I live in the US and I heat my tea water in an electric kettle. It probably isn’t as fast as yours, but it is still close to microwave speed. And I can heat up enough for several cups of tea and have it keep the rest hot. I usually drink more than one at a sitting.
My microwave can boil a single cup of water faster than my kettle. My kettle can boil four cups of water a lot faster than my microwave. It all depends on the microwave and kettle (and the voltage available).
