Go low wattage. 8 to 15 watts. I've seen a lot of them mounted on the stack here in Panama. In the long run, a heater mounted under the pin block will loosen the pins, but without it, the piano is unplayable because of seizing action centers. Which is worse? No one wants to pay for repinning, OR new pins, so it's a catch 22. I've seen a lot of 25 watt rods installed, but that's too high. 15 is even a little too hot, but it will do a good job.

This particular piano has recurring problems with seizing jacks and sluggish hammer flanges due to high humidity. I don't generally prefer putting a heater bar under the pinblock, but I'm tempted in this situation to mount it on or near the action brackets so that it might radiate a bit of heat toward the jacks and hammer flanges. Any experiences out there. How low can I go and still get some benefit without down side potential: 15W, 25W??? The piano will be fitted with a regular DC system (dehumidification only). Appreciate any comments. David Love davidlovepianos@earthlink.net _______________________________________________ pianotech list info: https://www.moypiano.com/resources/#archives
