UPC does not permited PVC to be used for potable hot water. So don't put it inside the house. IF you have o use plastic pipe use PEX of CPVC both of which are OK for hot potable water. In answering you question PVC can handle 120 degree water temps
Hot? Cold? return? fire suppression ? Non Potable?
yes you use cpvc pipe
on a potable water system you can either use a water hammer arrestor or an air chamber. An air chamber is a length of pipe with a cap on it (6"-8") facing up
Pex, a flexible potable waterpipe is the preferred. You can use PVC that is potable and copper that has been sleeved. No joints of any kind should be used on underground portions of the piping. That is why pex is preferred as it comes in various sizes and lengths in rolls.

Any potable supply In reality, although the water heater can use a supply from any potable source, it is always better to have its' inlet connected to a water tank. There are a number of advantages- 1. There will be less water pressure on the inlet pipe of the water-heater. This is important for the warranty, as 99% of warranties insist that this is so. 2. The water in a storage tank will be invariably warmer than that in the pipes, therefore the source inout for the heater is warmer, making the unit more efficient. 3. Finally, should there be a water disruption, you will always at least have a supply of water from the tank, at least for showers.
