The Dyson AM09 Hot & Cool? Fan Heater is a powerful, effective heater in the winter and a quiet cooling fan in the summer. Dyson's patented Air Multiplier? technology draws air in which is heated over ceramic plates before being projected forward for long-range, full room heat.

A combination heater/fan can be used all year long; Pleasant; modern aesthetics are appealing to most people; A variety of heat patterns and oscillation help with heat distribution; Housing is cool to the touch

Not that impressed, will wait till it gets hot this week, but my high velocity floor fan from Kmart for $40 has more power and coolness than this very expensive Dyson, maybe coming back for refund. My toaster I bought at the same time is awesome. Very happy with that but think the Dyson maybe a dud.

Dyson's fan line has impressed ever since it first entered homes, safely removing the dangerous blades of traditional fans in favor of Dyson's smart bladeless air multiplier technology.

I bought this to help in the heatwave and was very pleased with the way it cooled the room quickly and quietly.

Second purchase of a Dyson AM09 fan heater, this time for the office. Bought with a discount during the Black Friday promotional time and am very happy with it. Works exactly as expected, warms without drying the air, much better than the previous heater and with the thermostat and heat setting will...

I live in Victorian house, every room with air conditioning, ok summer Dyson can compete, but in winder heats up quicker and cheaper than an expensive Dacon air conditioning unit.

Not had it long, but so far so good. We bought it mainly as a cooler for our bedroom. It works well. It brings down the temperature and makes the room much more comfortable. As a heater it is excellent. Hardly any noise and the thermostat works well. The remote control is easy to use.

This is a very expensive talking point rather than an effective hot or cool fan. It looks great and has the Dyson name so people think it must be good but its no more effective than most other products available.

"This product looks very good but to be honest I was expecting a lot more for the price. I have it in a treatment room at my salon and its cool but not as cold as I hoped. I expected a little more from dyson technology as I love their products normally; hgowever a cheaper fan would have the same...
