I have three grand player pianos that all have a Dampp-Chaser installed.
I have to say that they work remarkably well (the Dampp-Chaser systems,
not the pianos).  Humidifying or de-humidifying an entire house here in
the desert of southern California could be quite expensive.

I believe these systems are the best insurance for any piano (no, I am
not a Dampp-Chaser salesman).  Short of having a humidity controlled
room, these systems offer the most "bang for your buck".

Sorry, I see a few lights blinking and have to sign off now and water
some pianos...!
