I recall talking about ceiling mounted radiators? Easier to retrofit and don't get covered up by furniture.
Yes, likely easier to install. Another option is to install thin heating tubes in the walls embedded within the plaster.

Going back to the older way of having walls radiating heat into the house.
You'd want to do this work at the same time as the other walls are being stripped for insulation I expect. I wonder if you could repurpose the underfloor heating kits to do it?

The video at the link below is about an innovative drilling technique that might be of interest to someone thinking about ground level heat pumps. The invention is to use an "inchworm" technique to bore through the regolith.

Costs ** should ** be less than if traditional long pipe drilling is used.
This method might even work on Mars, with a bit of adaptation.
Pretty clever. Swiss, of course.

It is a misconception that a heat pump is gaining enrgy from the earth as heat rather its using the loop to when producing heat the ground loop is sinking cold. when the air condition is on a blowing cold into the home it is sinking heat to the colder earth.
In the winter, a ground loop heat pump cycle draws low-grade heat from the earth. A fluid circulates through underground pipes, absorbing the ground's natural heat. This warm fluid transfers its heat to a refrigerant in the heat pump, which then becomes a very hot gas after being pressurized. A reversing valve sends this hot gas to an indoor heat exchanger, where the heat is released into the home's air distribution system.
Step-by-step cycle
Heat absorption:
In winter, an antifreeze fluid is pumped through the underground loop, absorbing the low-grade heat from the earth, which is warmer than the outside air.Heat transfer:
The warm fluid returns to the heat pump and transfers its heat to a refrigerant through a heat exchanger.
Compression: The refrigerant is then compressed, which significantly increases its temperature.Heat distribution:
A reversing valve directs the superheated refrigerant to an indoor heat exchanger coil. Here, the heat is transferred to the air, which is then circulated throughout the home via ductwork.Refrigerant expansion:
The refrigerant, now cooler, passes through an expansion device, drastically lowering its temperature and pressure.Cycle repeat:
The now cold refrigerant returns to the ground loop heat exchanger, ready to absorb more heat from the ground and repeat the cycle.
