British industrial design brand Dyson have unveiled their latest product: a fan heater.

Yes, it looks a lot like the Air Multiplier bladeless fans released last year and it incorporates the same technology, channelling the air through a 2.5mm ring-shaped aperture and accelerating it over an aerofoil.

The Dyson Hot has low surface temperatures and no grilles to attract dust, incorporating an automatic thermostat and a magnetic remote control that fits over the top of the machine.

It can also be used without the heating element as a cooling fan.

James Dyson is famous for inventing vacuum cleaners without dust bags and released his first fans without blades in 2009. Listen to our podcast interview with James Dyson here.

Here are some more details from Dyson:

Goodbye cold corners. Hello Hot.

Dyson Hot™ fan heater warms up every part of the room – fast

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 the room, Dyson Hot™ fan heater is the fastest to heat the room evenly.

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 (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 6 times in a process known as inducement and entrainment.

Safety: Low surface temperatures throughout and no visible heating elements. And 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.

Precision: 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.
