Hello Brett, I personnally would insist on the humidistat installed with at least 75 watts. The key for me would be installing and undercover as well as a string cover. If there is too much air circulation under or over the soundboard and the pianos are as exposed to the elements as you say they are, reducint the volume of air to control is the solution.
