As far as cheap gatorade and other bottles that drinks come in: those definitely have BPA in them and putting hot water in them is probably not the best idea.
I've never actually brought the water to the boil either for fear of it burning me while I sleep or damaging my bottle to to excess heat, plus it saves time and fuel.
We discussed the recent BPA scare in my plastics engineering class. The issue was raised by a guy working on his doctorate thesis. His testing methods were very flawed, but the media picked the story up first. Scientist have retested his findings and the levels were in the very safe zone. BPA mimics estrogene but must be consumed in far greater quantities than a person could ever get from plastic drinkware.
Not to freak you out, but most plastics contain BPA or other estrogen-like chemicals. Think about your tupperware, food packaging, water storage, cups, etc.
