Dyson Hot+Cool Jet Focus Fan Heater is a home heating and cooling appliance that uses amplified airflow and targeted control to warm or cool rooms. Responsive temperature control and selectable airflow modes make life easier on changeable days. Is the combined heating and cooling performance a better choice than separate appliances?

⚡ At a Glance
  • Airflow Performance: Amplified smooth stream projects uninterrupted air across a room
  • Best for: Homes needing rapid heating and occasional targeted cooling
  • Not ideal for: Rooms requiring a permanently installed fixed heating solution

Air Multiplier technology amplifies surrounding air to project a powerful, uninterrupted stream. PTC ceramic plates warm quickly while an intelligent thermostat maintains the chosen temperature.


Quick, even warming – Thanks to PTC ceramic plates

PTC ceramic plates heat up rapidly and transfer heat into the passing airflow so warmth is carried into the room. The plates work with amplified airflow to reduce hotspots and spread heat more uniformly.

Faster arrival of comfortable warmth, with temperatures distributed more evenly around the room rather than concentrated close to the unit.

Strong, smooth cooling – With Air Multiplier technology

Air Multiplier technology draws in surrounding air and amplifies it to create a continuous, uninterrupted stream of smooth airflow. The amplified stream produces a stronger cooling effect than a simple fan blade design.

Direct cooling or a gentle breeze cools occupants quickly, making the unit useful on warm days as well as cold ones.

Targeted or whole-room control – With Jet Focus control and intelligent thermostat

Jet Focus control switches between Focused and Diffused airflow modes for a concentrated stream or wider circulation. An intelligent thermostat maintains the set room temperature to avoid frequent manual adjustments.

Choose a precise, concentrated airflow for personal use or a diffuse setting to warm a whole room while the thermostat keeps temperatures steady.

✨ The 4 Key Reasons for Dyson Hot+Cool Jet Focus Fan Heater
  1. Two-in-one heating and cooling – Switches between warming and cooling for year-round comfort
  2. Jet Focus control – Choose focused stream or diffused flow for flexible warming
  3. Intelligent thermostat – Maintains a chosen room temperature without constant adjustment
  4. Fast PTC ceramic heating – Heats up swiftly to reduce waiting for warmth
