I have a old forced-air, hot-water heating unit in the cellar, hanging on
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.")
