I have always worked as a commercial installer for the GOVT. so my minimum for domestic water is copper.
Thanks Marc.
For the OP. I don't know your brand of heater but I have worked on many other brands and they are not that complicated.
If you can't get a warranty fix then get us the info. And we can help.

One advantage of Pex over copper is the fact it can be radiused, so fewer sweat connections to possibly leak.
Here's some pressure/temp info;
Pressure ratings, testing and pressure drop
