You can't just add a larger breaker and walk away unless the wiring in-wall is the proper gauge. You probably have 14g wire in your regular house wiring, which should only carry max ~1800 watts of electricity, and 1440 watts safely. It's mostly due to if you try and shove too many electrons down the wiring, it will overheat and cause potential fire issues. That's why you have a breaker in place, to prevent you from taking too much electricity down a certain gauge wire, by throwing in a 20A breaker, you're only endangering yourself.
A 'receptacle' constitues one plug-in, that you can plug one cord into. A typical wall box has two receptacles.
If you were worried about overloading the circuit, then just run a new dedicated 20A 12gauge line to the tank. If you plan on upgrading in the future run 2 x 20A breakers. You can split those into as many receptacles as you choose.
Cheers,
Scott
