It’s a gas fireplace that was used for the second time in 10 years, when our electricty/furnace went out for 22 hrs during last week’s Texas cold weather event. And it did a piss poor job of heating the house. It’s open hearth versus a closed box with a blower fan.It would be kinda difficult without a ladder. I guess it depends on preference, but always thought mounting over a fireplace would be a bad idea.... If there's a fire, you can say bye-bye to that TV... plus you'd be arching the neck UP just to watch.. (...unless perhaps the TV has some sort of tilt angle so you angle it DOWN for viewing..)
Still.. just my view.
