Hi,

I have a old forced-air, hot-water heating unit in the cellar, hanging on
the ceiling.
It's a Trane "model S" Unit Heater, about 2'x2'x1' in size, electric fan in
the back of it.

The fan is really noisy, but motor seems in good shape otherwise.

What can I replace it with?

Are newer residential heaters of this type any quieter?

(This is a loud commercial unit, I guess, because the Trane website states
these "units provide uniform heating for large open areas in such
applications as warehouses, factories and showrooms.")


replace the fan motor, or the bearings in it. OR, rip it off and hang
a breeze box fan up there.
