Dyson Hot Fan Heater Announced

The launch of a new Dyson product is always something which excites the inner child in you. You hope for something magical, something that will change your life, but you usually end up with a fan of some sort.

And so it was at the latest worldwide launch in London today when the company launched the Dyson Hot, a fan heater which like its predecessor, the Air Multiplier, has no blades.

Dyson claims the Dyson Hot will heat a room evenly faster than any other fan currently available and while we have yet to test out its claim, going on previous experience we have to give Dyson the benefit of the doubt.

The whole thing works in a similar way to the Air Multiplier, but Dyson was at pains to point out that heating a room and cooling a person were two very different propositions.

Using the Air Multiplier technology, air is drawn in through a "mixed flow" impeller which Dyson grandly claims is a combination of the technologies used in turbochargers and jet engines. It is then accelerated through a 2.5mm gap, set within the loop amplifier.

This creates a jet of hot air which passes over an airfoil-shaped ramp channelling its direction. Surrounding air is drawn into the airflow, seemingly amplifying it six times in a process known as "inducement and entrainment" - which sounds like some form of torture to us. The six time amplification compares to a 14x amplification seen on the Air Multiplier fan, a reduction presumably down to the fact that a higher ratio would cool the air too much.

Like its predecessor, the Dyson Hot can rotate through 90 degrees to spread the hot air around and can be set to temperatures between one and 37 degrees. The Dyson Hot will regulate itself so as to maintain the desired temperature rather than constantly pumping out hot air. As well as helping save energy, it will make your living conditions a lot more comfortable.

Safety is a major issue with fan heaters and Dyson were very conscious of this. The body of the heater does not get hot to the touch and the two ceramic stone elements are hidden within the sides of the fan so as to prevent the exterior heating up. The fan is also fitted with a switch so that if it falls over it will cut out.

Another issue with traditional fan heaters, according to Dyson, is that they heat up so much they burn the dust in the air around them, creating a nasty smell. The ceramic stones are calibrated so that they won't get hot enough to burn this dust, thus eliminating the problem.

The controls on the front of the Dyson Hot are straight forward, allowing you to turn it on/off, control the rotation, set the temperature and set the air flow level as well as see what temperature the fan is set at. A neat remote control replicates these functions.

Because the temperature can be set as low as one degree, the Dyson Hot can also be used as a regular fan to cool a room, though Dyson pointed out that this was not its primary function and would not replace the Air Multiplier range.

The Dyson Hot will be available in iron/blue and white/silver and will set you back £269.99 when it goes on sale later today in John Lewis and from other retailers at the beginning of October.

While we were hoping for a cyclone-powered PC or a smartphone that ran on air, we'll have to make do with a fan heater which Dyson claims could eventually replace your central heating system.

Fantastic kit, but insane price for what it is.

Shame there's no Samsung around to copy these things.

Yeah, what should happen is that Dyson(A British Company) should spend 3 years developing new products, and then in an ideal world Samsung(A Korean Company) should then blatantly copy the ideas to reap the benefits. Who needs British jobs anyway, it's much better if UK people just keep getting into debt and buy cheap foreign goods. It's like Apple & HTC/Samsung etc, in an ideal world Apple should continue spending $millions on R&D, and then for the benefit of mankind East Asia company's should photocopy the ideas, it helps keep there R&D costs down after all, just seems fair to me really.

Using electric power may be the most inefficient and expensive method of heating. Even more inefficient is heating by air stream, because the flow of air over the skin cooles it down (the chill effect). To the contrary, electric heating by infrared radiation is the most efficient within this end energy, because the skin as temperature sensor is directly heated up and less so the air and the walls around the inhabitant.

However, the resulting temperature increase of the heated room does not depend from the method with which the energy is dissipated in a room! If it were not so, we could bake with this heater or we would wait for the Dyson electric oven.

But if it turns out that the Dyson heater is by some way able to increase the temperature felt by the consumer by 20% or so, and if he consumes power for 100 £ a year, it means that the cost of this Dyson will be amortised within 3 years only.

I have tryed the Dyson heater and was terribly disappointed by it. It was loud (same complaints I have heard about their fan), and the heating output was quite low as well. Had to sit directly in front of it to feel the warmth, was enough heating only a smaller room like bedroom, and couldnt handle living room. Sent back for refunds and bought a Bionaire BH3950 ( http://electric-heaters-review.com/bionaire-bh3950-micathermic-element-console-heater-review ). I know this is different category but is way cheaper than the dyson heater and also good at heating, not just in looking good.
