Short of moving the TV higher or off the wall, can i rig a 'shroud' of some sort to put over the top of the fp to deflect the heat away from the bottom of the FP? Any suggestions would be great.
Hey TripleM (I think I've seen you on the sammy threads?), I mentioned in my post above yours that I went through some of this planning. While my current Plasma I just bought is mounted over a pool table, the next one will be going over the fireplace, where I have prewires from new construction.
One thing I wanted to do was lower my mantle, and make it deeper, mainly for aesthetics, coz the current mantle isn't much deeper than a low profile mounted panel, so I want the mantle to be deeper for the proper look of dimension.
As it is now, I've left a fire run for awhile, and raised the temp at the thermostat in same room as fireplace, to an uncomrotable (for me) 78 degrees, and w/ a thermometer on the mantle it only got a few degrees above that for me. I have a 'zero clearance' vented gas appliance w/ a glass front on the insert. I figured if I went forward w/ my plans to extend the mantle from about 6-7" deep, to 9-10" deep, and possibly lowered it a little, that might deflect even more heat away from where the tv is.
Again, it should be looked at from the perspective of the 'difference' in temperature between the panel area above the fp, and the rest of the room, when the fp is on, as well as the temp at the panel in and of itself. In other words, if you let a fire burn long enough and hot enough, and have a reasonably well insulated house, and you get the temp in the room to 88 degrees, and the panel area runs 5-10 degrees warmer than that, it might be an issue. But it it only runs 5-10 degrees warmer than the thermostat, and you keep it at 70 ish, then you're only 80 ish or less at the panel. Hope that makes sense, in a general sort of way.
As I mentioned in my previous post, depending on how your trim work is, and whether or not you have a mantle already, it may be an easy fix.
If you don't have any mantle, you can see in Bullet's picture an example of adding one. You can even buy things like this prefab from home improvement stores, and bolt it to the wall.
Or, if you have a trimmed out FP and mantle already, you can do what I planned to do, and just add another layer to it, since trim work is just layered wood stained, or caulked and painted anyway, so it will just look like another more elaborate layer of the mantle, but you can add as much depth as you want, within reasonable ratio to the overall look.
If it helps, here's my no plasma yet fp, to see how my mantle is, and is probably currently ok to hang a tv already, but if I deepen the mantle, then I'll have even more heat protection:
