It take more energy to pump the water up than what you get when it falls. It
is a standby top cope with peaks.

Just have it heat a large insulated thermal store of water, used for heating
and DHW.

You seem to understand "energy" in thermodynamics. Now go and look up
"enthalpy" and "entropy".

I know exactly what they are.  He can store even low grade heat in a thermal
store and use it for pre-heating DHW.

Exactly what DPs are doing here using solid fuel and solar. They store low
grade heat (could be high grade at times) and use it to pre-heat a combi.
They even use a flue gas heat recovery unit to heat the thermal store too.
