So, can you put a TV above an electric fireplace? In short, yes. For most electric fireplaces, it is perfectly safe to use a TV wall mount to hang a TV above your fireplace.
The only time this isn’t good for your TV is if the heat is blown directly upward. For most models, this isn’t a problem as the heat vents aren’t usually located on the top of the unit. If you have a cheaper unit with vents on top, this can affect your picture quality and cause damage to your flat-screen TV.
Now, let’s say you want to hang your wall mount LCD TV above your electrical fireplace. How high should you hang it? You don’t want to hang it too high.
You want the focal point to be pretty much at eye level. The height that you can hang your TV also depends on how far away the couch is from the wall.
If your couch is close, and you hang your TV too high, it will be like if you chose to watch TV sitting in the front row of a movie theater. This kind of viewing angle will cause neck strain. For comfortable viewing, mount the TV just a few inches over the mantle of your fireplace and make sure your couch is a comfortable distance away from the screen.
