Dyson Unveils Revolutionary Fan Heater Innovation

Conventional heaters have limited settings; like a watched pot that never boils, they can’t always heat a whole room quickly. And central heating is sometimes wasted on the whole house.

Engineered to heat an entire room, Dyson will launch its fan heater, Dyson Hot, in New Zealand in April 2012.

Watch a video explaining the new Dyson 'Hot Fan'. 

Dyson Hot fan heater can be set between 1 and 37 degrees celsius to heat a room. When it hits the desired temperature, it monitors the room temperature by measuring surrounding air. If a drop is detected, the heater turns back on to maintain the set temperature.

James Dyson says: “Other fan heaters rely on inefficient motors or dust friendly grills. As the heat rises you’re left with a partially heated room and a worrying burning smell. Dyson engineers have developed a heater that produces no smell and heats the whole room”.

It took a team of 22 engineers - including experts in thermo dynamics and fluid mechanics - over three years researching, developing and testing Dyson’s patented Air Multiplier technology for its application in a heater.

How it Works

Using patented Air Multiplier technology, air is drawn in through a mixed flow impeller, a combination of the technologies used in turbochargers and jet engines. It is then accelerated through a 2.5mm aperture (approximately the thickness of a $2 coin) 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, amplifying it six times in a process known as inducement and entrainment.


Low surface temperatures throughout and no visible heating elements.  If tipped over, the machine has been engineered to automatically cut out.

Remote Control

Turning the Dyson Hot fan heater on and off, adjusting temperature, airflow rate and controlling oscillation can be done easily from across a room. The remote control is curved and magnetised to store neatly on top of the machine.


Dyson Hot fan heater has temperature controls and an intelligent thermostat. Variable airflow and oscillation is controlled either by remote or on the front of the machine.

Cooling Fan

Unlike conventional heaters it has a dual-mode function as a cooling fan. In keeping with Dyson’s Air Multiplier range it couples high airflow and velocity.


  • Colour - The Dyson Hot will be available in iron/blue and white/silver
  • Easy to clean – quickly wiped clean with a cloth
  • Weight – approx. 2.57kg
  • Guarantee - Dyson Hot fan heater has been tested for the equivalent of 10 years of constant use and comes with a two year parts and labour guarantee
  • Patents - Currently, worldwide there are over 170 patents and over 270 pending patent applications relating to 21 different technical aspects of the Dyson fan range
  • Environmental chamber - The temperature range in the chambers is from 5°C to 80°C, and 10% relative humidity to 80%
  • Materials – Dyson Hot fan heater is constructed from tough Acrylontride butadiene styrene – ABS. ABS is a tough thermoplastic used to make light, rigid and moulded products. It has good shock absorbing properties and is used to make car bumpers, crash helmets and modern golf club heads. It’s used in Dyson vacuum cleaners and Dyson Airblade hand dryers too.
