    For a single mug microwaves are quicker in America. Potentially even for 2 mugs.

    BUT in America kitchen appliances have a power limit (usually) of 1,500W. This is usually higher than a standard microwave (1,000W). And since an electric kettle in America is just a heat source in water, it’s very efficient. So if you’re regularly heating multiple mugs worth of water, or just boiling water for cooking often, an electric kettle is definitely better. They are also pretty cheap.

    Now in Europe and the UK, electric kettles are faster since they can often be around 3,000W or higher. But that doesn’t mean American kettles are useless. American kettles a way faster than heating water on the stove. And WAAAY faster than heating water on a gas stove.

      I love my electric kettle. I can get 5 cups of boiling water in about five minutes (less for less water).

      And while a microwave is likely faster, it also heats the container. For a quick, single mug, it’s not an issue. Run that thing for five to heat a lot of water, and the container itself could be scorching hot.

      I prefer the kettle every time.

      Why wouldn’t a microwave in the UK also be 3000W? Maybe it would instantly vaporize water and kill you when you open it?

      It sounds like the issue is that UK may have weak microwaves compared to their kettles.

        It would burn your food. Microwaves heat the outermost layer that contains water. That heat conducts inwards. It’s the same reason you don’t bake everything at 500F.

        They absolutely do. Many microwaves in the UK are about half the power of built in American microwaves. (Portable/countertop microwaves are extremely common, being around 700-800W usually)

    Kettle is much more convenient. Microwave is overkill, while a kettle is both a simpler machine and turns itself off when the water boils with no guesswork. It’s ergonomically designed for pouring into a cup.

    The speed argument is irrelevant, they’re both quick enough.

        American kettles are significantly worse than British kettles. They run at lower voltage and lower amperage, so they take much longer to boil water.

        Given the choice between using a multipurpose microwave to do one more thing, and buying a separate appliance that is no faster, choosing to use the device you already own is entirely appropriate.

          If you drink tea or coffee, even irregularly, a kettle is worth having.

          And a pour over is better than Keurig crap. I’d recommend using paper filters as well. Most of the time I just rinse the pour over when finished.

          Generally I grind 2-3 servings of beans at a time and store the rest in a glass container in the fridge.

          In the end, the effort is pretty comparable to a Keurig machine, but better quality, more flexibility, and you don’t have to deal with/buy pods or a machine.

          They are still the best option for heating water. At best, a microwave could match its performance if it is nearly perfectly efficient and dumping all it’s energy only into the water, which is what a kettle does. They have the same potential power draw, so they can put the same energy in as each other. A kettle’s design is perfect for heating water though.

          Unless you have an inductive stove top, an electric kettle is going to be the best option, even in the US. It’s the most efficient at putting energy into the water and, since all these options have the same power draw, it is consequently the fastest (again, assuming no inductive stove top which can draw more power).

        There’s also the whole “kettles in America take longer to heat up, because America only has 120v electrical outlets while the UK has 240v, and therefore gets twice as much power for the same amperage” thing. That being said, I’m in America and I love my kettle. You just expect it to take 5-7 minutes to heat up, instead of 2-3. If I only want a single cup of something, then yeah I’ll use the microwave. But if I’m going to be making more than one cup, the kettle is my go-to.

        No judgement from me towards anyone who uses a microwave like this. But that’s not a good argument. If you want to get pedantic, the one-time inconvenience of going to the store will be made up for by the hundreds of small conveniences of using it later.

        In general I don’t think it’s fair to think about the inconvenience of buying a thing. Even online reviews, which often complain about shipping times which has nothing to do with the product, don’t really complain about the inconvenience of having to buy or order something. It’s not relevant.

      The microwave is more efficient because you can do all the steps at once. Put teabag in mug, cover with water, microwave, leave and let steep. And if you forget about your tea it’s already in the microwave – just push the “add 30 seconds” button.

      I keep my Splenda and non-dairy creamer next to the microwave for added convenience.

        Because resistive heating is inefficient. You need to pump a lot of power through to get a lot of heat. A microwave does not use resistive heating and works on a completely different principle and therefore the amount of power available is much less importance.

          Resistive heating is almost perfectly efficient. Where else would the energy go? Using a hot piece of metal to heat water might be slower than using microwave radiation, but that’s a different kettle of fish.

            Yes all the energy goes into being heat but you have to put a lot of energy into the wire before it heats up. Microwaves barely use any energy in fact it takes more power to run the little clock than the microwave itself.

              That’s insanely untrue. Microwaves are power hogs up to a 1000 watts or more in some cases. The difference is the heat transmission method. The conduction of heat in a kettle is pretty slow because it forces the heat to propagate through water via convection, which is slower, while the radiation of a microwave antenna distributes the energy more evenly and faster. Consumption is mostly on par but energy transfer differs.

            Yeah, but not for countertop appliances. Those are all 110/120VAC. Even things as large as a consumer level refrigerator or freezer are almost always 110/120VAC too.

            While I have a kettle for water, there are two issues with them for tea.

            1. The water gets stale and the reheating drives off the all the excess air that fresh water has. This loss of dissolved oxygen kills the flavor of your tea and makes it taste bad. You should always use fresh water to make your or even coffee.
            2. A cheap kettle is, well cheap. You can’t make a good cup of green or oolong tea if you pour boiling water on it. Those need to be brewed at a lower temperature. And guessing doesn’t work. And a temperature adjustable kettle will set you back anywhere from $50US to $100US.

        They use different methods of putting heat into water.

        A microwave turns the electricity into RF radiation that is absorbed by the water. To produce that radiation, the input electricity is converted to thousands of volts by a DC power supply. So regardless of whether it’s 120 or 230 input voltage, it all gets converted to the same high voltage DC to run the magnetron.

        A classic electric kettle works by running the current from the outlet through a resistive heating element. Double voltage means double heat.

        Induction heaters use a power supply to reduce the input voltage while increasing amps and frequency to heat metal through inductance. So, similar to a microwave, the voltage of the outlet is largely irrelevant.

        Tl;Dr: microwaves and induction heaters change the supplied voltage to function, so they work the same in UK and US; resistive heaters work faster on 230v like the UK uses.

        No my point is, as a British person that uses the kettle A LOT we went out and bought one that heats up a single cup at a time, which is quicker than boiling a whole kettle.

        I fill it up like a kettle and it has a little chamber underneath that it fills and heats, then the boiling water comes out of a spout into the cup.

        After owning this type of kettle for over a decade I don’t think I can go back to a conventional kettle.

    There are very good reasons not to microwave tea, first of all:

    • I usually find microwaving anything in a mug adds some unpleasant flavour from the mug. Using glass eliminates this, but worth noting.

    • Microwaving the tea itself will break down some compounds and release more tannins, your tea will be worse.

    But even if you’re just microwaving the water, the kettle wins (depending on what tea you are brewing). Black tea should be brewed as close as possible to 100°C - when you have a kettle you should pour it just as it comes off the boil, around 90-95°C. By that point the water has actually been boiling for quite a while (at least the water around the element), allowing the rest of it to heat up. It’s very difficult to achieve this in a microwave, and dangerous too since you can just end up spraying boiling water around your microwave.

        Don’t the microwaves keep reflecting off of the inside of the microwaves until they hit a water molecule? If they didn’t, the inside of the microwave would heat up along with the water.
