Dyson AM09 Fan Heater, White/Silver

Product Information

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.

Handheld Vacuums – these are powerful vacuums but light as well cord-free to clean anywhere from the home to the car. You could pay hundreds of pounds over the odds if you buy a Dyson vacuum at the wrong time or from the wrong place.

The fan and heater are controlled by a remote that magnetically attaches to the top of the unit. The remote was useful for changing the setting of the fan without moving from our seats, but it is the only way to control several features of the fan, so make sure you don’t lose it. Oscillation is one of the remote-controlled features and one of our favorites. The fan moves quietly along a wide arc, delivering a blast of warm air across the length of a room. It also tilts up and down so you can direct the airflow right where you need it. 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. It's also worth remembering that having multiple accessories can be more of a hindrance than a help, especially when storing them, which is another reason not to splash out on a model with expensive extras unless you're sure you need them. You want to get hot, or stay cool? As a two-in one device, the AM09 has you covered whether it’s the deepest darkest nights of winter, or a sweltering summer’s day. As a fan heater, it can pump out either fast blasts of cooling air, or warm cosy waves.

Refurbished handheld and cordless vacuums, fans, heaters and humidifiers are guaranteed for one year. 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. 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.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. The 3-metre power cord shouldn’t cause you an problems when it comes to plug placement, either – I found this afforded enough freedom to place the fan in any discreet but efficient location. Other Things to Consider There are some brilliant Dyson vacuums out there, but we've also found worthy alternatives from other brands, including much cheaper options. 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.
