Do not be fooled - this is a very expensive gimmick.,
For all of you that are ready to be fooled by this new high tech product, I make the following comments.
At 2.0 kW max output, the heater OUTPUT is the same as ANY electric heater rated at 2.0 kW.
As electric heat is 100% efficient (there are no system external losses), it can only add 2.0 kW of actual HEAT into your room.
In doing so it uses 2.0 kWh which is added onto your meter and your electric bill (at about 10p per kWh) - THE OPERATING COST WILL BE THE SAME AS ANY OTHER 2.0 kW DOMESTIC ELECTRIC FAN HEATER.
Some of the '5 star' reviews are based on the Dyson heater being able to heat their room 'super' fast, as if this is somehow attributed to DYSON's 'special' design. This is not the case. ANY cheap fan heater of the same power rating will have an IDENTICAL effect on your room temperature.
I would suggest trying a cheaper £30.00 heater first (also available on AMAZON). You will get the exactly the same result and save yourself nearly £250.00.
Okay it may blow air around, but it WILL NOT not heat the room any faster.
It can't and won't miraculously add any 'free' heat to your room.
It may circulate the air around the room to create an even temperature - but so does ANY fan heater.
Any heat that is created by so called 'inefficient' motors used in more conventional fan heaters, also ends up in your room, so as there are no 'external' losses there is absolutely no difference to overall efficiency. The fan motor power is normally very small when compared to the heater power anyway.
Also, regarding the claimed 'POWERFUL COOLING' (I assume in fan only mode).
This is MISLEADING and simply NOT TRUE. NO FAN cools simply by moving air through itself.
There is NO removal of heat from the air.
The air temperature out of the fan is the same as the air temperature into the fan.
IT CANNOT AND WILL NOT LOWER YOUR ROOM TEMPERATURE and therefore it DOES NOT COOL.
However, if YOU sit with the air blowing at YOU then you will feel cooler.
A fan moves air across your skin which causes faster evaporation of 'moisture' (sweat), which then cools you (latent heat of evaporation).
The faster the air velocity, the faster the evaporation, the more 'latent heat' is adsorbed, the cooler you feel.
If you don't believe me, measure the inlet and outlet air temperatures through any room fan (or the DYSON) - they are equal.
THIS IS A VERY, VERY, EXPENSIVE GIMMICK (ORNAMENT), SO DO NOT BE FOOLED BY TECHNICAL B.S. OR MISLEADING CLAIMS.
UNLESS YOU HAVE MONEY TO THROW AWAY PLEASE CHECK THIS OUT THOROUGHLY BEFORE BUYING.
