We switched to an externally mounted tankless when our big ole water heater conked out. It's way more energy efficient, but everyone has to run the water for a good minute until it kicks in and makes it through the pipes
I'll look into a heat pump once this one dies, but running water during a drought is just wrong.
This Old House has episodes where they have a small recirculation pump to keep lines primed with warm water.
This kills the efficiency gain of not keeping a hot tank though.
