These systems are pumping liquid through pipes installed in concrete floors. The Unitarian church has a special quilted cover with an extension that wraps underneath the piano. The Yamaha C7 is on a tripod as it gets moved often. The piano is very stable, however they do not have air conditioning and in the Summer the humidity raises the pitch. In this setting I service the piano about once a month. The two German S & S Ds are in a private residence and are also very stable. Humidity control is with a humidifier/dehumidifier system in the room. A carpenter made a plywood footprint that sits underneath the piano to deflect the heat. Additionally the plywood enhances the sound in this studio as the floor, walls, reflect a live sound. I have observed that the temperature of the radiant system can be kept lower and it is steady compared to a forced air system. Keep in Tune. Joel -- Joel A.
