Electric kettle/hot pot that warms, but doesn't boil

In My Humble Opinion
19

  1. I don’t want to increase the number of devices involved, so adding a thermos to the sequence isn’t in the cards

  2. I don’t want the water to boil at all. I want it to teach a designated temperature and stay there. Currently I have to monitor the temperature of the water with a stick thermometer. I want to eliminate that step and just have the warming device to it automatically.
