Is it frickin’ freezing where you are? We are just pulling out of our cold snap and might even see 0F.  Sunday’s high was -21F and yesterday we spiked the thermometer at -10F and it almost felt warm.

At -10F, the house heaters are able to keep up just fine, especially with the sun shining during the day.  But when it gets colder than that and there is wind, it can get chilly in the house.  I saw this little trick a few weeks back and thought we’d give it a shot.

I am amazed at how well it actually works.

Of course since we are dealing with fire, it’s uber important to make sure kids understand the danger and that you put the heater in a safe place, out of reach of small hands.  These can get quite hot pretty quickly.

These heaters can lead to a great discussion about heat conduction.

This video is a great tutorial on how to put one together.

It’s very simple to put together and can be done a few different ways.  The first version I saw didn’t bother with nuts and bolts and simply stacked 2 pots on top of a couple bricks over a few candles.  Easy peasy. We opted to bolt them all together after experimenting with the simple version just to make it easier to move.


  • 10″ diameter clay flower pot
  • 8″ diameter clay flower pot
  • 6″ diameter clay flower pot (optional)
  • one 4-5″ long 3/4″ bolt
  • three bolts, 3/4″
  • 3 washers, 3/4″, must be bigger than the whole in the bottom of your pots

1. Place first nut and washer on the bolt.  Gently put the bolt through the hole in the bottom of the biggest pot.

2. Add the second largest pot and one washer to the bolt. Wind the second nut on the bolt, about an inch or two from the bottom of the second pot.

3. Add the small pot (if using) and one washer to the bolt. Wind the third nut onto the bold, about an inch or two from the bottom and add washer.

4.  Very careful, turn the whole thing over.  The internal pots should be resting on the washers.

Using my mad graphics skilz, the order on the bolt goes:

Place pot onto of something.  Air flow is important.  The candles will extinguish themselves if there isn’t enough air. We used a few different things and found these mason jars worked the best.  Bricks are another great option (I’m planning on grabbing a couple the next time we run to town). We tried a square glass dish as shown in one video we saw but it just didn’t have enough air flow.

You can use simple cheap tealights to power this but you can also use an oil lamp like we did. An oil lamp with fiberglass wicks last much longer than tea lights.  Here are great instructions for making an oil lamp out of a mason jar:

Here is ours all put together.
