What is a Clay Pot Heater?
A clay pot heater is a homemade heating device that uses candles or another small heat source to warm up a space.
Here’s how it works: the clay pots absorb heat from the candles and because clay holds heat well it radiates that warmth into the surrounding area.
It’s a simple but effective way to get a little extra heat without electricity.
Why does it work?
- Clay’s properties: Clay retains and distributes heat evenly.
- Small and compact: Uses just a few tealight candles but can make a big difference in a small room.
- Eco-friendly: It doesn’t use electricity, so it’s better for the environment.

But it’s not a miracle worker. A clay pot heater is for small spaces like a bedroom or workspace and is not meant to replace your main heating system.
Always remember to be safe. Never leave it unattended, and make sure it’s on a sturdy, heat resistant surface.
Why Make a Clay Pot Heater?
Let’s get real. Why would you want to make a clay pot heater in the first place? Here are some scenarios where it makes sense:
- You’re on a tight budget. Heating costs add up fast, and a clay pot heater is a cheap alternative to get a little extra warmth.
- You get power outages. Since it doesn’t use electricity, it’s a lifesaver during blackouts.
- You want a portable option. It’s small and easy to move around, perfect for warming up different areas of your home.
- You want to be eco friendly. Using renewable heat sources like candles, it’s a more sustainable option.
Materials to Make a Clay Pot Heater
Before we get started, let’s gather everything we need. The materials are simple and easy to find, which is part of why this is such a great project.
Here’s what you’ll need:
- Two clay pots: Get one small pot and one medium pot. Terra-cotta works best because it holds heat well.
- Tealight candles: These are the most common heat source. You’ll need a few to get some warmth.
- Metal stand or base: Use something sturdy like a cake pan or a metal stand to hold the candles safely.
- Metal rod, nuts, bolts and washers: These will hold the clay pots together and create space for air circulation.
- Tools: A wrench, screwdriver or pliers will come in handy.
If you’re buying materials, you can find most of them at a local hardware store or online. Or you might already have some of these at home.
For comparison, a reptile heater works on similar principle of emitting heat but is designed for a controlled environment like reptile tanks.
A clay pot heater is a more versatile and cost effective DIY option for general heating.
How to Make a Clay Pot Heater

Making a clay pot heater is easy even if you’re not a DIY expert. Here’s how:
Step 1: Gather Materials
Lay everything out on a flat surface so you can see what you’re working with. Check the list to make sure you didn’t miss anything.
Step 2: Prepare the Base
- Set up your metal stand or base. This is where the candles will sit, so make sure they are sturdy and heat resistant.
- If you don’t have a stand, you can use an old cake tin or even a few bricks to stack securely.
Step 3: Assemble the Clay Pots
- Take the small clay pot and thread the metal rod through the hole at the bottom. Use a nut and washer to secure it in place.
- Next, stack the larger pot on top of the smaller one, leaving an air gap between them. Use another nut and washer to secure it. This allows the heat to transfer evenly between the pots.
Step 4: Place the Candles
- Put your candles under the clay pots. Tealight candles are the safest and easiest to use. For more heat you can use larger candles but make sure they’re secure.
Step 5: Light the Candles
- Light the candles and slide them under the pots.
- Wait a few minutes for the clay to absorb the heat. You’ll feel the pots getting warm and soon they’ll start radiating heat.
Step 6: Test and Adjust
- Like most other machines, the efficiency of your clay pot heater depends on the setup. If it’s not warm enough you can try adjusting the height of the stand or using more candles.
More Tips
To get the best out of your clay pot heater:
- Ventilation is important. Make sure the pots are high enough to allow air to flow under them.
- Choose the right candles. Unscented tealights are best as they burn consistently and don’t produce soot.
- Be careful. Never leave your clay pot heater unattended and keep it out of reach of children and pets.
Advantages and Disadvantages
Advantages:
- Cheap: You can make one for under $20.
- Portable: Easy to move from room to room.
- Eco friendly: No electricity required.
- Great backup: Perfect for emergencies or power outages.
Disadvantages:
- Limited heat: Good for small spaces but won’t heat a whole room.
- Not for long term use: It’s a temporary solution not a full heating system.
- Safety concerns: Since it uses candles it requires supervision.
Compared to an electric heater or a reptile heater it’s a lot simpler and cheaper but won’t replace the convenience or power of those.
Other uses for a Clay Pot Heater

- Camping: A clay pot heater is a great way to stay warm outdoors.
- Greenhouse heating: Use it to keep your plants warm in colder months.
- Decoration: Even when not in use it can be a rustic centerpiece.

- Place it on a flat surface.
- Keep flammable items away.
- Never leave it unattended.
