Undercovers

[Frank Cahill]

Bob, I see a lot of installations with a heater bar and a humidistat,
but no humidifier. Have you ever tested such a set-up? My feeling is
that without the humidifier, it would not work very well.

Some very experienced techs in this area don't install the humidifier
because they feel that many people would not "water their paino".

I install complete systems.
