It very much can exceed 100% and it’s not a measure invented for click bait purposes.
Look up heat pumps. You can make things hotter by moving heat than you could by directly heating it by burning fuel.
- MrsPeaches 5y agoAs another comment pointed out, it’s usually called the Coefficient of Performance in this case. Which is to say this is click bait, because saying it has a COP of 3.85 isn’t anywhere near as sexy, whilst being technically more accurate.
- stephen_g 5y agoThe ‘more than 100%’ is only in comparison to a less efficient process. A heat pump itself is operating below 100% efficiency - it’s just kind of “cheating” by using an external source of external energy as one of its inputs in addition to the electricity running it.
