Thermostatic pots are mostly made of glass, with small capacity, but they can be used as health tea. You can choose according to your own needs. I just use it as a household kettle, so I need a bigger milliliter. This constant temperature pot has a larger capacity, and the constant temperature can be adjusted from 45 degrees every 5 degrees. The water inlet is large. I don't need a water dispenser at home. I just add drinking water to it to 100 and then cool it to 55 degrees.
