Run this in my 16x10 shed in Ireland. Keeps it at around 22-27c. On the lowest setting.. The remote for it has a range of 40 feet from the house. Highly recommended it. Was looking to get a second model. To have as stand by and use for the house. I run it over night for about 6 to 8 hours. Keeps the humidity down as well. I have a number of aquariums in the shed and the humidity can be up at 65% to 70% some times. But after running the heater for a couple of hours. It drops to 45% . Nice dry warm heat. Have recommended to many friends. In the picture you can see the heater mounted on the bottom of the rack. Makes it super comfortable to do work in the shed.
