First up: this convection heater from Mill Heat. It’s designed with a wire-heating element with three different settings so that it delivers not just high efficiency, but extremely rapid heat. (Come on, is there anything more shiver inducing than waiting for a space heater to crank it up?) Even better, the Mill Heater is actually designed with the aesthetic of your home in mind. Rounded edges and aluminum feet to make it look like it’s almost hovering above your floor. Plus, the black and white color palette helps you maintain a modern feel while the slim packaging means you can tuck it away in a corner—out of sight out of mind. There’s even an interior fan to help the heat circulate better and, when it’s on, it’s super-quiet—a major perk for anyone sensitive to the white noise of a space heater at night.
