I really liked the idea! Both the materials are available and inexpensive... In general, in search of an inexpensive heating source for your not yet built autonomous dacha, I came across the article “A fireplace made of pots heats a room with one candle.” According to the developer, this device can successfully heat a room and actually heat water on it. I quote the article in full:
The candle flame shines quite pleasantly, but trying to warm up with it seems crazy. Meanwhile, just as a light source, a candle is an extremely wasteful device. But as a room heater it can be useful. Under a number of conditions.
Californian inventor Doyle Doss and his company DOSS Products offer original system Kandle Heeter, that is - " Candle heater».
This strange-looking candlestick, its creator claims, can be indispensable during a power outage. Its height is about 23 and its width is about 18 centimeters.
And from it appearance The inverted pot above the candle attracts attention. In this pot (and he is in a “past life” flower pot and was) and the main highlight of the system is hidden.
This pot is not simple, but composite. It is made from three pots different diameters, nested one inside the other and connected by a long metal bolt, on which a whole bunch of washers and nuts are strung (fortunately, the pots usually already have holes in the bottom). 
This intricate combination of ceramic and steel is called Quad-Core, and is designed to trap heat from a candle. But why?
An ordinary candle, burning in a room, produces, as it seems, very little heat. But the point here is that its hot “exhaust” simply goes up and quickly evaporates with the ventilation.
Meanwhile, the energy reserve in the candle is not so small. Moreover, with the hot flow of combustion products, most of its energy content leaves, and only a smaller part is converted into light.
The labyrinth cap above the flame collects energy and carefully stores it, heating up quite strongly (the central rod is especially hot). And then this heat is slowly transferred to the air by the entire surface of the ceramic radiator.
The pots also help trap soot from the fire, which helps keep the ceiling clean. 
The inventor emphasizes that one such device will in no way save you in the winter when the heating and electricity are turned off, but, on the other hand, it is better than nothing at all.
In addition, although this simple design is designed primarily for emergency situations(and not only at home, but also outside), a mini-candle radiator can slightly reduce the cost of heating a room, adding a little warmth to an occupied room, while the entire house is “adjusted” by thermostats for more low temperature. Here, however, you still need to calculate the cost of one joule per candle.
The heater is also equipped with a top-mounted stand that can hold a pot of soup.
Before a fresh Kandle Heeter can properly heat a room, you need to wait for the residual moisture to evaporate from the ceramic. This can take 3-4 hours, Mr. Doss notes.
But then the owner of this thing can fully enjoy soft warmth, produced by the heater for a long time. It is necessary to store the unused device in a plastic bag so that it does not absorb moisture from the air. 
Heater operation diagram. The flame heats the rod (1), hot gases pass from cavity to cavity (2), each layer of ceramic emits infrared rays, heating next layer(3), the outer pot (4) ultimately heats the air in the room (5) (illustration and photo from heatstick.com).
Doss writes that a 4.25-ounce wax candle contains approximately 1 thousand BTUs of energy. In conventional terms, this is approximately 120 grams and 1.1 megajoules.
If we consider that such a candle burns for 20 hours or a little more, it turns out that its energy production is 55 kilojoules per hour, which corresponds to a power of 15.3 watts. 
True, according to some data, the total “useful output” wax candle this size will still be higher. Closer to 3 megajoules. Which will give an average power of approximately 42 watts. And if we carefully “look” at a paraffin candle, then, perhaps, we will find even more potential heat in it.
However, the exact calorific value numbers are not so important. It is clear that such a candlestick cannot compete in power with household electric convectors and oil radiators at 0.5-2 kilowatts. As long as there is current in the outlet.
On the other hand, even if there is current, you are unlikely to burn a kilowatt heater all day long if you do not want to go broke on electricity bills. And Kandle Heeter, as already mentioned, lasts more than 20 hours on one candle. The only thing important condition: It must not be left unattended. Still an open flame.
The American innovator believes that such heaters should appeal not only to people sitting at home, but also to those who rarely go there, preferring to travel away from the hustle and bustle of civilization. Kandle Heeter should become a simple and cheap alternative to primus stoves and other kerosene stoves. And someday it can save the life of a person who is caught, say, in a car in a snow trap or a blizzard.
Lastly, this tiny firefly is just cute. “Kandle Heeter should remind us all that once upon a time we (humans) sat in caves at night around a fire and told each other stories,” says the inventor.
This is the article!
In my opinion, this is not a bad idea, especially if instead of a regular candle you take the one described here, with an asbestos wick and wire. The only thing that confuses me is oxygen... Will this device consume a lot of oxygen in such a small room? Who thinks what?
Candle flames have long been used to illuminate homes, but they have never been used for heating. The situation was changed by California inventor Doyle Doss, who developed the original Kandle Heeter candle heater. It's worth paying attention to because:
- The materials for manufacturing are the most common and inexpensive.
- The device will be useful when the heating is turned off and outside the house.
- The original appearance can be made part of an original rural (country) interior.
