Increasing your water heater temperature by just 10ÂºF from 130ÂºF to 140ÂºF may increase heat loss resulting in a larger electric bill from $30 to $75 dollars annually. Setting the temperature to 140ÂºF can also increase demand losses resulting in an annual expense of up to $500 dollars.

As you said, it's true that breaking bonds always absorbs energy. But breaking bonds is just halfway through for a chemical reaction. Forming new ones releases energy. The difference within determines a chemical reaction endothermic or exothermic. For ATP hydrolysis, the bonds within an ATP and a water molecule break, which absorbs energy, as you might think. Then the new bonds formation to form an ADP and a phosphate releases a lot of energy.
