The immersion will draw much more than 13A when the element is cold.

No they don't.
Nichrome resistance doesn't change anything like that of tungsten,
and in any case, the temperature change is only a small fraction
of that of a tungsten filament.

1.414x 13A = 18.38A, well above the 13A rms current. If mains voltage goes to the upper end of its permitted range, the current will be higher again. So the OP needs a 20A relay at least.
