Is the Breville BKE820XL worth the premium over a basic kettle?
Only if you use its settings. A basic kettle boils water just as well; what you pay for here is five one-touch settings for different teas and French press coffee, a 20-minute keep-warm and a soft top lid. If you brew several kinds of tea daily, the kettle earns its place over years of use, while anyone who only needs boiling water for instant meals will not get value from the extras.
What temperatures do the 5 preset settings actually heat to?
Breville labels the five settings by drink rather than by degree: black, green, white and oolong tea, and French press coffee. The instruction booklet in the box explains each one, and the settings are accurate in practice, landing within a couple of percent of target when checked with a thermometer. The practical point is that you choose the drink and the kettle does the rest; if you want a temperature between two settings, you pick the nearer one.
How long does the keep-warm function hold your water temperature?
Up to 20 minutes at whichever setting you selected, according to Breville. That is long enough for a second cup, or to brew a second pot of a different tea, without reheating water you did not pour right away. The hold is time-limited, so the kettle does not keep heating indefinitely; after the window it stops on its own.
Can I wash the Breville BKE820XL jug in the dishwasher?
No. Breville's care instruction is hand wash only. The jug is brushed stainless steel and described as resistant to rust and stains, but that is a property of the metal over time, not a dishwasher endorsement, and the two are not the same thing. Stick to hand washing, and keep water away from the base and the buttons.
How much water does this kettle actually hold?
1.8 litres, which Breville also gives as 57 ounces and 7 cups. The unit itself weighs 3.4 pounds and measures 9.06 inches long by 7.2 inches wide by 9.84 inches tall, so it is worth checking that footprint against your counter or cabinet space before buying. The water sits in a cordless jug that lifts off its base, so once it has heated you can carry the full jug to the table or across the kitchen rather than pouring near an outlet or a live cord.
Is it reliable over the long term?
Largely, yes. Many of these kettles have given years of daily use for different teas. The faults that do appear are with individual units: a kettle that may not always switch off promptly on the full boil setting, or a lid that does not close evenly. Keeping the base and buttons dry, descaling regularly and registering the 1-year replacement warranty are the sensible precautions.
