Heat for the piano

[Farrell]

John, I think he has a great idea with his piano-environment setup. He is
trying to stabilize BOTH temperature and relative humidity. Great. Just
gotta be aware that with temperature stabilization within the piano will
increase RH fluctuations and make it more important that the DC system be
properly sized and working properly. I'd love to see a spread sheet of data
for days, temp. in and out of piano, and RH in and out of piano. I guess it
was just too much chemistry and physics in high school and college :-)

you growing in the bottom of those church pianos anyway?  Or are you just
trying to shine "light" on a job well done?
