This is a slinky for a ground sourced heat pump, made from a concrete block.
Would this work?

No. That is a link to a forum on Heat Pumps.

Concrete isnt a good conductor of heat.
Its good for storing heat so if you heat it up during the day it will
retain the heat into the night.
This application however doesnt seem to be doing that so I cant really
see what the benefit is.
Ultimately the greater the capture area of the heat source, the better
the system will work.

My sentiments too. If the slinkies were around the garden in the usual way,
collecting heat from the ground, and this was used to store heat then I
could understand it. IT appears to be the "collector".  I would be
interested to see figures on how this operated.

If I was using a heat store.  I would have a large water tank with slinkies
and a pump, pumping heat from the ground into the tank. Then the heat pump
would extract heat from the tank. Water stores about 3 times as much heat as
masonry.  Using concrete would need to have a large lump of the stuff in the
ground with plastic pipes running through, and probably insulated around it
too.  It would probably need two loop. One to pump heat from the ground into
the concrete, or water tank, and another for the heat pump from the concrete
or water tank. Then the ground does not freeze up.
