This was somewhat one of those Covid projects that got a fair amount of use last winter in Arizona because we could at least be a little bit social by always staying outside. I try lots of things that do not work but this one seemed a good thing so I spent the time to document what I measured. Might be interesting, might not be.. but it is December after all and the sailing subject is a bit limited for most. Anyhow.. I will take the risk that this ends up being a discussion about home insurance (yep.. I know). Black body radiation is part of the discussion and is interesting just by itself.
One discussion we have had so far is would there be a benefit if the shield in the link was thicker metal. I dont think so.

Edit Jan 19.. I both modified the shield and did a much more accurate measurement of the radiated power. In this thread, I had over estimated the radiated power for the Propane heater on its lowest setting but it still ends up being about 733 watts.
