If you are planning to install ceiling fans in your home or business, then you must consider a critical question, how many fans do you need? This is important because fans need power to run and installing too many will lead to wasted power and too few will not provide adequate air circulation. So, an accurate calculation of the required number of fans would help both the environment as well as your finances.
Making An Assessment
It is easy to estimate the number of fans you need for your home. Unless the size of the rooms, or a particular room, is much bigger than average (see the next section in this case), one fan per room is adequate. Installing two fans in such rooms does not increase the flow of air and serves no purpose other than to waste energy.
A commercial area is a different ballgame altogether. If it has a large floor plan, the area definitely needs multiple fans. A good example is a restaurant where the design of the dining area will require multiple fans to keep the patrons cool. A larger warehouse or production factory will also need multiple fans.
How Many Fans Do I Need?
So, after the assessment of the above factors, how many fans do you actually need? For your home, if your rooms are bigger, you will need to think about the size or the area of the room. You will also need to consider the size of the fan to buy.
When you buy a fan from an authorised store, the sales person will be able to give you the information both about the size of the fan as well as the size of the room it will be sufficient for. The marketing/information material available with the fan also mentions the same. However, following are general guidelines that will give you a rough idea of the size of the fan that will work for a particular area:
- Area up to 12 Square Metres: 1067 mm or 42 inches
- Area up to 18 Square Metres: 1200 mm or 48 inches
- Area up to 30 Square Metres: 1300 mm or 52 inches
- Area up to 40 Square Metres: 1400 mm or 56 inches
No matter whether you are looking to install a fan in your home or commercial space, this chart should give you a rough idea of the number of fans you need. From our example of a restaurant above, if the area of the dining location is 160 square metres, you will need 4 fans of 56 inches each.
Another point that needs due consideration is the shape and design of the room as well as the height of the ceiling. This is important to ensure that the flow of the air is adequate. Consult your dealer when making a purchase.
The Right Way to Install Multiple Fans
When you are installing a single fan in your room, it is most often placed in the centre of the ceiling. However, when it is a question of installing multiple ones, making sure the space between them is even is of paramount importance to ensure adequate flow of air. Also, ceiling fans are most effective when you are sitting directly below them. So, the design and seating layout of the area should be such that evenly-spaced ceiling fans are installed directly over main seating areas. Finally, the larger the blades of the fan, more is the area it can cover.
