This heater has kept my house toasty warm during the snow storm that has hit Central Oregon. It's a wonderful unit that was ready to use straight from the box. I am using it free standing in my living and all I really needed to do was add the legs and wheels. Its flat design is nice because it takes up very little room and the wheels make it mobile so you can easily move it around. I have not tried mounting it and probably will not because I like being to move it around but it looks fairly easy to mount if you wanted to
