With the Tefal Instant Hot Water BR3508, you can choose how much water you need. You can adjust the quantity using 4 settings, preventing you from boiling too much or too little water. You can choose from 6 temperature settings, so you can use the right temperature for every hot drink. This is useful if you prefer green tea to be less hot than black tea, for example. The casing remains cool while boiling, so you can touch the exterior even right after boiling. This makes this water dispenser extra safe to use. The kettle is ready to use quickly, so you won't have to wait long before making tea.
