I need a pic. It depends on the heat source if electric a diifernt thing than hot water . Post a pic here with the info about heat source then we can answer . Post here in comments DO NOT start another post.

From the LG Owners Manual (example):

"Do not place the TV and/or remote control in the following environments:

- Near any heat source such as stoves and other devices that produce heat."

From Samsung:

"Mounting your TV above a fireplace

"We do not recommend mounting your TV over a fireplace. Your primary concern will be the heat; Samsung TVs should never exceed 104°F. Before you even think of mounting a TV above your fireplace, light a fire and check the temperature first."

Here's a couple of ideas for you. The storage unit can be wall mounted leaving the bottom open for the baseboard heaters to be left undisturbed. If you have the room leave the fireplace separate from the tv, but if not mount the tv above the fireplace since it's electric. In general these tend to look more modern in style, so not sure what you're going for. Hope this helps.

Thank you see picture attached, just to clarify it is an electric fireplace with vents in front, the tv will be around 4-5 feet aboive it and not in direct contact with the heat so I am worries about that. The heat from the baseboard is from hot water not electric.

oof, hot water is a big deal. unless you're prepared to change your furnace to forced air throughout the house, it's not easy to make these disappear, and moving them means digging into the floors.

any chance you want to show us the layout/floorplan of the room? maybe there's a better spot! (or maybe you can get a fireplace that generates heat!)
