For real. Everytime I get in the shower I end up having to point the showerhead away and cower from the cold water and I could have just turned it on first?

Sorry, you’ve met wealthy people, right…?
It’s just dumb engineering to heat up a pipe the entire day for the 0.8% of the day you need it to be hot.
With enough insulation, anything can meet energy-efficiency standards. XD

Have you read the previous comments? Because that’s exactly what’s implied.
Heat pumps generally use a lot less power. Don’t need to heat up much if it is already slightly hot.
It’s typically used for large complexes like campuses where the hot water is made en masse in one building and the loop goes around all the other buildings. Helps keep cost down (at construction) because you only need one giant water heater. Helps not have to wait 10 minutes to bring the hot water to your building. Energy still gets wasted but given the number of users, not that bad.
In modern ones they learn patterns about hot water usage, so they are only active on max during the “busy” periods.
