Boiling water is a fixed temperature at a given air pressure. Turning up the heat doesn’t make the water hotter. You just lose it faster. If you need higher temperatures and are cooking in boiling water, then you have to use a pressure cooker.
Who said anything about turning the heat UP?
I meant up relative to the boiling point. Since the boiling point is lower, the same heat output is relatively higher. It just boils the water faster and does nothing to the temperature. You just need enough heat to get it to a boil if you don’t want to waste extra water and heat.
