 My question is this:  Can I expect a heat bar under the keybed to
 alleviate the tightness from humidity?  Should it go inside the action
 cavity?  Or is there no way to know until I know if the sluggishness is
 from key bushings or action centers?  And what wattage should I use?
 Or, do you think I should forget about humidity control and just get in
 there and fix the problem >>
 Clyde:

I have noticed the problem on Steinways is much of the time a problem with 
action centers getting overrun with vertigris- a green chemical reaction 
which attacks these center pins.  The problem is amplified due to high 
humidity, I am sure, and is more noticeable in the treble because she 
probably doesn't play there as much as the rest of the keyboard.
Use Protek on the center pins and "flex" them individually until you notice 
improved movement.  Some Techs feel this is attacking the problem and the 
problem will return.  I agree, but find this is a 4-5 year solution.
As far as DC system: if humidity is always a problem, and she seldom uses air 
conditioning, I would install just the de-humidifiers but include a 
humidistat.  Donot, under any circumstances make this installation without 
this control.
