Sounds ballpark. The water I use here is quite a bit cooler than 74F at the beginning.

Our groundwater temperature today appears to be about 63F.

So we brought in the outdoor thermometer, and filled the kettle with exactly 1 quart of 74F water. It took 3:15 for full boil, and shut itself off about 8 seconds later.

EDIT: wait a sec.. SWMBO informs me that the measure scale on the kettle is incorrect: we actually just boiled 5.5 cups of water rather than the indicated quart (4 cups). The experiment will have to be run again now. smile

Cheers!
