Well, it relies upon a candle. That candle would release its heat into the room even without this gadget.

Does work the same. It's more like like the difference between a camp fire and a rocket stove.

“Steel has the ability to approach the temperature of its heat source,” says the inventor, “so the solid steel inner core will go as high as 550° Fahrenheit. That high inner temperature is mitigated to a very warm 160° to 180° on the outer surface. As long as the candle remains under the steel the surface is constantly emitting dry radiant heat.”

Yeah, I don’t much see the point here. The heat balance isn’t going to change. A candle can only put out so much heat period.

"Well, it relies upon a candle. That candle would release its heat into the room even without this gadget."

This gadget controls the release of the heat. As an analogy, you could take a few gallons of hot water and pump them into an old fashioned radiator...

...or you could simply take all that hot water and pour it on the floor. Which do you think would keep a room warmer?

No, it wouldn’t increase the amount of heat the candle gives off but it should keep the pots warm for a short while after the candle burns out providing a few more minutes of heat for your hands and feet. Much like putting a rock from the campfire by your feet when camping. You get two for one with this contraption and no cost if you have those supplies already.
