Q: Do infrared space heaters actually save money as claimed?
I don't understand infrared heat. Supposedly, a unit like the Dr. Infrared Heater---

---heats up the objects in a room rather than heating the air. Why would I care if the books in my bookcase are warm? Also, these units have a fan, implying that they're heating the air?
They use 1500 watts, same as other electric heaters, so I don't see any savings, unless they use electricity so efficiently that they don't run as often as other types of room heaters.
I'm looking for the cheapest way to heat my office, given that a 1500-watt space heater costs about as much to run per month as an air conditioner.
