We have for many years had an electric blanket, but my hubby is going back in time when we used to have hot water bottles, l always keep 2 for when we need one, as a conforter when feeling poorly, hubby has now decided he wants a hot water bottle to take to bed. I took electric blanket off bed as water and electric does not mix, hubby takes 30mins to fill 2 bottles, l have watched him tonight, as we have glass in kitchen door, he runs the hot water tap, thinking that hots the electric kettle, so after a while no hot water in tank or kettle, l tried to tell him he needs to put water in the kettle to hot the water, not to run the hot water tap, he got very cross as l was interfering which his project, l think l should throw the bottles away, but will he get more cross when he can not find them, any advice, please help me
