However the human body feels more comfortable if the skin feels cool, and fans help to do this by evaporating more moisture from the skin, due to the flow of air over it. However there are certain aspects that should be taken into consideration; 1-that energy transfer takes time, and when air moves it does not transfer its heat to the body because the time of transference decreases, for example if you holds a hot cup of tea you will get burned, but if you touched it quickly you won't be burned. 2-Also if the temperature is low and you are covered by a blanket you will the air inside that blanket and you will be warm, accordingly if there is a fan the air won't stay around your body to be warmed. 3-Finally when air circulates this will increase the amount of air inside the room thus more air will absorb more heat from your body(if the air's temperature is less than the body' temp) until the thermal equilibrium occures. If there is no one in the room to feel the moving air then there is no effect other than wasting electricity to run the fan. Window fans on exhaust or intake do have a cooling or warming effect depending on the outside air.
At least 7 foot.
Most fans come with balancing weights. If you have none now, it's possible to use plasticine or modelling clay. Possibly the most difficult thing is deciding WHICH blade needs… the weight. I'd suggest numbering them discreetly and then applying a small weight to each in turn to see if balance improves.
personal preference, aesthetics's. It only needs one but would be unbalanced, two is the practical minimum
You turn it on.
If you have a HOT fireplace room in your house which direction should ceiling fan blades turn to push the heat into OTHER rooms?
You will likely find that a ceiling fan will not satisfactorily circulate air between rooms. However, you will find that setting the fan rotation to circulate air from the ce…iling to the floor will maintain a more even room temperature since hot air rises. Some people prefer to set their fans so it pulls the air from the floor to the ceiling if the draft from the fan is uncomfortable.
It does not actually reduce the room temperature. It makes the room feel cooler by convection. the cooler air blows past your skin, cooling it by evaporation.
The blades are generally held on by 3 screws, you simply remove these, fit the new blades and use the same screws to fit them.
If you need to replace the entire ceiling fan, you can buy replacements at Lowes, Home Depot, or even most lighting stores. If you just need new fan blades, Lowes and Home Dep…ot carry replacements for the most common brands, or you can contact the manufacturer. Answer The Habistore (Habitat thrift store) and other thrift stores sell a set of blades for around $15. Last I was in there, there were many choices.
These days with most fans being installed with variable speeds the difference between 4,5 or 6 blades is mostly an aesthetic thing and air movement is similar with all styles.… Blade dimensions (length) seem to make the most difference, and the distance from the ceiling.
Fans don't cool the air; they actually make it a little warmer. Bycausing more air to cross the surface of your skin, fans increasethe rate of evaporation of your perspiration…. The process ofevaporation draws heat from your body, making you feel cooler. Theless water vapor that is in the air, the more rapidly the bodycools.
