Dyson Hot fan heater

Dyson Hot, heated in style

Goodbye, cold corners. Hello, Hot 

Conventional heaters have limited settings. Like a watched pot that never boils, they can’t always heat a whole room quickly. Meanwhile, central heating is wasted on the whole house when you need heat only one room. Enter the Dyson Hot, a radically different fan heater that’s engineered to warm the whole room – and do it faster.

You can set the temperature at anything from zero to 37 degrees, and the Dyson Hot’s “intelligent” thermostat will keep it there. The heater monitors the room temperature by measuring the surrounding air; if a drop is detected, it turns back on. Says inventor James Dyson: “Fan heaters rely on inefficient motors or dust-friendly grilles. As the heat rises, you’re left with a partially heated room and a worrying burning smell. We’ve developed a heater that heats the whole room, without you having to constantly adjust the temperature.”

It took 22 engineers – including experts in thermodynamics and fluid mechanics – over three years to research, develop and test Dyson’s Air Multiplier technology for its application in a heater. Here’s how it works: 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 2,5 mm aperture set within the loop amplifier. This creates a jet of hot air that passes over an airfoilshaped ramp that channels its direction. Surrounding air is drawn into the airflow, amplifying it six times in a process known as inducement and entrainment.

It’s probably the safest fan heater you can buy – and the most expensive (it sells in the UK for the equivalent of about
R3 400). The Dyson Hot has no visible heating elements, and its casing won’t burn you. If it’s tipped over, the machine will automatically switch off. If you’re feeling lazy, you can use the remote control to turn the heater on or off, adjust the
temperature, airflow rate and oscillation.

Sadly, the heater is not available in this country, although Dyson’s iconic (and equally original) vacuum cleaner is catching on rapidly among well-heeled South African householders who appreciate good design.
