Details on using Instapot to boil water for 10 minutes

Hello. I am currently boiling water in a large pot on my gas stove. It heats up the kitchen and steams things up as it reaches the boil and boils for ten minutes.

I keep reading about people using an Instapot to boil their water. I feel that this is safer and also does not heat up the whole kitchen, but I am confused about the exact directions.

I read that you add water, set to pressure cook, put in the time, and when it reaches pressure, the timing countdown begins. So, when the button pops up, pressure is reached, I let it run for ten minutes, as I had set on the timer, and then it turns off. Pressure can be left to reduce naturally, with the lid closed, or it can be done quickly. Is this correct?

I have also read that people use the sauté setting. How does a sauté setting boil the water? Could anyone please clarify? I would like to not have to turn the gas on high to do all of that boiling and then have to move that boiling pot of water off the stove.

Also, is there a particular brand and size that anyone might recommend as having worked well for them?

Thank you so much for any clarification.
