I think that the backs of them are too close to the wall.

Do they/it have a condensor on the back? More recent models don't and
the sides get warm...

Models that we've had with a condensor on the back had plastic
spacers attached. However these could rotate to the same plane as the
condensor. Which ever type I'd go for a couple of inches.
