humidifier connected to hot water pipe

In the home that I am currently working on, I noticed that the homeowner’s Honeywell Power Flow-through Bypass Humidifier (HE360A) is connected to the hot water supply pipe.
Every humidifier I have ever installed, I’ve connected to a cold water supply pipe.
Your thoughts?

WOW!!! What a Ride!
Forget the primal scream, just ROAR!!!
I dunno. Honeywell says you can use hot or cold, soft or hard.
Hot water is a good choice, provided the unit is designed for it. More water into the air.
If the humidifier is rated for hot water then this may be a good idea (depending on the situation). It allows the humidifier to work effectively when just the fan is running on the furnace (no heat).
It's the way ours is rigged. The humidistat turns on the furnace fan. Works much better in the "shoulder seasons" where the furnace isn't running much.
Some humidifiers are designed for hot water. My Aprilaire works that way.
And I believe the Honeywells are rebadged Aprilaires.

When the HVAC guy initially installed the Aprilair humidifier in my house 35 years ago he connected it to the cold water line. It did not work so he reconnected it to the hot water line and it worked fine. Just had a new unit installed and it was connected to the hot water line from the start. The only thing that concerned me was the loss of heat radiating from the small copper line. I insulated the line so the humidifier got the advantage of the dollars I was spending to heat the water.
Right. When I installed our unit I snaked the copper line through a length of vinyl plastic tubing to insulate it.

Insignificant. Not an error. Not better than cold.
I use hot simply because the water is closer to evaporation anyways, and I'm paying for hot air that will be used to evaporate that water in my humidifier. Of course, I'm also paying to heat the water in the first place, and the difference is negligible.
