The Still hot Illumination found on some Breville kettles is a unique feature that tells you when the water is still at a temperature suitable for tea and coffee, preventing the need to re-boil your kettle and waste energy.

As the water in a Still Hot jug kettle boils, the internal illumination turns from blue to red. Once the kettle has finished boiling, the internal illumination will remain red until the termperature of the water drops below 80 degrees, the perfect temperature to drink tee and coffee.
