Default Heatpump efficiency/reuse

Hi. Can anyone comment on what improvements have allowed heatpumps to become more efficient ? Older ones were delivering maybe 3x electric power, while newer ones are > 5x. I live on a boat in a tidal harbour, and am thinking of building a water to water pump to store heat when the tide is in. Is it worth extracting the pumps from the old systems, they have had minimal use.

Thanks in advance.
