I purchased a heater just like this one over 10 years ago to go under the desk of our shop foreman. When he retired 10 years ago I got the heater to replace the one under my desk. I just replaced the heater about a month ago because the back fell off. We have stained concrete floors and our office is a large open room, and it gets chilly. This heater puts off just enough warmth to keep me toasty. I was excited to find I could get one just like the one I had.
