Recession Heating - Is New Dyson Hot The Answer?

To be more accurate,

It is not a fan heater because it does not have a fan! :cool:

Then why in their brochure is it called a Dyson Hot fan heater

No idea. Perhaps you should have him up on the Trade Descriptions Act? :rotfl:

Interesting that Dyson choose not to state the power rating of their heater in their literature.
The prices being banded about are from the Dyson website.

-Yeah, it is interesting. Not surprising though. The market he's chasing are unlikely to have done a home survey and come to the conclusion they need a heater with a capability of 1.5kW (for example). The market probably wouldn't know a kW from a black pudding, but they sure know the price tag and shape are impressive.

Nothing new in the PTC metal/ceramic heater core - my car has them for the cabin heater - probably lowers the manufacturing cost.

The heater is style over substance. It's the way of the world these days. I have no problem at all at people's choice of paying £300 (or £299.99 or £240) for the style - it's just misleading if the sales pitch makes out you are getting some substance too. Poor Mr Dyson has great difficulty in keeping honest in his adverts - it causes them to be full of meaningless gobbldegook, which I guess isn't misleading, but I bet his engineering head wonders at the advert content.

Can't be! If it was it would be pedants' day.

Perhaps it's a heater only for Dyson fans?

Perhaps you should take action under the Trade Descriptions Act - he misled you - not me!

Mind you marketing an appliance as a fan heater, and discovering it has a fan, might make any complaint on those grounds seem a little odd.

Given the new evidence of discount pricing I have revised my initial calculations. For the price of 2 of these heaters an average household could pay their electricity bill for 18 months. A billy bargain. Not.

I went into great detail a few days ago when you said the same thing, and you didn't reply to my correction of your views.

Because without giving a course in quantum mechanics it will just go round in circles. And we are talking about a very small number, so small a 8-bit calculator will still say 100% due to rounding errors but it is still not correct in terms of .

You're (still) arguing against well known laws of thermodynamics which have been accepted for hundreds of years - they aren't really posters opinions, they are scientific laws.

Yes, when Kelvin aid they just needed to get the significant figures in 1900! Since then Newtonian physics has been proven to be increasingly a generalisation.

When I quoted phase change you replied that was only in change of phase from one state to another (Solid/liquid/gas/plasma)....
I was talking about Phase change in Hilbert space due to the changing of wavelengths....

Indeed most of this centres around the wave function ... and for want of a better source...

http://en.wikipedia.org/wiki/Wave_functions
"The wave function is central to quantum mechanics, because it is a fundamental postulate of quantum mechanics. It is the source of the mysterious consequences and philosophical difficulties in the interpretations of quantum mechanics—topics that continue to be debated even today."

I've no idea what black body radiators have to do with this discussion.

That's why I don't want to go into it.....

Steve-L,

Please don't insult our inteligence by coming out with bul***** -

Your post#11 about fans reducing efficiency of a heater, halogen heaters and black body etc, was just nonsense and demonstrated physics is just not your field.

Surely enough people have pointed that out to you.
