What is the best way to heat water fast?
(OP)
What is the best way to heat water fast, like in an instantaneous hot water heater, or a coffee pot? Is it possible to run the water inside of copper tubing that has been heated like the heating element in a dishwasher or oven?

IRstuff is exactly correct. We don't know a lot of things about what you ask. For example, are you dealing with static water or steady-state water flow? I can answer the basic question with the basic truth:
The fastest way to heat water is to sparge live steam directly into it.
However, this may not be acceptable to you. Everything has a trade off and sparging has its own tradeoffs as well. For all I know you may just be trying to warm up a cup of coffee. Nevertheless, I believe my statement to be true.

How do you heat water with induction? Or can you direct me to a source to learn more?
Thank you.

I am trying to heat water in a coffee pot, with electricity, however we want to have as low a temperature as possible at the heating element and still get the water to 180F or so. We thought that running the cold water through the inside of a hollow heating element would work well. Do you think this will work?
RE: What is the best way to heat water fast?
It does not seem like that would be efficient or wise, because:
Only half of your heater element's surface area is contacting the water. You could of course insulate the outside.
The water would be directly in contact with an electrically live surface.
The properties of materials that make good pipes make bad resistance heaters.
RE: What is the best way to heat water fast?
In direct contact with an electrically live surface? I don't understand, then why can you touch an oven heating element without getting shocked? Never mind the scorching burn.

Wire: Conducts electricity and gets hot, as dictated by Ohm's law.
Ceramic, glass or other refractory fill: Selected to be an electrical insulator, but a good conductor of heat.
Outer metal sheath: To provide stiffness and protect the other two components.

You seem to be thinking that you have some sort of killer product, yet you've done nothing or know very little about the problem that you seem to claim to have a solution for.
Or is this for school?

Or, a hotter heater with somewhat less area.
That is probably covered in your textbook.

I think we are back to the basic question: Is it "like a coffee maker" - or are you trying to make a coffee maker?
What is the scale we talking about? A few cups a day or many m3?
Best regards

and later...
If you don't have a tank, where will 1.5 liters of hot water be kept?
Does it seem to anyone else that freedomtech and Watco must be lab partners?
Have you figured out how much energy you need to heat 1.5 l of water 83 degrees C yet? That would be a good place to start.

They've switch to Metric, so I think they would need about a kilogram of red hot iron, not 2 pounds.
However, I think it would make the coffee taste bad.
