Then again there is nothing wrong with getting warmer water out of the tap, just make sure you condition it first (which you should be doing regardless whetheryou age your water or not).
Not to disagree with you, but it's worth noting that using warm tap water isn't always a great idea, especially if you live in an older house. When you run warm water through the pipes it can heat them and pick up debris or such that cold water might not.
I know that when I run hot tap water (this place was built in the 80's) I get all sorts of unnamed particles and debris in my water. I tried filling a five gallon bucket with warm tap water once, and it was so cloudy I couldn't see the bottom of the bucket even after letting it sit out! In comparison, my cold tap water was crystal clear. If you use heated tap water, it would probably be a good idea to filter it, just in case.
