Dyson Hot+Cool HF1

The HF1 is Dyson's current Hot+Cool model (it replaced the older AM09 and reached the UK in late 2025) and it earns its place as the best 2-in-1: it is a genuine heater in winter and a powerful cooling fan in summer, so it earns shelf space all year rather than just in the cold months. It has the most sophisticated controls on this list — 10 fan speeds, oscillation up to 70 degrees, a sleep timer, child lock and full Dyson app integration with scheduling and temperature history. Dyson quotes a sleep-mode noise level of 26dB, though reviewers note it is more audible in heating mode than that figure suggests. The trade-off is stark on value: at an indicative £399.99 RRP it costs several times the Dreo, and as a heater it is best suited to small and medium rooms rather than large open spaces. Buy it for the year-round versatility and design, not because it heats any better per pound than a £70 ceramic heater.
