Fortunately, the small, ergonomic remote that clips to the top of the fan heater’s curved body remains. This makes the remote easier to store, harder to lose.

For pure heating purposes, it's a very good space heater, and a more feature-rich option than something like the Lasko 754200. I also appreciated that, unlike my Lasko heater, it'll automatically shut off if it gets knocked over.

The most striking thing about the design of the Dyson Hot + Cool AM09 is its bladeless cavity. Making up close to two-thirds of the footprint of the device, It’s through this loop that the warm or cool air is propelled

The AM09 has a new trick up its sleeve – the Coandă effect, which bends the airflow around the edge of the loop and out at an angle.

Yes, the controls have been relocated to the handy, compact remote, but the lack of any on-board controls can be frustrating at times.

Misplace the remote (or worse, lose it), and you'll only be able to switch the fan on and off, or hold the power button down to dial the temperature up or down. You won't be able to turn oscillation on, you won't be switch to a more focused stream of air -- you won't even be able to adjust the fan's intensity.

As for how noisy the fan is, that depends on the speed level you’ve got the fan set to. At its top levels, it is indeed notably loud, constantly humming.

The Dyson AM09 Fan Heater is a ceramic heater that we tested against the Lasko 754200 in previous years’ tests, and the Dyson proved weaker than the far, far cheaper model.

The Dyson AM09 costs £400, which is more than 10 times the price of similar oscillating fan heaters, and £150 more than Dyson’s cool-only fan, it's quite expensive.

An Overview On Space Heaters

Being cold is no fun. Whether it’s a spot in your home that the heat just doesn’t reach or an office that stays chilly year-round, sometimes a steady blast of warm air is exactly what you need to be comfortable. Space heaters are great for fulfilling that demand. Simply set one on the floor next to you and enjoy the warmth.

But there are many factors to consider when you’re picking out a space heater. The majority of house fires start because of portable space heaters, so it’s important to choose one with built-in safety features. Look for heaters with auto shut-off and tip protection, especially if you have small children or pets in the house. You should also place your heater away from flammable objects, like drapes and bedding.

Once you’ve squared away safety, you’ll want to look for a space heater that provides the level of warmth you need. Some space heaters are designed to be directional in nature, primarily heating the area where they’re pointed. However, many newer space heaters are less directional, warming an entire area and all the objects within it. If you’re in a cubicle at work, you’ll likely be more interested in heating yourself, whereas at home you may prefer to warm up an entire room.

Portability and size are also important things to consider, especially if you won’t be using your heater in the same space. Some heaters are small and portable, even coming equipped with carrying handles to make them easy to move around. These heaters are also usually smaller in size, making them handy for slipping under your desk to keep your feet warm while you work. Much larger units typically fit better if you’re heating a whole room in your home rather than carrying them back and forth to the office every day.

DYWM Fun Fact

If you’re using a space heater to make up for a chilly office or a part of your home that’s colder than the rest, you probably have no other choice. However, if you’re using a space heater to save money on your utility bill, that may not be such a good idea. Even the most efficient space heater can’t do as well as your central heating when it comes to warming large spaces. According to the U.S. Energy Department, gas furnaces cost 43 percent of what you’d spend to heat the same space with an electric space heater. Dressing in layers or buying an electric blanket could be more affordable alternatives.

The Space Heater Buying Guide

  • If you’re looking for a whole room heater, make sure you get one with a temperature-based thermostat. The Vornado Vortex and Lasko space heaters have setting-based thermostats, which means an adjustment from low to high. With the Vornado Whole Room and Dr. Infrared heaters, you can set a desired temperature, such as 65 or 70 degrees. The units will run until the area achieves that level of warmth, at which point they will shut off.
  • The Vornado Vortex Heater does a better job at heating an individual sitting in front of it than similar heaters that are designed for whole-room heating.
  • Although you’ll always need to exercise caution when operating a space heater, many of today’s models have safety features built in. The Dr. Infrared Heater is certified as safe by the Underwriters Laboratories, with both automatic shut-off and anti-tip over protection. The Lasko Space Heater automatically shuts off if the unit gets too hot, although there is no anti-tip over switch. Both Vornado heaters have anti-tip over features and the Vornado Vortex includes overheat protection.
  • Noise can be a concern, especially if you plan to operate your space heater in the workplace. The Dr. Infrared heater is notably quiet, using its own technology to provide heat at a low speed, which makes it less noisy than comparable space heaters. The Vornado Vortex and Whole Room heaters are also quiet when compared to other space heaters.
  • Size can be an issue, especially if you’re tucking your heater discreetly under a desk. Both Vornado heaters and the Lasko heater are lightweight and portable. The Lasko heater has a handle to make it easy to carry from one space to another. If you plan to mount your space heater on a wall, the Lasko is also a good choice.
  • It’s important to note that the Dr. Infrared heater has been known for thermal fuse failures. However, investing in a high-quality extension cord can keep that from happening, and if it does, the company will ship a new fuse upon request.
