Hi everybody, I recently got hooked on loose teas (thanks to the Kevin Rose Samovar Tea video) and need help with choosing a kettle/water boiler. I want to start brewing Gong Fu style in my bedroom (that's were I usually drink my tea). I was thinking about getting a Zojirushi water warmer/boiler and then dispensing the water into a ceramic or cast iron teapot to stay hot until use. Is that an OK idea, or will the water cool quickly? I want to get into Oolongs, Pu Erhs, and Greens. Is there an electric kettle that's better suited for this? Do they make stove top kettles with temp gauges?
