Stay Cool with Fans

Compared to air conditioners, ceiling fans are much more energy-efficient. Air conditioners can consume a large amount of electricity, particularly when operating for long durations, whilst on the other hand, ceiling fans require minimal energy to function, offering a cost-effective cooling alternative.

Did You Know?

Ceiling fans are known to be the most efficient type of fans, as they circulate air effectively within a room, creating a welcomed draft throughout the space?

Ceiling fans can enhance comfort throughout the year with most being fitted with a switch on the side of the fan base for adjusting the direction of the fan blades?

Who knew?!

Why is this important?

By setting the direction of your fan blades, you can regulate the temperature in your home, leading to savings on both cooling and heating expenses.

During summer, run the ceiling fan counterclockwise and in winter, switch the fan to clockwise at a low speed to push warm air from the ceiling down to the living areas.

If you use air conditioning to cool your home, a ceiling fan will allow you to increase the thermostat setting about 2 to 3°C with no reduction in comfort. In temperate climates, or during moderately hot weather, ceiling fans may allow you to avoid using your air conditioner altogether. Install a fan in each room that needs to be cooled during hot weather.

Ceiling fans are only appropriate in rooms with ceilings at least 2.4m high, which is the standard height for most Australian homes. Fans work best when the blades are 2 metres above the floor and 25-30 centimetres (10 to 12 inches) below the ceiling.

Always heed extreme caution in bedrooms that consist of bunk beds or those with a climbing frame. In such cases, a wall fan may be a more suitable option.

Larger ceiling fans can move more air than smaller fans. A 1 metre diameter fan will cool rooms up to 20 square metres, while fans that are 1.3 metres or more should be used in larger rooms. Multiple fans work best in rooms longer than 5.5 metres.

Tip: A larger blade can cool effectively at lower speeds, ideal for areas with potential for disruption by strong breezes. Consider aesthetics when choosing a fan size to avoid overpowering small rooms.

Tip: Cheaper fans can often be a little noisier therefore, consider a more expensive fan for quieter, smoother operation and better reliability. Always check noise ratings and listen to the fan before purchasing.

Tip: When buying ceiling fans, look for the ENERGY STAR® label. Ceiling fans that are Energy Star certified are up to 40% more efficient, on average, than conventional models.

Window Fans

Ever wondered what a window fan is, you’re possible not alone there!

Although not commonly known within Australia, a window fan is a cooling appliance that is mounted on a window frame. They usually have expandable side panels that cover the window completely to facilitate the airflow from it.

The primary benefit of a window fan is that it uses very little energy and can be used to pull in cool, fresh air from the outside or, it can be used to exhaust stale indoor air.

Window fans are perfect for small rooms that tend to get stuffy and humid, but they can also be mounted in windows of large rooms that require greater amount of air circulation and ceiling fans aren’t enough.
