Dyson AM05 Hot+Cool Fan Heater... Heat an entire room, or cool it down, faster than any other heater or fan we've seen. Just set the target temperature to the degree you want and this awesome product's Air Multiplier technology generates a high-speed jet of warm or cool air to project heat and cold further and faster. Dyson fans and heaters have no blades... instead, they provide a steady stream of smooth cooling or heating air versus spinning blades which usually chop and reduce the amount of preferred (warm or cool) air you receive. No more chilly or hot nights when you don’t want them! The Dyson Hot+Cool Fan Heater gives you a whole lot of bang for your buck and saves space in your room. It's two awesome products in one!
