Just got a convection style one a few days ago and love it! Why doesn't everyone use these? It's super cheap if you use clean diesel with a little alcohol mixed in instead of Kerosene and heats a whole room up in minutes. I understand CO poisoning risks but like any other souce of heat that requires gas or burning something just use common sense and crack a window open. You can even get an alarm/monitor for $20 these days. I'm just curious why nobody in the US seems to use these anymore. I love mine!
