Tea is an essential beverage in countries around the world. From ancient to modern times, from one continent to the next, tea is prized for its stimulating, soothing, or just plain delicious and aromatic qualities.

In a hurry? I like the Secura Double Wall Electric Kettle at Amazon.

We all have probably seen one of those movies where someone comes over to someone’s house and the welcoming friend or family member pats them on the back, and then says the magic words, “I’ll put some water on for tea.” Well, I can tell you that that’s not just a line for the movies. Even as a broke university student living in a shoebox-sized room, the fact that among my scant possessions I had an electric water heater and tea at the ready to offer visitors made many a tough conversation or emotional breakdown just a bit more bearable.

Regardless of why you want to make tea, or with whom you’ll share it, having an electric tea kettle is an essential tool to be able to treat yourself to a cuppa’ anytime you’d like.

What is hard water?

If this was a riddle, you would probably say “ice,” but hard water is actually a term used to describe water with high mineral content – as opposed to soft water, which has low mineral content. Hard water generally has high concentrations of calcium and magnesium carbonates, absorbed when water passes through limestone or chalk deposits.

Hard water = hard times for appliances

Though generally not immediately harmful to people when consumed, hard water does have seriously negative effects on appliances, boilers, coolers, and any other containers or equipment used in the transport and storage of water. Hard water can leave deposits, called “scale,” or “limescale,” of calcium carbonate, magnesium hydroxide, and calcium sulfate. This scale can build up over time, eventually clogging pipes and causing issues with plumbing, or causing boilers to overheat and break down.

Hard water, when mixed with soap, also results in soap producing a white precipitate rather than the normal soapy lather. This precipitate can then remain on metals and other materials, building up over time and causing the equipment to corrode, deteriorate, or become unusable.

For tea kettles, those made of stainless steel, glass, or ceramic tend to hold up best against the effects of hard water.

A brief history of tea kettles

The first tea kettle was, of course, not electric. For centuries, humans around the world have boiled water to remove bacteria and other harmful agents.

Legend has it that tea was first “discovered” around 2737 B.C., one day when the Chinese emperor Shennong was happily drinking a cup of boiled water outdoors, enjoying the view and soaking up some sun. A wind suddenly blew some leaves from a nearby tree into his cup. The Emperor liked the taste and the rest, as they say history.

The first kettles used primarily for boiling water for tea were cast from iron to withstand direct flame from the fire. As time went on, the design of the tea kettle was perfected and other materials – including copper, porcelain, and eventually steel – were used.


It wasn’t until 1891 that the first electric tea kettle was invented by the Carpenter Electric Company in the United States, and in 1922 the Swan Company improved upon the design, making the boil rate much faster. In 1956 Russell Hobbs came out with the first fully automatic electric tea kettle, a model which is still in use today.

Sip away!

The right electric tea kettle is everyone’s cup of tea, so be sure to invest in one that will outlast the effects of hard water and the wear and tear of daily use.
