That was my dream-home.
A single compressor (well, and another one as backup) and lot of condensers/evaporators and even lot of valves.
Take heat from you don't want it and put it where you want, depending on season.
Fridge, freezer, water heater, space heater/cooler, and two big tankers, one for hot water and one for cold one, as seasonal thermal battery; everything connected by the same heat pump circuit.
But.
But I'm not rich, so:
