The Dyson NOT so Hot Heater
By CC
I bought my Dyson Hot heater for one simple reason, curiosity.
The Dyson sounded promising and made the pitch that it was something truly new and revolutionary so I bit and got one....a white one!

At first glance the quality looked good, fit and finish were tight and it looked good on the surface.

Sitting down, I kicked back and prepared to enjoy reading the manual....that was short lived as it had lots of information on warranty and legal guck and only the most basic of operation information with absolutely no information showing specifications, no power use...no Heat output....nothing

Moving on I plugged it into the power use tester to see how much power it would consume and in return how much heat it put out at 12 inches away.

Power use was high especially considering how low the temperature it was putting out, for example of the ten temp ranges (here are three examples): Level 1: 1207 watts @ 102 degrees ambient at 12 inches...Level 5: 1280 watts @ 108 degrees at 12 inches ambient and Level 10: 1391 watts @ 105 degrees at 12 inches ambient...I can rub my hands together and get higher temps, these are dismally low numbers when compare to my 5 year old HOTBLAST Ceramic heater that puts out 142 degrees at 24 inches at 750 watts.

True the heater is being touted as SAFE and it is, but it has no more safety features than any $15.00 heater, not even a grounded plug....both have tip over protection and overload protection but claiming to be safe while you sit there freezing as your power meter spins, little conciliation since this is SUPPOSED to be a heater first and foremost not some over priced thing ah ma jig!

Now comes the real fun....in the three weeks I have owned it, from day one the thermostat has been mis-behaving, (dysfunctional). It turns off when it reaches the preset shutoff but between 30 seconds to two minutes later turns right back on and just continues this off and on routine indefinitely or until you manually shut the heater off.
Then there is mis-calibrated thermostat between three to five degrees high when in operation (it says it is 68 degrees when in reality two other thermostats placed right next to the base confirm it is actually only 64.

Dyson's HOT selling points are as follows:

1. Brushless motor (the fan / heater industry has used them for over 20 years)

2. Air Multiplier Technology ( Ducted fans have been used in portable heaters for over 50 years)

3. Long Range heat projection, (this I will agree with, Dyson has figured it out that smooth low pressure air flow is better than high pressure when it comes to heat, the faster it moves the more is dissipates and the more heat is lost, unfortunately the high energy requirement to generate the low heat output from this heater means energy efficiency and heat production is poor at best.

4. Safety features (nothing new here virtually all portable electrics have had tip over and overload protection for the past ten years and this heater also lacks one of the MOST important feature.....a GROUNDED PLUG!)

5. Precise temperature control (a very standard digital temperature control that with the Dyson lacks timed use feature and in my samples case had debilitating issues....see above)

6. No Worry Burning Smell (burning dust odor is typical of the environment it is used in and old wire or nichrome type heaters which have long since been replaced by cheaper aluminum PTC elements, the Dyson does have micro fine air intakes but deep inside it also has a secondary filter that is not easily serviced to stop any dirt from getting into the heating elements from the impeller itself, unfortunately THIS is what will plug and heat output and efficiency will be reduced significantly. Other odors the Dyson Hot WILL pick up because it is made of plastic will be food and environmental odors).

7. High Air Flow Cooling Fan ( because this is a heater the fan velocity has been greatly reduced over the Dyson fan and is simply no better than the fan mode available on 95% of all portable heaters over the past five years)

8. Complete Control with its remote control unit (again, nothing new here as most mid range portable heaters $19.95 and above have them but the Dyson is different in that it is tiny and very easy to loose).

Dyson claims they took three years and 22 engineers to come up with this,if so I seriously want to know where they were educated because in the end the Dyson HOT is simply no better than most $15.00 portable electric heaters when it comes to safe heating.

P.T. Barnum said it best "There is a Sucker Born Every Minute"....or Captain Jack Sparrow "Take what ya can....GIVE NOTHIN' BACK"....that's this heater then there is the salt in the wound, not even made in the UK....made in Malaysia because labor is 30% cheaper!

Sorry Dyson, I had really hoped for just a grain of truth but your product simply does not prove out at many levels...If B.S. were heat, the Dyson HOT could heat the world!

Design has a price
By digitil
This product is amazing. Not as a heater but as a conversation piece and a work of industrial art. You can buy a simple couch at Ikea and it will do just fine or you can buy an expensive Italian sofa for ten times as much and be proud. You can buy a boring but functional suit for 200 bucks or you can get a tailored one for three grand. This heater does what it says and it looks great doing it. My only real gripe is that it can be a bit noisy but not more noisy than a traditional one. And I kind of wish it was ceramic. That would have extra cool factor.
