Think of it as a water boiling thermos.&lt;p&gt;You’re meant to replace the water daily. Not sure how many follow that guideline.&lt;p&gt;ETA: Only the so-called “hybrid” models have vacuum insulation. It’s worth the extra charge.</text><parent_chain><item><author>mhandley</author><text>According to Twinings tea:&lt;p&gt;&lt;i&gt;Always use freshly drawn (filtered if possible) cold water in the kettle.
