And no, the microwave is not a valid option.

I've had microwaved water for tea a few times.

For some reason the water always starts foaming up a little bit when it's from a microwave instead of a normal kettle. I don't know why or what the difference is, but I prefer non-foamy water.

    Water foaming when heated is caused by impurities in the water rather than the heating mechanism. So whatever is causing your water to foam is in it either way

    And yet I never see it when I use a kettle.
