Dyson Hot+Cool HF1
#15 in Fan heatersFull review
For someone who wants one good-looking bladeless unit that heats in winter and cools in summer, and will pay for that. As a heater alone, it is poor value.

De'Longhi SlimStyle HCX9115E
#36 in Fan heatersFull review
For a living room or bedroom where a slim panel looks better than a tower and a set temperature matters. The fans make it quicker than an oil radiator but not silent.
