Another from I found off the net https://learnmetrics.com/what-size-tankless-water-heater-do-i-need/

If you need further help, send me the info and I will tell you the flow rate needed.

Here's the Rheem charts. https://www.rheem.com/tankless-electric-water-heater-sizing-tool/

Looks like Baz is good for about 3 gpm in Florida.
