Using Dyson’s unique Air Multiplier technology combined with variable oscillation up to an impressive 350 degrees, the Hot+Cool delivers a good wallop of warmth. According to the company, this heater will provide full coverage in rooms up to 81m³. As well as a built-in thermostat, air flow can be altered using the included magnetic remote control or, if you prefer, via Dyson’s excellent app. If you’re in the market for a saviour against the cold that’s easy to store away when not in use, then this dinky unit is most definitely worth the small outlay. Whether you want to heat a chilly home office or just take the edge off when the temperatures plummet, a fan heater is a great option for short-term use. Rather than heat your entire home, electric fan heaters can be placed in your immediate vicinity, directing heat to where it’s needed most. Simply place the heater a few metres away from where you’re sitting and your feet, hands and face will remain warm while you watch TV, read a book, cook or work at your desktop.

It comes with two simple controls: a thermostat dial and another for its three heat settings (up to an impressive 2.4kW). The highest heat setting also increases the fan’s speed for extra reach. This attractive Italian-designed model from DeLonghi arrives with a high-quality, cool-to-the-touch metal casing with legs attached. And with its maximum sound pressure of 48dB, it’s one of the quietest fan heaters you can buy.
