Home was built in 1962, but these look to have been installed sometime after the home was built. We have baseboard heaters (run off a boiler) and the upstairs of the house has 5 of these units as well. I know they also run off the boiler, and they also have built in blowers. The blowers are noisy on a few (to the point they wake us up when it kicks on at night) and I'd like to take a stab at repairing them, but I have had zero luck figuring out the make/model of these units, so I have no idea what schematics to be looking for. Anyone come across these before? Right now I just have the noisy units turned off rather than listening to them. I pulled the cover off last night, but I it looks like I can't even see the blower fan without removing more of the internals (mostly radiator piping - can take a picture of that tonight as well).
