BrevilleBTM800XL Tea Maker Infuser and Water Kettle, 51 oz, Brushed Stainless Steel and Glass

Are the plastic components BPA free? Why do you have plastic components?

As of March 2014, I do not see replacement carafes on the Breville site. If the glass breaks, where can I find a new carafe?

Can this tea maker boil hot water like an electric kettle? (Without brewing tea)

Does the type of water you use (tap vs. filtered) seem to impact the life of the product?
