Pianos are made primarily out of wood and metal parts. Both materials are significantly affected by temperature and humidity. Combined with the fact that pianos are extremely complex instruments with thousands of small parts under immense amounts of tension, the smallest changes in relative humidity can have a significant impact on the tuning and stability of the piano.
Wood expands as it takes on moisture, and contracts as it loses moisture. This is the most basic and important reason that humidity control is so important for pianos. In southern New Jersey, I have found that indoor relative humidity is often extremely low during the winter months, with heat running regularly, and dry air circulating around the piano. Unfortunately, relative humidity often gets very high during the summer months, particularly in churches and schools, or homes with no air-conditioning. I have seen these conditions take a severe toll on a number of otherwise fine pianos.
The Piano Life Saver system by Dampp-Chaser is a self-contained humidity control system that is installed inside (verticals) or underneath (grands) your piano, and can cycle between humidifying and dehumidifying modes. It keeps the crucial components of your piano, such as the pinblock and soundboard, at nearly constant moisture levels year-round. The cycling between humidifier and dehumidifier is controlled by a sophisticated humidistat, and the system uses very minimal electricity due to its small size and focused application.
I can whole-heartedly recommend this system, and due to the positive results I have seen and the dire need of such a system in our climate, I have acquired an installer certification with Dampp-Chaser. I particularly recommend the Piano Life Safer system for churches and schools, as they typically have extreme temperature and humidity swings during the course of each week. It is also of great benefit in homes with forced air heat, or with no central air-conditioning systems.
