"What (if anything) does one need to install such a beast? Would it be mandatory to use a licensed plumber?"
You will likely need to have a new gas line run to the WH - it takes a bigger one to supply the
increased BTUs needed for an instant use / tankless unit (bigger than a stand by system)
It also needs to have a new vent system installed which likely means cutting through the sidewall of the house.
It's probably a bit more advanced than typical handyman work - but that depends on the handyman,
I just wouldn't want to be his first one.
