One of the variables is the amount of water being boiled. For a given kettle, there is a roughly linear relationship between the mass of the water and the time it takes to heat it by a degree. If I get two kettles, plug them both in, and split the water between them, then don’t I get my water boiled twice as fast? Why can’t we just put two elements in one kettle?
Sure, that’s the BTU right there. You would think that if you had 100 equal elements heating 100 equally sized amounts of water (in a vacuum), that it’d go faster than one element heating one 100 times as large. I imagine you’d need some kind of separation between the elements, or they’d end up hearing one another and affecting their individual efficiencies. I’m sure Lemmy can design a more efficient kettle though, let’s get on it.
