The current heat source in the house a Cadet in wall unit heater in each room. They are really noisy and often emit this "iron left in one place too long" odor from (I presume) scorching dust.
I've seen some wall mounted heaters that look they might be more or less "drop in" replacements – for example the Stiebel Eltron CNS series.
Is this likely to work or am I chasing a unicorn? Ultimately I'd like to go to a mini-split heat pump system, but that isn't in the budget right now.

When was the last time you cleaned the heaters? Cadet recommends once every 6 months, which I feel is overkill in most cases, but I bet this is something you've never actually done. This should fix the smell at least.
