You have to consider drop in humidity too for the comfort breathing.. other wise anybody can use ceramic heater which are more efficient than infrared.
Awesome dude, I was looking for this data without buying. For everyone out there, in order to have a true efficient low watt cost heater, High output is a must with low watt used, based on your data Dr. Heater is a huge Failure, it will cost to much to run vs HomeComfort, would never use. My Lasko Heaters 10 years old as an example, Air Heat output @200 with a watts off 1300. Cheaper to run and buy, then Dr Heater and most in the market today, Ty.
