If I get a new oil furnace with humidifier and with AC, is there a
method provided to turn the humidifier off, especially the water,
OTHER THAN the little valve on the water pipe that feeds the copper
tube to the humidifer?

Is it *automatic* that the humidifier doesn't run when the AC is on?

Or will I have to turn off the water supply? My little tapping
valve worked fine for a few years and then it got difficult. And it
was accessible for a few years, and then things got piled where I need
to put a chair to reach the ceiling. So it would be nice if it turned
off some other way.

When the humidifier doesn't run in the summer, is it only that the
electric motor doesn't turn the wheel? Or is the water turned off
too?

I had no room for a motorized humidifier in my current furnace and the
only one that fit used T-shapped fiber plates to suck water out of the
pan, which filled up the ends of the T so that the hot air going past
was humidified. A valve turned the water off when the water level in
the pan was high enough, but eventually that didnt' work well and the
water overflowed the pan through some little hole, and dripped on the
flue collector of the furnace, causing that to rust out. Maybe some
water even dripped down the main heating duct back into the furnace.


Is there any trick to replacing the tapping valve in the same place
that the current valve is? Or would there be an advantage to tapping
a hot-water pipe instead?

Thanks a lot.
