The mini clay pot heater works off of candle power. I used one years ago to take the chill off a small office I had out in the barn. They won't heat a large space, but they will make a cold small room comfortable to be in. If my office had had insulated walls and ceiling, it would have been even warmer.
My clay pot heater had 3, or was it 4, pots nested inside one another. There was a bolt running down through the pots' center hole and spacers that kept the pots separated by about 1/8 to 1/4 inch, and the nut & bolt held the contraption together. I didn't make the thing, so I'm not exactly sure of the spacing. The outmost pot had little legs that held it up above table level, and they fit inside of a larger diameter ceramic saucer.
To operate it, i lifted the pots and placed a candle on the center of the saucer. Then lit the candle, then replaced the pots atop the lit candle. It took several minutes before it started giving out heat, I guess because it was heating all those nested pots. But once it started putting out warmth, it felt nice.
A candle by itself sends it's heat to the ceiling. But when it heats those nested clay pots, it radiates into the room space. I don't know how came up with the idea, but it's nifty.
It's never too late to start! I retired to homestead on the slopes of Mauna Loa, an active volcano. I relate snippets of my endeavor on my blog : www.kaufarmer.blogspot.com
We've torn the Love Shack apart for some much needed improvements.
- Added a window
- Added multiple corner braces in the framing for support
- Attached a loose wall frame to the flooring
- Added house wrap to the exterior
- Added horizontal braces to the attic area to enclose it for more warmth retention and critter prevention
- Lapped the exterior siding
