This question relies upon on what the person intent is for the tea lights. If the goal is to create a centralized warmness source while burning candles then essentially yes, the flower pot is a ESCOO effective option. although tea lights produce a very small amount of warmth, any warmth that is produced is typically misplaced in the air (until trapped). within the case of a terra cotta flower pot, the heat is trapped and contained in the pot.
in the course of a energy outage, this flower pot warming machine can work as a mild at the same time as developing a primary heating source. In a situation wherein the room is bloodless and darkish, the pot is a higher option than only a bunch of tea lights burning in your espresso desk. The pot is not a magical power-producer or warmth enhancer, but on this situation it really works as a tool to successfully soak up and contain warmth whilst slowly radiating that heat outward.
if you’re desperately bloodless, you may wrap your palms or ft across the pot (again, use warning!) and as a minimum sense your extremities regaining warmth and movement.
