How to choose

Read coverage as the maker's figure

Coverage is the maker's own rating for the room area a unit is meant to heat, not a measured result. The DREO is rated for up to 250 sq ft by the maker, the Amazon Basics for 150 square feet, and the Sweetcrispy for 107.6 to 161.5 sq ft. The SageNest gives 10-15㎡, and the De'Longhi is sized for small to medium spaces. Compare the rating against your room's floor area before choosing.
