I almost never recommend the piano life-saver system in a home. It is always better to regulate the humidity in the room. The moisture king system works to do this quite well. I even have some customers who have gone to the expense of installing a humidity system into their heat pump. this is far better for every aspect of the home as well as the piano. Either way, if you install the life-saver system, be sure to do a good job for the sake of the piano. God Bless, Mark ------------------------------------------------------------------------------ Mark, I agree about the need for correct D.C. installation. Without detail I have seen some configurations that at best are ineffective. I almost never recommend the piano life-saver system in a home. It is always better to regulate the humidity in the room. This is where I respectfully disagree.Here in New England we have humidity swings from 20% to 80% in homes without a whole house climate control system. Combined with open floor plans room humidifiers generally fight a losing battle . A large percentage of homes here have baseboard heat and no central air and are without ductwork making the installation of a humidity system too costly for most. April can be rainy and cool and I find very high humidity in homes and the people with sweaters on. They are certainly not turning on the A.C. and with a sometimes swampy early spring a piano can go 20 cents sharp in a few weeks . Throw in a cold December and the R.H.- pitch will drop in the opposite direction just as fast With a few notable exceptions my "home" clients keep their systems well maintained --I.E. fill fhe thing and add the capful of D.C. juice when the light goes on. I take care of the pads etc.It is the institutional installations that are alway's dry or unplugged in my experience. One prestigious private school here has tried the music teacher ,the custodian and even a student to be in charge of the filling without success. So my experience is the opposite .I almost never recommend a system for institutions and have a long list of stabilized pianos in home installations. Just my take--Your mileage may vary.
