How long does it keep water hot? I need something something that will keep water very hot for at least 12 hours.

I have had this thermos for several years and have 2. I find if you fill the thermos with boiling hot water and secure the lid tight it will keep the water hot for 12 hours and more. It is the only one I found that really works.

This bottle will have only one lid
