At work, I currently have two options for hot water for my tea:

* Getting hot water directly from the side of the coffee maker. It is
difficult to tell how hot this water is, since I do not have a
thermometer. It is not boiling, so my best guess would be 160 - 175. I
have verified that this water is filtered.

* Getting cool water from our filtered tap and microwaving it.

One of these days I will invest in a kettle, but in the meantime I
have to deal with one of these two options. #1 is obviously more
convenient for me. I was wondering if #2 would be that much better. I
know microwaving water makes it taste flat... so does it not even
matter? The advantage of #2 is that I would have more control over the
temperature.

Thanks.
