I can confirm that. Here in Germany this kind of heating is quiet common. 
Often it´s a killer for old pianos. Newer/modern pianos survive that heat 
assault without any damage, but all screws have to be tightened and it 
should be tunend twice a year: 4 weeks after the beginning and 4 weeks after 
the end of the heating period. It helps a little bit to locate the piano 
where is no heating coil and to istall a reflecting foil under the bottom. 
And using a humidifier. But all these steps are only a compromise. If a 
customer with that kind of heating asks for consultance about buying a piano 
I strictly recommend a newer/modern piano. I never ever saw a newer piano 
with loose pins or cracked soundboard. I am astonished about how often I 
read in this list about loose pins at newer pianos.
