Its pretty funny reading some of these...

For power calcs use Ohm's law. 800W is 800W! The reason most hair dryers are limited to less than 1800W is because 120V/1800W = 15A. Most household 120V circuits are limited to 15A, and will nuisance trip at 13.5-14A depending on circuit load. You can have a dedicated 120V/20A circuit but they are pretty rare in a home and will nuisance trip at anything over 18A.

A 120V/1200W heater of any kind will pull 10A.

All of the electric heaters discussed here are convection heaters. They use electricity to heat air, and they will all heat a room slowly. The marketing geniuses just push "how" the devices use the electricity to heat the air.