- The Kandle Heeter design collects soot and soot, leaving walls and furniture clean.
- The simple design makes it easy to make yourself.
The height of the candle heater is 23 cm, and the diameter is 15 cm pot + several cm supports. One candle burns for about 20 hours.
The principle of operation of a “candle heater”
At first glance, it seems that a flower pot was turned over and secured above the candle.
In fact, the device consists of several ceramic pots, inserted into one another, like nesting dolls, and mounted on a metal rod.
Large number of nuts and washers various diameters, also strung on a rod, is also an important part of the system.
Such a “fungus” above the candle is needed to capture, accumulate and release heat from the candle flame to the room. The fact is that usually all the energy of the fire rises and does not significantly affect the temperature in the house. When using Kandle Heeter, the flame heats the central rod and rows of nuts. Gradually, the heat is transferred to the ceramics and then to the air in the room.
Ceramics, or baked clay, was not chosen as a material by chance, since it perfectly accumulates heat and distributes it throughout the entire volume.
Do not leave the micro-oven unattended - after all, it is a small but open flame!
Energy
It is not surprising that there is not so little energy in a candle, while most of it evaporates and only a smaller part is used for lighting.
How much heat can you expect:
- Wax candle weighing 120 g. produces approximately 1.1 - 3 mJ.
- In an hour this is 55 - 150 kJ.
- Those. mini radiator power: from 15.3 to 42.5 W.
A paraffin candle gives better results.
Candle heater as an interior detail
Of course, one such device will not replace powerful heaters and cannot be counted on as an alternative to heating. Rather, it is an opportunity to warm up in extreme conditions, or a decorative thing that will make life a little (2-3 degrees) warmer.
In addition, it is not often that we turn on powerful electric heaters for 20 hours straight - this is an expensive pleasure. Burning one candle per day is much easier.
You should not use a simple candle without a glass glass. It will melt too quickly.
DIY candle heater
Materials
To make a cap you will need:
- Three ceramic flower pots of such diameters that they fit easily into each other (smaller pots should not protrude from the largest one). For example, 5, 10 and 15 cm. Preference is for pots with a hole in the bottom.
- Metal rod with thread, diameter 6-12 mm.
- Nuts – approx. 8 pcs.
- Washers – 20 pcs.
- Ceramic candle stand.
Step by step instructions
The holes in the pots (if necessary) are drilled out to the diameter of the rod.
- A rod is inserted into the largest pot and secured from the outside with a nut.
- Inside the pot, several washers are strung on a rod.
- The second largest pot is put on and secured with washers and nuts.
- The third pot is put on and also fixed with metal elements.
- The cap is attached above the candle. The flame must be strictly under the metal core.
All work must be carried out very carefully, since ceramics are very fragile and can crack if the nuts are overtightened.
You can use a non-flammable sealant in places where clay contacts metal - this will reduce the risk of cracks and chips.
Support
In principle, any non-flammable object of suitable size can serve as a support. For example, three bricks. However, if you try, you can arrange everything in a more civilized manner. You will need:
- Three flat metal corner which ones are used to strengthen window frames(One edge of each corner should be equal to the radius of the candlestick, the other = the height of the candle jar in the candlestick + 2-3 cm.)
- A strong harness, wire or cord.
- Welding machine.
- Drill.
The simplest brick support
Instructions for making a support:
- First, you need to weld the metal corners at 120° to each other. The smaller ends face inward and are welded in the center, the longer ends face up.
- Small diameter holes are made in the upper part of the long ends. It is important that they are at an equal distance from the top.
- Wire is threaded through the holes to form a triangle. A cap is placed on this cord support.

And here you will find out why convector heaters are the most popular and whether it is worth purchasing such a device. Review of models and reviews from owners.
Use and storage
After the clay radiator is completed, you can “turn it on” for the first time, but be prepared for the fact that for the first 3-4 hours, the heat will not flow sufficiently.
This happens because the last moisture has yet to evaporate from the pots.
It is better to store a candle heater in plastic film so that the ceramics do not become saturated with moisture.
Conclusion. In America, such mini heaters are successfully sold for $25 per unit. But in general, mini-radiators are just entering the lives of modern people.
Maybe residents of big cities will love it, because fire is a thing that can be admired endlessly. Perhaps hunters and fishermen will take Kandle Heeter with them to warm their hands a little. And perhaps someday such a baby will save a person caught in a snowstorm by car from frostbite.
Unlike conventional heating radiators, which heat the air, an IR heater heats the surface of objects. Many people choose because it does not take up space and heats the room well. Before you decide to purchase, find out about the advantages and disadvantages of the device on our website.

About the heater from flower pots Many people have probably heard it. On the Internet you can find many articles on assembling and using such a device. These articles promise that such a simple device can replace electric heaters, since it heats up to 200 O C. Its assembly is simple and does not take much time. Such a heater is not suitable for a large space, but for small rooms, for example, a tent, greenhouse or greenhouse, it can be used. The heater will help out when fishing or on a hike, where it is not possible to use electrical appliances.
