Love it

Purchased for a large bedroom and on the lowest setting this thing throws out a lot of heat. Much better than expected and I'm about to order another to put in the living room. Was also very easy to mount on the wall and hook up.

The heater is amazing but I'm waiting on the propane guys to come on the 12th of February to install. I will tell you more after that
