The combination of a fan for cooling as well as heating seems logical. Dyson recently introduced its Hot + Cool Bladeless Heater to fill this obvious gap in heating and cooling products.
You may be familiar with Dyson products, which use a bladeless technology to deliver consistent airflow. Actually, a brushelss electric motor in the device’s base draws air in (up to 5.28 gallons of air per second), and then emits it through a slit in the tube.
Dyson claims its fans generate about 15 more times more air than that taken in through the base of the units. For the heater function on the Hot + Cool unit, this seems sufficient. A consistently warm current of air is generated. But for the cooling function, the air flow (while similar to that when in heat mode) seems a bit weak – probably because larger conventional blade fans can generate many more times air flow.
The cooling function of the Hot + Cool is great for smaller rooms, as with the heating function. For larger rooms, the cooling power may not be sufficient - if you’re used to higher air flow.
The main allure of Dyson products is of course the futuristic look, which does come with higher prices. The Hot + Cool Bladess Heater retails for around $380 - $400.
The Hot + Cool product comes with a remote control that magnetically attaches to the top of the device, a temperature guage for setting heating set points, the option of oscillation, and the ability to rock-tilt the device for more precise air flow. There is a two year limited warranty.
The bladeless technology has other advantages – no scorched surfaces to avoid, or protective heater grills that are problematic to clean.
