Mounting a TV Above a Fireplace: Heat, Height, Mounts

On this page

The fireplace wall is where the couch already points, so it is where most people want the TV. It is also one of the installs with the most to think about, and for good reason: heat and height are two ways a fireplace TV goes wrong.

Neither one is a dealbreaker. Here is what to check before mounting a TV above a fireplace, and when another wall is the better choice.

Can you mount a TV above a fireplace?

Yes, if the wall stays cool enough and the screen is not too high. TVs are usually rated to about 100 to 104 F, so check the wall temperature with the fire running, follow the fireplace clearances, and use a tilting or pull-down mount when the TV sits well above eye level.

Heat: the part that can void a warranty

TV makers rate their sets for the air around them, and most top out around 100 to 104 F. A gas fireplace puts out 20,000 to 35,000 BTU an hour, and much of that rises straight up the wall. Heat damage from a bad spot is not covered by most TV warranties.

A quick test: run the fireplace for an hour, then put your palm on the wall where the TV would go. If you cannot keep it there comfortably, the TV should not live there either, at least not without a heat solution.

The wall 12 inches above a wood-burning fire can reach 120 to 150 F. That is well past the 100 to 104 F most TVs are rated for, which is why open wood fireplaces need the most care.

A mantel helps, a little

A deep mantel pushes some rising heat forward off the wall, and it gives the TV a visual shelf to sit above. But fireplace makers are clear that a mantel only deflects heat slightly. It is a help on a warm wall, not a fix for a hot one.

The fireplace manual lists clearances for anything heat-sensitive above the opening. Read it before drilling, and follow the larger of that number or what the TV maker allows.

Height: the part your neck notices

On a normal sofa your eyes sit about 42 to 48 inches off the floor. Above a fireplace the screen center can end up at 60 inches or more, and looking up more than about 15 degrees gets uncomfortable over a two-hour movie.

Two fixes work. A tilting mount angles the screen down toward the seats and cuts glare. A pull-down mantel mount goes further: the TV sits up high when you are not watching and comes down to eye level when you are.

Fireplace type	Heat on the wall	What usually works
Electric	Low, heat often vents forward	Mount above, fixed or tilting
Sealed direct-vent gas	Moderate	Check the manual, add a mantel or tilt
Open wood-burning	High	Test first; often a pull-down or another wall

What to check on a fireplace install

1. Wall temperature

Run the fireplace for a while beforehand and check the wall, so the TV goes on a wall it can actually live on.

2. What is behind the wall

Brick, stone, a wood-framed chase or a metal flue each need different anchors, and a flue is never something to drill into.

3. Screen height

Measure from where you sit, not from the mantel, and pick fixed, tilting or pull-down from that.

4. Power and cables

Plan how power and HDMI reach the TV before mounting, so nothing hangs down across the brick.

Common questions

Will heat from the fireplace damage my TV?

It can if the wall gets hotter than the TV's rated range, usually around 100 to 104 F. If the wall is comfortable to touch after an hour with the fire on, you are generally fine.

How high should a TV be above a fireplace?

As low as the fireplace clearances allow. Keep the bottom of the TV a few inches above the mantel and use a tilting or pull-down mount if the screen center ends up well above seated eye level.

Can you mount a TV on brick or stone?

Yes. Brick and stone hold a TV very well with the right masonry anchors. The anchors should go into solid brick or stone, not the mortar joints, and never near the flue.
