Hello David Grand installation of a 15W heater on top of the keys and under the pin block is standard proceedure here. 15 Watts is very low - you can grasp it in your hand without needing a flame suit. (or oven glove) But it does keep down the moisture. I usually put them in that way in damp churches and village halls.
