You may or may not be aware of all the DIY heater ideas out there, but there are a few circulating that are worth knowing how to execute in an emergency or just for some extra warmth in a drafty room!
You never know when you may be without heat in an unexpected weather scenario or want to warm up a small space when camping, living off-grid, or maybe your local power supply isn’t reliable.
One simple heater people are making and sharing around the internet is the terracotta pot heater, an illustrative name for a simple yet effective device.
If you’re lazy or want something decorative and don’t want to put in the effort, they are available premade on Etsy for a hefty mark up compared to the cost of materials.
Terracotta pot heaters are tremendously easy to make yourself though they might not look as pretty. You may already have many of the items needed laying around your home.
In this article – we’ll showcase some of the best and most beautiful terracotta pot tutorials we find.
We’ll also show you how to build your own!
Building a Terracotta Pot Heater From Scratch!
Building a terracotta pot heater is easier than you think – even if you’re not sure how to start.
Before you start building, you will need to gather some supplies. It is critical to mention that not all terracotta pot heaters are created equal in utility. Some don’t work!
(While some of the nonfunctional variety don’t work that well. Others offer splendor to any home decor. But, let’s talk about the heaters that work.)
Some methods on Youtube show the builder only using one terracotta pot which doesn’t get as hot as using multiple-sized pots that fit into each other, like a Russian doll.
The heater works by concentrating all the heat from a tiny candle flame into a single point and then helping it to radiate outward. Using two or three terracotta pots stacked on top of each other will radiate more heat.
- 2-3 terracotta pots of varying sizes; one small, one medium, one large.
- One bolt, 1/4 inch to 1/2 inch thick, 4-5 inch long, and a nut that will fit the bolt.
- Washers 10.
- A candle or two, depending on the candle size. Shorter and stouter are better.
- 3-5 Bricks or some other non-flammable object to prop up and support the pots (In one video, a gentleman uses a hefty saw blade.)
The Assembly Instructions
Place the smaller pot inside the larger one. And then again, if you have three.
Push each of the bottoms together and thread the bolt through. That way, the nut is on the inside of the structure.
Use as many washers as possible to provide more metal for heating.
The number of washers you can fit will vary depending on the thickness of your pots and the length of your bolt. Tighten the nut and bolt by hand until the structure is stable and sturdy.
Now it is time to arrange your bricks or metal or whatever flame-proof items you have chosen for a base. Note that it is vital to leave space for air to travel under the pot’s foundation for a few reasons.
One is so the fire can have enough oxygen to continue burning and so that air may flow in to get trapped and warmed.
One experienced Youtuber claims that you must have an open hole towards the top of your clay pot heater (aside from the bolt hole at the base of the pot).
The open hole, he explains, helps warm air can flow freely.
(It makes sense to us!)
The air flows after being sucked up through the space we created earlier at the bottom of the heater above your bricks.
That said, it is worth finding a pot with more than one hole in the bottom. It isn’t 100% necessary, but something to consider worth experimenting with and considering.
There are a ton of tutorials online for free walking step by step through the process of drilling through terracotta.
Remember to wet the terracotta before any drilling to avoid cracks!
