This heater can put out some heat!! I set mine at 60 degrees and it stays 70-80 degrees in my well insulated small home. It is NOT a wall insert - it mounts in the floor- I purchased it to mount on the wall and then had to call Wayfair because it does not mount on the wall as advertised. You can see the holes I have had to fix in my wall because this heater does not mount on the wall.. Lisa. Carthage, NY. Mon Dec 18 2023
