- Dyson Hot + Cool HF1 is a new fan heater with companion -App
- Equipped with a temperature sensor for energy efficient heating
- Can heat a room with 1C at as little as 100 seconds
Packing these sandals away. Empty your ice cream trays. Summer is over, winter is here. Or at least it will be soon. Relatively. Fortunately, Dyson has a new gadget to help take off the edge and keep chill out.
Dyson Hot + Cool HF1 is a fan heater that promises quiet, fast, energy-efficient heating, and it sounds like my perfect cold-weather case. In fact, it will also earn its stay in the summer because it can serve as a fan – but in these guard cool early autumn days it is the heating properties that I am most interested in.
This is Dyson’s first connected fan heater, which means you can check the setting via a companion app as well as on the machine itself. The important upgrade means you can turn on the heater through your app while on your way home and return to a toasty house.
I am also happy to see Dyson has included a thermostat. Running a heater can often be expensive, but here you can set a target temperature and HF1 will only do what it needs to maintain it, rather than wasting energy by making your room warmer and warmer until you finally notice that you have reached sub-tropical temperatures.
There is a timer that is useful if you want to use HF1 at the start of the night to stay cozy while you get rid of. On which note Dyson has thought -provokingly added a hibernation, where the screen dims and the fan heater works especially quietly.
HF1 can act as a fan or a heater, but it doesn’t look like the traditional versions of any of these things. The minimal, leafless design uses air multiplier technology to collect air from the surrounding area of the current blasting out of the ‘hanger’, which helps heat or cool the room faster.
It may seem to raise the temperature in a room with a degree (Celsius) in less than two minutes and you can heat a space up to 32C. There is a swing up to 70 degrees and the possibility of manually tilting if you want more direct heating.
The absence of grids and blades also means a safer device, but additional pain has been done to ensure that HF1 is suitable for homes with children and pets. There are no visible heating elements and all surfaces maintain low surface temperatures, plus it is automatically cut if tilted. Oh, and there is also a security lock on the control panel.
Dyson Hot+Cool HF1 will be sold in the UK in October at a list price of £ 399.99. I do not have pricing or launch datoinfo to the US or Australia, but based on British pricing it can be about $ 550 / AU $ 800.
