The usual remarks about the safety of scalding water anywhere in your system go here. Physics says the life of your tank will decrease, but not enough for you to notice. Everything else being equal, hot water has a slightly higher pressure, but expansion tanks are there to deal with that very problem. The one place you might notice a difference is in ...

Your best bet would be an IR or instant read thermometer. You should test it from the closest faucet to the hot water tank, and make sure to let it run for several minutes first.

What is the temperature where the hot water heater is? The tank is big and insulated and while it will take longer to freeze, if the ambient temperature is below freezing, it will eventually freeze. When pipes freeze, there is much less water volume so they will freeze much faster. Also, copper is an excellent conductor, so standing water in copper pipes ...
