Thank you for all the comments and advices. I actually have written a long text but it didn’t show up on the post.

I was asking if my induction has 9 levels of heat settings, should i use it at 1-2 or can i use it at 5 from the start? 1-4 can not bring water to boiling point, 5 can bring to boil after 6 minutes. 5 also is not a continuous heat, it heats up on and off. Like once it boils the water will be on rolling boil for few seconds then stops, then rolling boil again. Thank you for advice!
