Very expensive mod to zone off this one room from the rest of the house.

It would cost, but can be done quite cheaply.

Maybe at installation time, but pretty expensive afterwards. If you're
paying for labour.

Portable heating would add cost too, mainly in greater fuel cost.

Capital cost are low.


And a normal boiler might run at reduced efficiency when just heating
one small room.

not by much

We don't know what boiler the OP has. Older ones can be horribly
inefficient when working at a small part of capacity.
