  Most of the propane heater is a fan in a tube, the flame is probably quite smaller than a CPU package.

    I've got an 8kW wood stove and that thing gets rather hot to touch - as in, you will get a blister... 40kW is a small city car worth of power.

      If you think about it, cars can manage cooling 200+kW with a radiator - and a lot of airflow. That's still an amazing amount of power though. I can't help thinking about the kind of sear you could get on a steak with 40kW of power :D
