Now that I have a 5kw induction cooktop I can boil water incredibly fast. However I’m not sure it’s that useful since it’s not like I’m standing there watching it, so whether it’s 1 min or 5 min doesn’t matter.
I have a really old infrared range that takes 20+ minutes to boil a pot of water. Believe me when it takes that long it does matter. (it is on the list to replace, but there are higher priorities in this house to fix first, and only limited budget)
