The four temperature settings use just enough power to boil water for different herbal teas or coffee. It doesn’t matter which water temperature you pick, the kettle will boil the water quickly and save you time.

The keep-warm button is happy to keep the water cosy for 30 minutes afterwards. This is perfect for those who love a second cup or want to leave the water ready for someone else. This kettle is also cordless, quiet, and has a double-walled casing that keeps the body cool to the touch.

  • Cordless.
  • 1.5 liter capacity.
  • The water level is easy to read.

Your Kettle Buying Guide

Buying your first temperature kettle is exciting. But don’t make the mistake of taking the first electric kettle you see because it looks good. Instead of enjoying years of the best tea you’ve ever made, there will be nothing but frustration. Here are the best tips to help you find a kettle that will please your taste buds, wallet, and time.

Consider Your Needs

Variable Temperature Kettle Buying Guide

Do you drink different types of tea daily or occasionally? Do you want to buy an electric kettle for you and your spouse or the office meetings? Not all situations are served by the same product.

For example, if you drink black tea and green tea every day, you’re better off buying one with a narrower temperature control than one with fewer increments. Similarly, a kettle with a larger water capacity will suit the office better.

Another important thing to consider is the product’s user-friendliness. People looking for simplicity should choose kettles with one-touch controls. Those who love technology can opt for smart WiFi kettles. Other things to consider is weight, noise, and safety features.

The Kettle’s Location

At first, it seems strange to consider the kettle’s ultimate location before buying it. But here’s the deal. Kitchen counter space is limited.

Most people also want a new appliance to blend in. Take a few minutes to gauge what size kettle will look good and where. Once you find the perfect spot, look at the surroundings to pick a color that will add flair to the room.

Stay Away From Cheap-Looking Materials

A variable temperature kettle must have quality parts. If possible, view the product in person. When that’s not possible, view images from different sources and read the reviews to see what failed and why. A cheaply produced kettle is often dangerous to use or break within months.

Look For Customer Support

Variable Temperature Kettle Buying Guide

Even the best temperature kettle can malfunction. Good brands will offer a guarantee and advertise the fact with the product description. At the end of the day, nobody wants to sit with a broken kettle that had no warranty.

Looking for a guarantee is actually the best tip to keep in mind before you buy any appliance.

As for your temperature kettle, when you have the reassurance of a warranty, you can sit back and enjoy your tea kettle knowing that if something goes wrong, there’s a replacement waiting free of charge.


Q: What Temperature Does a Kettle Boil At?

A: The temperature a kettle boils at isn’t a single number. It depends on atmospheric pressure.

In other words, if you live at sea level, then a kettle might boil at 100 degrees Celsius. The boiling point of water for higher altitudes is roughly around 93 degrees Celsius. Needless to say, this doesn’t hold true for a variable temperature kettle that boils at the temperature chosen by its owner which could be any variable below 93 degrees.

Q: Are Glass Kettles Safe?

A: Glass kettles are safe when produced by a trusted brand. You might be comforted to know that, while glass kettles appear fragile, they are anything but flimsy. Their materials are treated to deal with damages, time, and temperature.

Q: Is A Stainless Steel Kettle Safe?

A: A stainless steel kettle is safe when you buy the right one. On the bright side, all stainless steel kettles share a good trait with glass. Nothing bad leeches from the steel into the water, so tea made with this kettle should be safe to consume.

The main problem is the single-walled designs. As the temperature peaks, these kettles get really hot. For this reason, when looking to buy an electric kettle from the shiny department, make sure that you pick a double-walled brand (these appliances keep a cool exterior even when the water temperature is high).
