energy costs of portable fans

How much electricity does a portable fan use?

Fact Checked Fact Checked

In this Canstar Blue guide, we investigate the hourly running costs of using a portable fan in your home. We look at pedestal, tower and desk fan running costs.

Pedestal, tower and desk fans provide affordable cooling solutions that are great for small spaces. These fans are convenient, portable and use negligible amounts of electricity compared to air conditioners. In this article, Canstar Blue looks at the running costs of these kinds of fans to help you manage your summer power bills.

How much does it cost to use a pedestal fan?

According to Canstar Blue data, a residential pedestal fan will cost anywhere between 1.15c and 2.30c per hour to run, or around $16.79 to $33.58 per year, given the assumptions in the table below. Pedestal fan power outputs vary considerably across different models. Most residential pedestal fans will have a maximum output (measured in watts) of 45W to 75W, but larger commercial pedestal fans may have outputs up to 300W.

The cost of using a pedestal fan will depend on the speed setting of your fan as well as its wattage. It will also of course depend on the rate you pay for electricity. In the below example, we have used a 3-speed pedestal fan with a maximum output of 70W.

Average electricity usage rates are based on single rate, non-solar only plans on Canstar’s database, available for an annual usage of 4,347 kWh. *Assumes fan is used 4 hours per day, 365 days per year.

Modern ceiling fans generally consume less electricity than pedestal fans. That’s because while ceiling fans are larger, pedestal fans oscillate and must spin at a faster rate to create airflow. While a ceiling fans might save you a small portion in electricity, pedestal fans are a lot cheaper to purchase and it doesn’t require any professional installation.

How much does it cost to use a tower fan?

tower-fanAccording to Canstar Blue data, a standard tower fan uses around 100W of electricity which can cost up to 3.28c per hour to run, depending on your circumstances and settings used. Where pedestal fans blow air in a focused circular area, tower fans use several small, vertically aligned fans to create a column of air flow. This means a tower fan usually consumes more electricity than a pedestal fan.

The below table uses a 3-setting tower fan with a maximum output of 100W.

How much does it cost to use a desk fan?

Desk fans are small and are ideal for cooling a single person. As a desk fan is designed to sit close to you, it has a much lower max power output of around 25W to 35W.

To keep things simple, we will again assume this desk fan has three settings and that it has a 30W maximum output.

High 30W 0.98c $14.31

Desk fans are clearly the cheapest type of fan to operate, but it is not suitable for cooling rooms. That means it doesn’t serve as a viable alternative to tower, pedestal or ceiling fans.
