Mokapots, Moka, or Stovetop Espresso, Period.

Okay what am I doing wrong? My coffee has been coming out warm and not hot. Should I do a lower heat setting? That might sound odd but my coffee has been brewing quickly so I am thinking maybe I have it on too high of heat and it is making it brew before it is boiling? Any thoughts? To me it tastes great but I could be doing it totally wrong lol