Since an open candle flame is used for heating, safety precautions must be observed. Do not place the device near flammable objects to prevent a fire.
Heater assembly
For assembly we will need:
- three clay pots of different diameters;
- 8 washers for M10 thread;
- M10 bolt 100 mm;
- 8 nuts with M10 thread;
- clay pan;
- metal stand (grid) to ensure air circulation;
- heating element - candles.
The device is assembled according to the matryoshka principle, that is, you need to select it so that they fit into each other, and there is a gap between them. IN drainage hole The pot needs to be inserted into the bolt after placing a washer on it.
Then you need to put a washer on the bolt with inside pot and secure it with a nut. Next, tighten another nut with a washer to ensure clearance, and fasten the second pot to the bolt in the same way as the first, so that the distance between its wall and the wall of the first pot is the same along the entire diameter.
We fix the third pot in the same way as the second. As programmers say: “We run the procedure in a cycle” until the pots run out. It turns out to be a matryoshka made from pots. Next, you need to make an improvised radiator for better heat concentration. To do this, fasten two nuts in series, put two washers on them and secure them with the last nut.
Principle of operation
The heater works quite simply. You need to turn the structure upside down and place it on the grill. Next we put metal stand on a ceramic tray with candles that will serve heating elements. Light them and wait until the heat is distributed over the surface of the heater. The structure will heat up most strongly in the area of the metal rod.
It is necessary to use ordinary ceramic pots without glaze or paint, as when heated it will burn and release harmful substances. In order to fire safety remove all labels from pots.
The house is warm.. The Baxi boiler works properly, maintaining the required temperature and providing hot water.
Outside the window - cyclone "Daniel", a snow storm... Messages on TV about the past "ice rain", ice on wires and de-energized populated areas They make you think: how can we quickly provide additional heating sources in case of a power outage?
The Internet didn’t disappoint.. I found something suitable.. I’m sharing..
Heater made from flower pots
To create it you will need: 4 ceramic flower pots with stands different sizes - 2 small and 2 large ones (the smaller ones should fit freely in the larger ones), 2 long enough bolts (they should be slightly larger than the height of the big pot), 2 chains, nuts and washers. You also need to make a special holder on which the mini-heaters will hang.
1. First, drill holes of the size you need in the pot and stand, then thread the chains through the bolts and secure them with nuts. Insert the bolt through the hole in the pot, put a washer on the bottom and secure it with a nut.
3. Alternately put on the washers and nuts until they stick out a little from the top of the pot.
4. It's time to make the bottom of the heater. Put on the stand and secure it from below with a washer and nut.
5. That's all. Now all that remains is to repeat all the above steps with another flower pot.
6. Hang the pots on the holder and place a few candles on the stand. The heater is ready!
In this video, the entire manufacturing process of the device is shown quite clearly.
This heater can be used not only at home in winter, but also in the evenings outdoors. It will save you a lot of money in winter time, so you should definitely use this advice.

DIY heater made from flower pots and one candle
Some inventor Doyley Doss I figured out how to heat a room using flower pots and one candle. To do this, he decided to make an unusual DIY heater.
He took 3 clay pots, placed them inside each other and screwed them together with a bolt of suitable diameter. During assembly, he tightened the structure with nuts and placed washers in the gaps. The bolt was matched to the entire depth of the largest pot (the first had a capacity of 1 liter, the second 0.6 liters and the third 0.2 liters).
Thus, the result is a kind of clay radiator capable of dissipating heat from a small household candle; clay pots heat up to 80° C, and a metal bolt up to 250° C. An ordinary bolt serves as a heat sink-distributor from a burning candle.
In the process, it was discovered that the dissipated temperature quickly melts the candle and its service life is significantly reduced, so it was decided to use the candle in a glass vessel. This was both safe and economical.
So what happened - glass tumbler or a jar, there is a candle in it, on top of the candles there are 3 clay flower pots, bottom up. The entire structure is supported on a tripod stand cut from steel.
Later, it was invented Alternative option, where instead of a candle an infrared incandescent light bulb was installed. The result with a light bulb was more effective, since the approximate power of a candle is 15-20 watts, and the light bulb gave an excellent effect even with a power of 50 watts. The only drawback, unlike the first option, is that it is “connected to electricity,” which is less universal.
Let’s add on our own that our team conducted a small experiment to “test the benefits”, we can draw conclusions like this clay heater(with an infrared incandescent lamp) works economically, does not smoke and does not emit odors.
After a couple of hours, warmth is already felt a meter away, and after 4-5 hours in a room with an area of 18 square meters quite comfortable temperature 21-22°C, the temperature outside was 0°C, there were no other heat sources.
Of the minuses, we noticed only one - the long heating of the surface of the clay flower pot. But is this a minus? After all, any economical heater needs time.
On the plus side, there are solid pluses - economical consumption of 50 watt/hour, safe, environmentally friendly, you can attach a tray-plate from the kit on top and humidify or scent the air.
