[pianotech] Dehumidifier rods

[limhseng at gmail.com]

Hi David,
My experience(in a high humid place) is that if the piano is placed in a big hall or area the rods under the piano doe not help a lot , the same goes for dehumidifier boxes that collects water. A 15 watt rod works wonders in the action cavity. But the worry is overheating of the pinblock over time, so in certain cases I have reduced it to a 10watt rod.

Does it actually do anything? I have a situation where a DC rod to impact
the action may be in order.  Unheated house, balance rail and action centers
keep swelling and seizing.  Don't like the idea of even a 15W DC rod right
under the pinblock, so does anyone have experience with a 25W 36" rod under
the key bed having a positive impact in a situation like this?  And why 36"
and not 48", or 50W rather than 25W?  Also, how far back from the front of
the piano do they recommend placing it?

DC recommends a 36", 25W rod under the keybed for the action, if needed.
