We bought a Muskoka 36 inch wall mount heater 2-3 years ago. There's also a 42 inch model.
(VT you may recall my cold front bedroom problem. This solved it)
It is perfect. Mounts directly on the wall. (easy do it yourself) Uses standard electrical outlet. The air blows out the bottom and away from the wall. The wall above and below stay remarkably cool. The heater is beautiful when off, more beautiful when on. Takes up no floor space. Can have it operate with or without heat. Uses almost no electricity when using just the fireplace function without heat.
We use it as a supplement to a single chilly room on these cold mornings.
I see that Amazon has it for $150
Home Depot, Lowes and Walmart also have it.
