I hesitated on purchasing this fireplace because it had to cover the existing fireplace in a 100-year old home that had an old gas heater in it which was removed.  The chimney had been blocked in years ago so I didn’t have many options.  So far, I’m extremely pleased with the fireplace and the options on heating although i haven’t put it to the test of heating the room for more than an hour Assembly wasn’t a breeze, but it has enhanced the look of my master bedroom.
