We have been using them as a way of saving on heating bills for years. One or two bottles can save you a load of money and fuel as you dont need the fires on so much

And they are ideal for all of you envisage bugging out to your abandoned building(s) or roughing it on the moors when tshtf. You might not be able to have a fire to keep you warm due to the risk of being noticed but you could boil a pint of water in 5 mins on your Hex Stove, fill up the bottle, and that will keep you warm for hours

Hot Water Bottles should be a staple item in every preppers kit imo
