What does the Water Heater Manufacturer recommend?
Exactly!
Not that you'd notice any difference between 3 and 3.5.
Lower is better from a few points of view,
Don't forget to use a pressure vessel as the PRV will probably prevent any backflow.
And you need a pressure relief valve connected to correct discharge pipework.
Some people will tell you a pipe can "absorb" some expansion. Popular view, but rubbish. They are all wrong, they've misunderstood the instructions.
