"They" don't have a clue if they suggest a 20A c'bkr.

You need 30A.

That depends on whether the 18A is peak, or continuous, current. If the
continuous current is 16A or less, a 20A breaker is fine. If it's over 16A,
then a 30A breaker is needed.

Thermal/Magnetic c'bkrs are designed to operate at 80% of rating on a
continuous basis under normal ambient temperatures.

Exactly -- which is why it's important to know whether the 18A is peak or
continuous.
