Hi it's Jessica with Dyson Customer Service.
The AM05 is intended to heat both large and small spaces, and it will continue to heat and circulate air until the selected temperature is reached.There is no specific range or square foot area its coverage is limited to, however, the time it takes to heat a given space will vary due to a number of factors such as the size of the room, the thickness of the walls, the number of windows, the temperature outside etc.
Please let us know if you have any additional questions and we will get back to you as soon as possible.
