Cozy Cove Heater on a wall outlet?

Wall mounting it should work fine since the cord comes out of the unit, not the bracket. Mine hangs above a dresser and the plug goes straight into the outlet below with no issue. As long as the outlet isn’t directly behind the mounting plate you’re good 😄

The wall mount itself is not the part I would fuss over, it is where the cord lands once the thing is up there. Mine sits on a bracket in a spare room and the plug goes in fine, but the cord still hangs down in a visible loop and I had to nudge the bracket a little off center so it did not fight with the outlet plate. That part was mildly annoying and took me two tries to get right. The bigger thing for me was noise. I run it in the evening while reading and the fan is not silent, it is more of a low steady hum that I notice when the room is otherwise quiet. Not a dealbreaker, but I would not put it right next to where someone sleeps. Heat wise it takes the chill off a small room fine, though it is not going to rescue a big open space. If the outlet behind the couch is the only spot, I would check whether the cord actually reaches once mounted before drilling anything. How far is the outlet from where you would want the unit up on the wall?

That reach sounds fine, the awkward part is going to be getting your hand back there to push the plug in. I dealt with something similar with a lamp cord behind a recliner and it was a two person job for about thirty seconds. One thing I would do before mounting anything is plug it in and let it run back there for an evening. Mine runs warm on the casing after a while, not hot enough to be scary, but I would not want it jammed right up against the back of a couch cushion with no air around it. If there is a bit of clearance once it is up on the wall you are probably okay. Also worth checking whether the couch can slide forward a few inches, that made the whole thing less cramped for me and I did not have to move it far.

Mine didn’t sit flush once it was up. The bracket holds the heater but the plug sticking out of the back meant I had to pull the whole thing off the wall a bit to get it in. If your outlet is right in the mount’s path, that is your problem, not the cord reach.

Mine sits above a dresser outlet and plugs in fine.

Mine ended up too close to the couch, so I just put it on the floor.

If it were me, I’d skip the wall mount and just set it on a small side table or stool behind the couch instead. You get the height without drilling anything, and the outlet stays clear. I’ve done that with a similar little heater and it worked fine, though you do have to make sure the table is stable enough that a bumped couch doesn’t knock it over. Wall mounting sounds neat in theory but I’d rather not deal with the bracket and cord alignment just to save a bit of floor space.

I’d probably just mount it above the outlet and let the cord hang down to plug in. As long as the bracket sits high enough that the plug isn’t jammed, that seems fine. The heater is small enough that it shouldn’t be in the way up there.

Wall mounting is fine but I’d check the bracket height before you commit. Mine sits a couple inches above the outlet and the plug fits without the cord bending weird, so no extension cord needed.
