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.

Quickly warms - or cools - a room; Looks great; Safe design

Expensive; Noisy at top levels; Remote essential

Good. But once switched on, the power supply takes a hit and everything (all lighting fixtures) in the room literally dims.

I thought this would be useful in cold weather but when you set the temperature the fan heats up and then stops. The machine then releases a cold draught, cooling the ambient air. Tried to get our money back but we have had it more than 35 days and Dyson say this is how the machine is designed.

light,easy to adjust .powerful heating

Dyson's brand new Hot + Cool AM09 bladeless fan heater has come at quite the right time. In typical fashion, the British weather can't make it's mind up at the moment, making one day blazing hot, while another could be as cold as ice, and as a result, Dyson thinks it's got your back with its latest...

The Dyson AM09 is the latest 'Hot + Cool' air multiplier fan-turn-heater from the vacuum cleaner specialist. It introduces what Dyson calls Jet Focus, which adds a second airflow aperture ring that pushes air out in a narrower, more precise way.

This machine was sent to me following a two year try with the AM05. The AM05 would work for a bit and then quit. This machine is wonderful and I thank the customer service department for being so kind and understanding and for making sure I had a machine that worked!
