how do coffee machines heat water so fast?
In: Physics
As others have said most heat a tiny bit at a time
The Bunn brand (and maybe others). Are frequently seen in restaurants, (they also make home units) and actually have a hot water tank, so there’s an entire pot (or more) of hot water ready to go, when you pour the cold water in, it pushes the hot out, then heats the new water for your next pot.
