DIY Hydronic Floor Heating

As I understand the plate HX's being used they are exchanging heat from water to Refrig to water on roughly a 1:1 volume inside plate HX. Water on both side needs pump to circulate the water. Seeing an advantage for a volume of water "stored" on both sides to buffer temp and cycling of HP I see a HX that could xfer the directly to stored water as a way to elimatet wo pumps. Stored water >(HX?)HP(HX?)> stored water rather than stored water>pump>plateHX>HP>plateHX>stored water. Less parts to loop. Don't know if you have come across diagram of an "open system" for hydronic radiant heating but I think xfering heat into the central tank of this system would be ideal. Might not be a good HX to do that(not moving water).
