Tea kit

[armormaniac]

I'm going to be moving soon and I would love to make a travel tea kit, I already have everything sorted out except for something to heat the water. A while ago I found something to heat water that was essentially just the coil you would find in a electric kettle. Does anyone know what those are called?

immersion water heater?

That's it! Thanks
