Question: Can I hang it on the wall?
Document: I bought this heater exclusively to hang on my bathroom wall as, due to various reasons, I was unable to have one installed in the ceiling or wall. I have now been using this heater for about 1 year and a half and a completely satisfied with its performance. Keeping the bathroom door shut with the heater on raises the room temperature approximately 5+ degrees within just a few minutes.
As I said,once you get the hang of it,it's simple!And again,once you get the setting you want,the button DOES become a one-push button! To wrap this up,this is a nice little heater and it does what it's designed to do.It puts out more heat than you think it does,is light-weight and {once you get the hang of it}is simple to operate.
My main bedroom is fairly large and it works great with the door close. It does not heat my entire living room as it is a double polar but it takes the chill out. The bathroom is warm in about three minutes. They are nice because you can hang them. When I wanted to heat up the living room a little more, I just took one from the second bedroom.
For the price, this one is cheaper, and I like that it is flat on the bottom, but can also be put on the wall...something I have yet to attempt, but with a cat, might do it this winter.
I love that I can mount this on the wall and it doesn't get knocked over by the dog's "sweeping joy". Also love having one in each room, so I can leave it at a lower temperature if the room is unoccupied, and turn it up when I want to - like in the bedroom at night, 65 or 70 with the door closed and a heavy quilty comforter is perfect!
Bought this little Holmes HFH442-UM in November 2013 as our wall heater in our (approx) 500 square feet living room/kitchen area has problem (not working at all).I have been using it almost every night for Seattle weather. I put it on low setting & this little heater warms up the room.
I recently build a terrarium that houses live plants and day geckos into a basement wall. The back of the cage sticks into a closet that can get fairly cold. I use the thermostat on this heater to make sure the ambient temp in the closet never dips below 75. So far it's worked as advertising and mounting it to the wall was moronically easy.
I own two of these, one in a small bathroom, and one in a larger 9' X 9' bathroom.The unit is compact; it has a plastic part that you fasten into the wall, and then the heater rotates sideways to fit into it, then back to vertical to lock in place.The controls have a power button, a LOW button, a HIGH button, and several temperature settings. We don't use the temperature settings, so I won't comment on them here.
I got two of these heaters last winter when our furnace died on us. They were cheap and worked great, so great my mom stole one from us and took it home with her and put it in her bathroom. The things I think I like the most about this model is that it is wall mount-able. Good for in our daughter's bedroom. I've got it up just out of her reach but low enough it heats the entire 12 by 12 room evenly. And the plug that is on it.
I bought this heater last year for the guest bathroom thinking it was inexpensive, and small.Now that it started getting cold again I could not find the bigger heater for my master bath, so I got this "little one". I mounted it on the wall (away from the bathtub and shower). It took all of one minute to mount it.The thermostat setting is great because I leave the unit running all the time at 65 degrees, then bring it up to 70 in the morning.
Answer: Not easily.  There is no hook or fixture built into the unit, nor did any corresponding hardware come in the package for it to be attached to a wall.  If you can install a small shelf (at least 10 inches wide, 7 inches deep) to place the heater on - that would work.  On back of unit you will find various vents and plastic angles on which you might be able to attach some kind of hanging hardware.  But, like I said, not easily.  Hope this helps.
