Clay Pot Heaters are comprised of four or more clay planting pots separated by washers and nuts forming a multilayered unit.
The idea behind these heaters is heat absorption then dispersion via radiant heat. The space between the pots captures the heat of the candles which then heats up the clay. The clay then radiates this stored heat into the surrounding air.
I have watched several YouTube videos of this heater and found myself compelled to test the idea out.
This post highlights my conclusion about the viability of the so called "Clay Pot Heater."
