matching the temp and ph perfectly is ideal of course, but when I do a water change on my 220 I use cold water. I just try not to change enough to drop the temps in the tank more than 3 degrees. some will say not to do this but its always worked for me with no problems that I can see.
As far as hot vs cold, I do not know, I would say as long as you do not change the temps in the tank much and you don't let the water spray directly onto any animals is probably okay.
