Why so long for just a gallon. You can boil out a gallon of water in about 70 minutes on a regular home stove.

- calfuris 3y agoElectric stoves get dedicated high-power circuits, these things plug into a regular wall socket. They just don't have the same power.
- thrdbndndn 3y agoDo you mean 7 minutes? Taking 70 min to boil only 1 Gal of water sounds extremely long.
- nayuki 3y agoIt takes way more heat to change liquid water to a gas than to bring liquid water from 0 °C to 100 °C. > the molecules in liquid water are held together by relatively strong hydrogen bonds, and its enthalpy of vaporization, 40.65 kJ/mol, is more than five times the energy required to heat the same quantity of water from 0 °C to 100 °C -- https://en.wikipedia.org/wiki/Enthalpy_of_vaporization#Thermodynamic_background https://en.wikipedia.org/wiki/Enthalpy_of_vaporization#Therm...
- thrdbndndn 3y agoOh thanks. I'm aware of that, but I didn't realize "boil out" (turning all to stream) means something different from "boil" (to just heat to reach boil point or rolling boil).
