A Dyson fan heater uses more electricity in heat mode than it does in other functions, but it does not use more power than an average space heater.
Dyson fan heaters have sleek designs and an abundance of operational modes and features to justify the higher price point that the brand asks for their products.
Although the Dyson fan heater models do move between cooling, heating, and purifying your space, their power usage is not higher than a normal space heater would be.
The heat mode uses the biggest amount of power, but it will not cost you more in electricity than a different space heater would, because of its energy-efficient features.
Is the Dyson fan heater worth the money?
Since the first Air Multiplier technology was used by the brand in 2009, Dyson has been manufacturing a whole range of premium innovative products and have now introduced a fan that will cool you down in the summer and function as a space heater in the winter.
This bladeless, hidden, heating-element design makes the Dyson fan heater much safer to use and convenient to clean.
There are also other features, such as a magnetic remote-control caddy and automatic shut-off, for if the fan is knocked over. This may help justify the premium price tag for the Dyson fan heater.
How much electricity does a Dyson fan heater use?
Since the Dyson fan heater models, such as the HP04, HP01 and HP02 and more, have so many functions, such as heating, cooling, and purifying, it is obvious that these fans will need a considerable amount of power to do what they do.
These fan heaters can heat a room of up to 999 square feet to about 99 degrees Fahrenheit, in an even and controlled manner.
Given that these Dyson fan heaters can cost between $594.99 and $735, it is important to know whether a high electricity bill as you continuously use your Dyson fan heater, will add to this initial high initial cost.
All of the above models, and newer fan heater models, such as the AM09, use about 1500 to 2000 Watts at the maximum when they are running in heat mode.
This is similar to other space heater models and considering that this fan heater has so many other features that use less power, it will not end up costing you more than running any other heater would in the long run.
If you are concerned about energy usage, it is important to understand that Dyson has included many features to try and make their fan heaters as energy-efficient as possible.
How the Dyson heater fans power usage compares to other space heaters
Although Dyson fan heaters may seem like they use a lot of power in heat mode, compared to the other operational modes, they do consume about the same amount of power as regular space heaters, as demonstrated in the examples below:
| Heater model | Purchase price | Heating capacity | Wattage (in Watts) |
| The Dyson fan heaters (HP04, HP01, and HP02 and AM09 models) | $594.99 to $735 | Ideal for a regular bedroom or office space | About 1500 W |
| Aikoper Store Space Heater | $29.99 | Ideal for a regular bedroom or office space | 1500 W |
| GiveBest Portable Electric Space Heater | $35.99 | Ideal for bedrooms, living rooms, and office spaces | 750 W to 1500 W |
| Dr Infrared Portable Space Heater | $129.99 | Ideal for larger rooms | 1500 W |
How the heating mode of Dyson fan heaters compares to other modes
The factor that usually makes consumers concerned about high power usage when it comes to the Dyson heater fans is the fact that the heating mode uses up to 30 percent more power than the purifying and other operational modes, which can be summarised as follows:
| Operational mode | Power usage |
| Heat | 1500 W |
| Fan | 30 W |
| Standby | 1.39 W |
| Purifier | 36 to 44 W |
Although the power usage in heat mode seems high compared to other operational modes, it is still aligned with other space heaters, as explained above, and Dyson has incorporated several features to keep this as low as possible.

Dyson fan heater features that keep power consumption low
Dyson fan heaters have a sleep mode function, which allows the fan to operate quietly and just as much as it needs to in order to keep your room at the desired temperature.
You can also control the settings from the Dyson mobile application, which gives you greater control over the temperature of your space and your power usage.
