  • The mug warmer works just like an electric kettle where the heating coil helps in heating the mug and transfers warmth to the beverage / food. Simple science of heat transfer happens here, where the thermal energy is converted into kinetic energy and is transferred to the cold objects.
  • Heat always transferred from a higher temperature to a lower temperature and thus the cold coffee gets heated. The heat is even felt while touching the hot coffee cup as the heat is transferred to our hand through the concept called conduction. The mug warmer transfers the heat to the cup placed on it thereby heating the coffee making it warm to drink.

The heat transferred to the cup heats the liquid containing inside it and makes it warm enough to drink. This simple concept is used in the mug warmer making it handy and easy to operate. You get a hot cup of your favorite beverage just by switching the button on and heating it within few minutes.
