Recently installed a bunch of incandescent bulbs because I had them at the bottom of a drawer.
I was surprised how the small amount of infrared from them makes rooms feel more pleasant to be in. It's a warmth on the skin, rather like having a fireplace going.
If I weren't paying the electricity bill, I would totally fit them everywhere.
This sensation of warmth while being in a nominally cold room can also be created with microwaves. A couple of such systems were designed when microwaves were the new hotness. Turns out it might cause cataracts, though.
100W of heat is like having another person in the room.
It's nothing at all like having a fireplace going - unless they're on fire, in which case both of you have a problem.
