Have realised that only really use stove to boil water for coffee in the morning and so could probably go without it but could NOT go without my coffee!

I remember some of you have talked about these things that boil water - did a searh but cannot find them. Any idea? I know you do!

my parents hate water that has been boiled and then put in a flask for tea. this could mean freshly boiled water at a picnic?
