I recently installed a 7-part 2 tank system into a Bosendorfer 7ft. The client called and is concerned that the system is drying out his piano. He thinks that heater bars are too hot (he says they are too hot to touch for even a few seconds). He mounted a hygrometer under the soundboard for a few hours and says it is reading 35%. Has anyone ever had problems with a system malfunctioning and demolishing a piano? The client has since unplugged the system until I can get out there to look at it, but I don't really know what to look for. Does anyone have any ideas or comments?
