I have two Cadet C202 electric heaters, one in our office and the other in living room. They are mounted in the wall. The depth of the heater wall can or guts for lack of better words are about 3 1/4". My studs are 2x4" (full 4" as the house was built in 1925).
The problem is they are mounted on outside walls so the insulation had to be removed to install them in the wall. My main concern is I can feel a light draft when I put my hand next to the heater grill (when they are turned off).
Does anyone have any creative advice for still putting some form of insulation behind them? Or, am I better off taking them out and either relocating or getting a better heater?
