Many of these "reduced cost heating" scenarios all presume the person is basically sitting still in a single room. The IR heating might be able to direct the heat in a more concentrated area, but then if you move to another area, it's going to be colder.
A more practical scenario might be to have a general heat source that heats the entire to room to something like 60 degrees, and then a secondary heat source, like an IR unit, an electric blanket, etc. that heats the person to 70 (or whatever).
