Here in the = Tampa Bay area of Florida I have never installed the humidifier portion of a = DC system. My Boston grand has 190 watts of heater rods and an H2 = humidistat. Pitch simply does not vary on the piano and you won't find any one string more = than two cents off after a year. I think one winter day I noticed = an RH level in my living room (where the piano is) down at 35% - but that = is the lowest I have observed. Simply does not make any sense to me to install = the humidifier and all its associated headaches.
