Here are the plans.

If you are replacing and existing hot water unit, you might consider
reusing all the elements & thermostats, instead of buying all new. This
will save you a few bucks.

To complete the unit for home use, just install a well pressure switch
with pump protection option on the inlet side. You will have to add a T
fitting with a adapter for the smaller pressure switch NPT threads.

Keep in mind that you may have to adjust the low pressure safety
settings, depending on your water pressure. You will also need to reset
the unit manually if you shut your water off, and if the pipe loses all
pressure for any reason.

Big part of it was telling how to make a good solder joint.
Nicely done on that.
But after discovering Copper-Bond, I no longer solder my
copper pipes.
If I were doing it, I'd use a strap under the pipe clamps to
serve for ground continuity.
