Not if you use comtainers that are small enough to allow the air to pass over and around it. The heat warms the water, and it evaporates pretty quickly when the heat's on a lot.
My house is old (built in 1947) and the registers are fairly large, so finding containers that won't block the heat's easy for me.

I remove the register's top cover, and set the pan right down into the heating duct.
They're easily refilled with a watering can, after taking the cover off, of course! ;)
Here's a picture of one. (Sorry about the mess around on the floor- as I was getting the camera, one of my cats decided it was a good time to knock a couple of pots on the floor. Just one more mess to vacuum...)
