Default Electrical Wiring Hot Water Heater

I'm also adding an AC 120V 20 amp outlet next to the water heater. After
looking around could not find a 20/25 amp dual breaker. The local ACE hardware
carried no 25 amp breakers. Home Depot had a 25 amp breaker but wasn't the
right type to fit my load center.

A 30 amp breaker might not trip or trip in time when connected to a 2000 watt
heating element. So I for now I'm going to use a 20 amp breaker (20/20, 20 amp
for the water heater and 20 amp of a 20 amp AC outlet)

If wanting a dual breaker I haven't been able to find a 20/25 amp dual breaker
anywhere. Perhaps a store such as Platt electric might have such a breaker?

I'm using 10 gauge wire. Purchased 20 feet 4 x 10 gauge. Hot, hot, neutral
and ground. $1.96 per foot to be installed into 1/2" PVC conduit as the main
part of the run is outdoors. Metal Clad can be used outdoor only if protected.
PVC can be used indoors, outdoors and underground.

Another option would be to swap out the 2000 watt heating element for on
that's under 2000 watt such as a ~1700 or ~1800, etc. watt element. Then one
can use a 20 amp breaker with 12 gauge wire and be up to code.
