Humidity Control

[John Ross]

Hi List,
We have storage box/ compartment, for a Steinway D, at the back
of an unheated, except for circulated air, stage.
What would be the best method of controlling the environment for
this piano, which is frequently moved to the stage for recitals
and such.
1) A full Dampp-Chaser system installed on the piano?
I feel it would show to the audience.
2) Can a Dampp-Chaser system be installed to work properly in the
box?
3) Just have a humidifier, room type, and a heater installed on
the wall of the box.
4) Should the box be insulated. It is open at the bottom, as the
walls are on hinges and casters, and it just folds back, once the
top is raised. It takes up very little room when the piano is
out.
I was wondering how your Universities handle this problem.
Thank you.
