I don't like cold tea (when it's supposed to be hot). Actually, I'm luke-warm toward iced tea, too.
Here's how I keep my tea hot. It works tremendously well! It's a teapot warmer and you can find them at various tea stores and with a simple search online. I'm using a beeswax candle below because I don't like to burn the petro (regular) kind - especially near food.
Another tip: Use a small cup and pour out only a little tea at a time.
