Ceiling fans have a very long history. It was in 1882 when the first electrically powered ceiling fan was invented by Philip Diehl. Since then, the ceiling fans have come a long way. Even today, the ceiling fans are considered an important component of most residential and commercial spaces. A wide variety of fans are available in the market today ranging from simple to designer from manually operated to remote operated and from solo function to multi-function fans.
The contemporary designer ceiling fans exhibit a perfect amalgamation of functionality and design. The fancy and designer ones that are available in the market today not only provide you with cool breeze in the summer, but they also act as an embellishment to your home and/or office. Whether you want to buy ceiling fans for your home or office, you should keep certain things in mind in order to make a wise choice.
We have listed here for you 5 important points to keep in mind when buying a ceiling fan:
1) Fan Size
The first important thing that you will notice while purchasing a ceiling fan is that these appliances come in different sizes. Their size is measured by the span of the blades or by measuring the diameter of the circle that is made by its rotating blades. So, the size of the ceiling fan you are choosing must suit the size of your room. You may use the following estimates to assess the fan size suitable for your purpose:
For Small size room (bathroom, kitchen, etc.) < 80 sq. ft. – blade span 24” to 42”
For Medium size room (bedroom, guest room, dining room, etc.) 100-150 sq. ft. – blade span 44” to 50”
For Standard size room (bedroom, living room, etc.) 150-300 sq. ft. – blade span 52” to 60”
For Large size room (master bedroom, living room, etc.) > 300 sq. ft. – blade span 60”
The above figures are approximate. You may also take other influencing factors (if any) into consideration while deciding on the size.
CFM or cubic feet of airflow is another important factor to consider while buying a ceiling fan. CFM determines the cooling effect that a fan can create; a higher CFM means higher cooling effect and vice versa. A bigger motor delivers higher CFM, but this expense on bigger motor is worth bearing as it leads to saving on power bills by reducing the need for air-conditioning. The recommended CFM figure is 6,000 to 7,000.
As discussed above also, a fan with a bigger and larger motor is worth the expense as it reduces the need of air-conditioning and therefore, cuts down on power bills. In addition to this, there is one more thing that you should not only choose a motor with higher CFM, but you should choose a DC motor. These motors are little expensive than the conventional fan motors, but it is only a one-time expense which provides great convenience later. The powerful DC motors in these appliances are capable of cooling a large space with a silent operation. You don’t have to bear that continuous annoying sound as these motors are designed to provide optimum comfort with minimal noise.
Blades are a vital component of any ceiling fan. This is the first thing that people look at. Probably, this is why many fan manufacturers are coming up with fancy, colorful and designer blades to woo the prospective buyers. But, what is much more important than the color or shape of the blade is their number and angle. A triple-blade fan is quite efficient in comparison to those with four or five blades. This is due to the reason that less blades cause lesser drag. But, this is also true that four or five blade fans are relatively quieter and bear an aesthetic value as well. So, the choice of more blades or less blades is purely subjective. Now coming to the angle of blades, anything lesser than a 12 degree angle is considered too flat. So, you should look for a fan having blades angled at 12-14 degrees at least.
5) Energy Efficiency
An electrical appliance like a ceiling fan must be energy efficient as it is to be operated for a large part of a typical 24-hour day. An energy efficient fan, having energy star rating, is 20% more efficient than a regular one. Suppose you have a large home office and you are planning to install two-three ceiling fans for home office. Now, these fans would remain operational for a greater part of the day. If they are energy efficient, they will save you a considerable amount in a month; and, even more in a year. So, don’t hesitate to spend a little more initially on such energy efficient home appliances as they prove quite economical in the long run.
If you keep the above important points in mind when the next time you visit the market to buy a ceiling fan(s) for your home and/or office, you would certainly pick a value for money appliance.
