Heat for the piano

[Farrell]

I think you may be asking for trouble having a DC system (dehumidification I
presume) regulated by a thermostat. That will indeed heat the inside of the
piano, but it will do this in the winter (I assume you are in a cold
climate) when relative humidity (RH) is low and it will lower the RH inside
the piano even more, possibly causing damage.

My information is that it is more important to regulate humidity than
temperature (although the post below makes a good point about tuning
stability). Install a good DC system with appropriate capacity and consider
it done. Good luck!
