Using this heater in my 12 x 20 electronics workshop. I was running an oil filled radiator for the main heat and an older, cheaper baseboard style as secondary heat when the temps drop below 20 degrees. This heater has worked better than I anticipated. Of course my shop is well insulated, but it has replaced the radiator as the main heater. So far so good. It runs quieter than expected also. There was some plastic odor when I initially turned on, but it wasn't bad, and after a couple days, I don't notice it anymore. Fit and finish are excellent, and it arrived with no damage.
