Dyson AM09 Fan Heater, White/Silver

Product Information

Employing the same engineering brilliance behind their immensely popular vacuum cleaners, the Dyson AM09 Hot & Cool Heater is a stylish and effective domestic fan device that also functions as a standard fan to cool down the air. As a result, it is of use not only in the colder months, but throughout every season in the year. It has a temperature range of 1°C - 37 °C. For heating, a thermostatic system is used and once a room has reached the desired temperature, the AM09 will reduce its output so that it is maintained. When it comes to cooling down a room, the unit does not function as an air conditioner, rather, it blows the air around the room to create a fresh and cooling effect. Dyson AM09 Hot & Cool: Stylish You can lower the desired temperature to as low as one degree, but doing so won’t actually activate the fan; you’ll need to press the cooling button and switch to fan-only mode. Switch from heating mode to cooling and you’ll also get a face full of warm air for roughly thirty seconds before the heating elements cool down and the flow of air drops in temperature. Perhaps more impressively is how the AM09 manages to achieve this while being significantly quieter than the outgoing AM05. The improved motor is barely audible on the lowest heat setting, and only slightly louder on the lowest fan levels. We could comfortably get to sleep with the fan on a medium setting, and it didn’t prove distracting when watching TV or having a conversation during the daytime either. It’s a welcome improvment over the old model and a major selling point for anyone with a loud, traditional fan heater. Robot Vacuums – Dyson robot vacuums have the most powerful suction of any robot vacuum. It includes the patented Dyson cyclone technology, the Dyson digital motor and the 360 degree vision system.

Cylinder Vacuums – the cylinder vacuums of Dyson can remove dust from all sorts of floors and will follow you around your home with greater control. Accessories – Dyson accessories are as sturdy as their vacuums when it comes to removing dust, dirt and allergens. Despite the thermostat being contained in the base of the fan, it was accurate enough to dial down the airflow when the majority of the room had reached the desired temperature. There were a few areas where our thermometer didn’t quite measure the temperature we’d set, but it was still much warmer than ambient. Like on the company’s past air multipliers, a brushless motor and bladeless design combine to ensure airflow is not buffeted. This might not sound like a major advantage, but you won’t want to revert to a choppy, bladed fan once you’ve tried it. It’s an expensive option, but one which gives a luxury performance.

Build quality isn't quite on the level we'd expect for the price, but Dyson's AM09 hot + cool is still the best looking fan heater around

The AM09 looks almost identical to the outgoing AM05, with a tall, oblong-shaped aperture and a chunky base which hides its brushless motor. Dyson has removed almost all of the buttons from the front, replacing them with a single power button and white LCD display showing airflow speed and desired temperature. Without the bundled remote, you’ll only be able to turn the fan on and off, and cycle through target temperatures by holding in the single button on the front of the unit. There’s no option to turn the power and temperature LEDs off, which could be a little irritating if the fan is directly in your line of sight when trying to get to sleep. There is at least a nine hour sleep timer, so you can set it to switch off automatically before you drop off. Models in the same range (eg the V15 Detect range or the V11 range) usually have the same core machine – the only difference is the accessories and supplied floor heads.

Handheld Vacuums – these are powerful vacuums but light as well cord-free to clean anywhere from the home to the car. We love that the cooling and heating buttons allow us to switch between fan mode and heating mode with the touch of a finger. The AM09 isn’t oppressively loud, either. A new aerodynamic diffuser helps cut down on fan noise – it’s considerably quieter than its predecessor. The room filling mode is the noisier of the two modes, but not by much. It depends on the size of your room and the difference between ambient and desired temperatures, but during our testing the AM09 got up to temperature in under five minutes. Of course, at the time of writing in mid-April, the ambient temperature of roughly 20 degrees is a world away from a cold British winter evening, so we’ll have to return to testing later in the year to see whether it maintains these speeds. You would expect the prices of older vacuums to go down rather than up, but we've found that some Dysons end up being sold for a price that well exceeds the original amount – even several years after they were launched.Not surprisingly, the AM09 also earns accolades for its functional design as well. The remote on the Dyson AM09 is conveniently designed, with buttons that are intuitive and easy to press. We love that the cooling and heating buttons allow us to switch between fan mode and heating mode with the touch of a finger. We also appreciate the magnet that holds the remote on the top of the unit. Once you get in the habit of storing it there, it holds securely and will stay there indefinitely. In terms of performance, the V8 is clearly the superior vacuum. The longer battery life and improved bin design make it better suited to thorough cleaning. It has a slightly lower suction power on normal mode, but the V8 engine is more powerful on max mode. V8 models also come with Dyson’s best floor heads for more effective carpet and hard floor cleaning.
