Electric Water Heater
The other day, I was making tea for myself in my apartment, and started to think about how the electric water boiler works. Electric water heater, also known as electric dispensing pot, electric water heater, or electric water urn, consumes
electric power to heat up a heating element on the bottom surface of its reservoir, which in turn, boils the water.
What I like about the design is that it boils the water very quickly (I timed it: it takes roughly about 4 minutes to boil 1 L of water from room temperature). I began to think about how it boils it so quickly, and found that the high surface roughness of the
heating element, the material composition of the heating element, as well as the high power rating (3000 W), cause to the water to boil at such fast rate.
However, one problem I see with the design is that the product does not address the needs of the portion of the demographics of the tea drinkers, whom like to prepare the tea with tea concentrates (not tea bags). In other words, a kettle provides the freedom to heat a teapot on top of it, while the electric water boiler does not allow this.
If I were to improve the design of my electric water boiler, I would modify the design such that a tea pot can be heated by situating it on top of the electric water boiler.
