Space Heater. This is a great little fireplace space heater measuring 16 inches wide, 10 inches deep and 19.5 inches tall. We stand it on the silver liner that you may have if you wish. This works great! We added a piece of black coroplast behind it because there is no heat in the rear of this. The heat it throws out the front is amazing. From the front you cannot tell the back is not metal. This has a very realistic flame effect.
