We recently installed window seats made of MDF and are about to reinstall our electric heaters – since they sit on the front and are not enclosed in any way, is it OK to have them on an MDF "wall" as opposed to the standard drywall?
The window seat is between 2 bookshelves, so there’s nowhere else to put it – the heater was originally directly below the window…
It is in a bedroom in a Cape Cod style house, so the bookshelves are under the slanted part of the ceiling, and the window seat is in the "cut out" between them
