Try: putting it on the highest setting,
Use less water (10+liter is a lot and can happen quickly in big pots),
Plug it into 3 phase power
Make sure to use the highest power section
In a lot of cases ceran cooktops have higher power delivery to the pot than gas.
Also read the manual for how much power each burner has.
Curious how taking 20 minutes for a pot of water to boil could be “gross incompetence”.
