    Sometimes there is usually there isn’t.

    The trap is that often times when there is a performance difference, a change in behavior can accommodate fairly reasonably.

    For example, a hybrid hot water heater in its most efficient mode will (sometimes) recover heat slower than a pure electric or gas heater. That generally only matters for showers, so a shorter shower can overcome the slower recovery.
