Terra cotta pots concentrate heat using the convection method. Although you can’t warm a whole house with it, this method can definitely help keep you warm and make a cold night much more bearable. When you have several of these going at the same time, that can help keep the room at a comfortable temperature. You can purchase one of these from Heatstick.com and see just how they work. Or if you’re on a tight budget, you can DIY it at a lesser cost.
Radiate the Heat in Your Room with Terra Cotta Pots
- Three small unglazed terra cotta clay pots that range from large to small, i.e. ( 6”, 4”, 2”)
- Saucer Plate
- 6-inch carriage steel bolt
- Washers in varying sizes that fit in the bottom of the pots
- Several nuts to act as spacers between each pot
- Metal stand to hold the radiator ( oil burners work quite well )
- Electric drill
- Mason bit ( same size or slightly larger than the bolt )
Step 1. Drill Center Hole
Drill a hole in the center of the bottom part of each pot (be careful as too much pressure will shatter them).
Step 2. Insert Bolt in Largest Pot
Place the bolt through the hole in the largest pot with the head of the bolt on the outside.
Step 3. Washer on Bolt
Turn the pot upside down and slide a washer over the bolt.
Step 4. Medium Pot Inside
Place the medium pot inside the large pot.
Step 5. Secure Medium Pot
Slide a washer inside the medium pot.
Step 6. Secure the Nuts
Thread two nuts onto the bolt followed by another washer.
Step 7. Place Final Pot
Place the final pot on the bolt. This center pot sticks a little further out so that the heat will radiate to the other clays and out.
Step 8. Place Saucer
Finish with one last washer and nut, and then secure a saucer on top.
Step 9. Furnace Cement for Saucer Plate
Since the carriage bolt kinda sticks out from the top, a permanent fix with a furnace cement can fix it, before sealing the top with a saucer. Just take a bit of the furnace cement and apply it on top of the pot. You may add a bit of water to thin it out.
Step 10. Let Dry
Once you’ve applied an even amount of the cement for a permanent adherence on to the top of the pot, place the saucer on the top for the final step and let dry.
Now simply set it on your stand and place a candle under it.
Keep in mind that 4.25oz standard glass jar candles work the best and never use a pillar candle as it will melt and cause a huge mess.
