Whilst it’s still cold working from home, I’ll often use a hot water bottle to keep warm. I’m often curious if it’s better to fill it more or less and whether it makes any difference to the bottle staying warm. In consistent and matching conditions, would it make any difference how much water was put in the bottle, and why?

Fantastic! Thanks for the answers. I had an idea that a filler bottle was hotter for longer but didn’t know the science.
