Dyson Hot™ AM04 Fan Heater, Blue

Never knowingly undersold

Product information

The new Dyson Hot™ fan heater looks very different to conventional fan heaters, and it works very differently too.

Rather than fast spinning blades, it uses Dyson’s patented Air Multiplier™ technology to project heat further. This works by drawing in air at the base of the heater by an energy-efficient motor, and using a combination of technologies used in turbochargers and jet engines to generate a powerful airflow.

Air behind and around the machine is amplified 6 times, by being drawn into the airflow through physical processes called inducement and entrainment. Precision is easy to achieve - you can select your target temperature to the degree, and the intelligent thermostat will keep it there. Furthermore, the machine oscillates smoothly to distribute heat across the whole room.

And because there are no blades or visible heating elements, there’s no need for a safety grill. This has the added advantage of making the AM04 easy to clean – simply wipe with a cloth.

Key benefits of the Dyson Hot™ fan heater include:

  • Air Multiplier™ technology – draws in surrounding air to heat the whole room evenly
  • Long-range heat projection – feel direct heat throughout the room
  • Safety features – tip-over automatic cut-out and no visible heating elements
  • Precise – select your target temperature to the degree
  • No worrying burning smell – ceramic plates never exceed 200°C so dust doesn’t burn
  • Cooling fan – high airflow velocity cools you with an uninterrupted stream of smooth air
  • Whole room heat distribution – oscillates smoothly to distribute heat across the whole room
  • Touch-tilt – pivots on its own centre of gravity, staying put without clamping
  • Remote control – push button to quickly adjust temperature, airflow speed and oscillation

For complete peace of mind, the Dyson Hot™ fan heater includes a free 2 year guarantee covering parts and labour.
