SO
I decided to get a nice tea kettle which has been designed to be able to brew tea inside. I chose this one:

Firstly, it is cast iron which will match my new Iwachu set perfectly. Secondly, the entire top of the kettle is the lid, so removing the brewed leaves and cleaning the kettle will be a sinch! (Much easier than if it was a traditional kettle with a small round hole in the top.
OK
So I finally get to my problem! When I heat my water in the kettle, I will pour a bit into the teapot to preheat it. Theoretically I would then have a kettle of hot water, and some tea. BUT aren't you supposed to pour the water ONTO the tea, and not add the tea TO the water? Im worried that this reversal of sequence might effect my tea negatively.
I tried pouring the water out, and then adding the tea to the kettle, and then adding the water again. Unfortunately this drastically lowers the temperature of the water.
So can anyone give me some ideas/tips? If I took a kettle of water at the appropriate temperature, added the tea and stirred a bit, would that work as well as pouring the water on the tea?
Thanks so much for your help everyone!
