When ceiling fans are directly compared to air conditioners, the savings and other advantages offered are greater than many people imagine. The following is a comparison of the two and offers smart advice on how to get the most out of ceiling fans.
A good fan will only consume around a tenth of the energy as a typical medium-sized air-conditioning unit. This is because ceiling fans work on a different principle than air conditioning. Instead of actually lowering the temperature of the air with compressors, they provide a cool breeze that evaporates moisture from the skin and makes those exposed to it feel much cooler on warm days (and this allows windows to be kept open).
In the winter, by reversing the direction of rotation of the blades, they can be made to pull cool air up and push warm air (which naturally rises to the ceiling) down and create a comfortable distribution of heat. This makes ceiling fans a versatile all-year appliance for the home and office. While a ceiling fan may not be able to totally eliminate the need for air conditioning or heating, it can reduce the frequency in which it is necessary to artificially heat or cool air. In addition, when ceiling fans are used in conjunction with heating or air conditioning, they can still increase energy efficiency by making it possible to set other appliances at lower settings in which they are not using as much power.
Ceiling fans last longer than air conditioner units and require little maintenance, while there are many potential maintenance problems which can arise with air conditioner units. Ceiling fans are proven to be more durable than ac units have over the years for numerous reasons to include the simplicity of their design. With air conditioners costing more, breaking down faster and being more expensive to run than ceiling fans, they are certainly far less economical.
Even air distribution
AC units do not distribute air evenly within rooms due to the air only being dispensed through small vents in one area. Ceiling fans have the large blades, which rotate and guarantee even distribution of cooler air. Placed on ceilings of rooms, they are ideal for ventilation.
Ceiling fans are more versatile than air conditioners. Anywhere there is a ceiling it is possible to install a fan. Air conditioners do not have the same versatility and must have an outside connection.
Silence is golden
Ceiling fans with properly balanced blades are quieter than air conditioners. Air conditioners are far louder and should not be placed close to a sleeping person for noise as well as health reasons.
Better physical as well as financial health
Air conditioners have health issues that ceiling fans do not. Excessive use of air conditioners can aggravate conditions like arthritis and neuritis as well as sinus trouble. They also make people much more susceptible to colds. Furthermore, extreme variances between inside and outside air can make people sick. Finally, there are the micro-organisms that are often found in air-conditioning units that can cause breathing problems.
Making the most of ceiling fans
The following will make it possible to get maximum savings.
Knowing what to get
With so many factors to choose from that can affect energy efficiency of a ceiling fan in different ways, it can be very difficult to know what to get. To help sort it all out, consumers can look for the Energy Star logo. This program, adopted in various countries, gives the Energy Star logo to products that meet energy efficiency guidelines. Ceiling fans with this logo are generally at least 50% more energy efficient than fans without.
A major influence on the energy efficiency of ceiling fans is maintenance. Excessive dirt and dust can affect the motor’ s performance and force it to use more power than necessary. In addition, if the fan wobbles for some reason, be it loose fittings or other factors, the extra stress on the motor will make the fan less efficient. This is why it is important for people to maintain their ceiling fans and make sure that they are in tip-top condition.
Energy efficient ceiling fans need to have sufficient blade angles. If the blades are not set at great enough angles, they will simply spin around without moving much air. On the other hand, too much of a blade angle will put undue stress on the fan and lower efficiency. Generally, around 13 degrees is a good blade angle for a ceiling fan.
Size and efficiency
While a smaller fan will use less energy, one that is too small will not provide the cooling effect needed. On the other hand, one that is larger than the room requires will consume more power than is needed for the desired effect. Therefore, it is necessary to find the sweet spot and get a fan that is large enough, but not too large, for the room. For rooms up 75 square feet or less, fans with blades up to 36 inches are a good size. Medium sized fans with 36 to 44-inch blades should be used in rooms from 76 to 145 square feet. For rooms over 145 square feet, blades of 45 inches or more are appropriate.
Of course, the most energy efficient fans are those that are not running. Forming good habits of always turning off the fan and lights when leaving a room will further increase the financial and environmental benefits of using them.
People who would like to save both energy and money should keep these factors in mind and use them as a guide. A properly maintained ceiling fan will offer great savings over an AC unit.
