Marcel, 
 I service two buildings designed by Frank Lloyd Wright with radiant heat in
the floor. 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
