Total amount of heat for the entire closed system does not increase over 100% of energy used to drive the heat pump. Like you said, you just moved heat around

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
