Heat Your Home For Pennies a Day With Candle and Clay Pot Heater

heat with candle and clay pot

YouTube videos suggest that this terra-cotta pot space heater could provide affordable heat to your home for pennies per day, yet it poses several dangers.

Fire can be an especially serious hazard; paraffin candles burn at high temperatures and, should something knock over the clay pot heater, liquid wax could begin to flow freely and cause a large fireball.


The first law of thermodynamics states that the total amount of heat generated from candles or any other source remains constant, however if you place a clay pot over its flame it will increase room heating costs by providing more heat, helping you stay warm and save money in heating costs while even cooking food! Some even use this device during emergency power outages – due to clay pots’ ability to absorb and distribute heat more evenly while their terracotta material retains heat much longer than metal cookware, meaning you will require fewer candles for heating requirements!

Sterno cans provide another form of clay pot heaters, producing more BTUs than just candles can do and heating an entire room more quickly than candlelight would alone. Unfortunately, though, their increased output may result in dangerous levels of carbon monoxide (CO), killing thousands every year and necessitating users to check safety guidelines prior to making use of such appliances or fireplaces.

Terracotta clay pot heaters may give the illusion that they prevent air from rising to the ceiling; however, this is only partially true; instead they merely increase heat in any given location by increasing its levels slightly – not stopping air from rising directly toward you or your friends at all!

One of the key components of a clay pot heater system is its steel bolt that connects terracotta pots together. When this bolt comes into contact with an open candle flame, it releases carbon monoxide. Although not immediately dangerous, long-term exposure may result in unconsciousness or death; for this reason it should never be left unattended and should only be used in well-ventilated rooms far removed from flammable objects.


While some claim this device can heat a room, it’s essential to understand the first law of thermodynamics before trying it yourself. According to this rule, candles cannot produce more heat than they consume; some even claim using multiple clay pots or different sizes of candles will increase their ability to do this; this claim is simply false as candle heat production remains consistent regardless of its form – be it standing alone or within a clay pot heater.

Clay pot heaters are designed to capture and distribute heat generated by candles. To construct such an apparatus, you will require a metal rod, washers and nuts along with a small clay pot that has an opening at its base. Slide a washer over it before sliding a nut over it – doing this until all ends of the rod have been covered will help minimize fire risk.

After attaching the metal rod to the clay pot, place two washers on either end and connect each washer with six nuts – this will prevent overheating of the rod while helping retain heat in its entirety. As soon as clay pot is attached to rod, it will start radiating heat which will ultimately make its way throughout room and heating other pots as well.

Although this device may appear straightforward, there are still important safety considerations that need to be addressed. Terracotta clay can burn at high temperatures while chemicals in paraffin wax may be harmful if in contact with skin or even too close together may pose a fire hazard risk in your home.

While using candles in emergency situations can be beneficial, they should not be seen as a replacement for other forms of heating devices. Terracotta pots were never meant to contain flames and will overheat quickly due to air being circulated by burning candles, potentially spreading dangerous gases like toluene and benzene into your home and contributing to respiratory irritation or lung cancer.


As winter sets in, many are looking for ways to reduce their heating bills while staying warm at home. A popular TikTok trend involves using terracotta plant pots and tea lights as a low-cost heating solution – even as little as 4p an hour! While this sounds great on paper, its practical application requires considering thermodynamic laws first and foremost.

Clay pot heaters act like “heat batteries,” holding in and disseminating heat throughout a room more efficiently than traditional space heaters.

The center bolt, washers, and nuts will transfer heat from a candle directly into the clay pots’ centers; where it will build up before radiating out to all other pots in turn. While this process takes time to complete, it could save on energy costs significantly over time.

If you don’t have a center bolt, bricks or other materials may suffice as support for an inverted pot. When setting up the structure it must be located safely away from drafts and other potentially flammable objects – and avoid disturbance from curious hands or visitors as its exposed flame and wax could result in severe burns if accidentally overturned.

Clay pot heating can save both electricity and gas costs. Clay pots capture the warmth from candle flames, then radiate it throughout a room. However, unlike conventional heaters, this method does not actually heat a room directly – instead absorbing it into walls and floors of your home and emitting some amount of warmth out into it’s surroundings. How much warmth it radiates depends on factors like insulation levels in each room as well as whether ventilation levels in your house are sufficient. While not intended as permanent solutions it may provide emergency warmth during an emergency situation.


Clay pots are widely utilized in Vietnamese cuisine for creating rice dishes and stew-like stews known as kho (also ddukbaegi, tagine or cazuela). Clay absorbs excess oils and heat from food, creating tender yet flavorful dishes while keeping natural moisture intact within each bite for maximum flavor retention and reduced fat intake. This method of cooking reduces total dietary consumption significantly.

TikTok users have taken to using terracotta plant pots and tea lights as space heaters, providing cheap means of saving electricity during winter. While this method of heating might save money, there may be potential downsides that need to be considered before adopting such methods of warming a room.

One of the main issues associated with candle heaters is their potential danger if used improperly. To stay safe when operating this type of appliance, it is advised that a sturdy stand or bricks should be used to support its structure and at least two feet should be kept between it and any flammable objects as a stray flame can easily cause material near to it to ignite, potentially leading to accidents or fires.

Another hazard associated with clay pot heaters is carbon monoxide poisoning. When steel bolts come into contact with open candle flames, they may release CO gas which is odorless, colorless and tasteless; making detection hard before too late. CO is lethal when inhaled; many people die each year from CO poisoning while thousands more require hospital treatment for treatment.

An effective potted plant arrangement should meet your specific needs, placing pots at an ideal height based on these. As the higher they are placed, the more heat will be produced; however if too high up on a table they could cause accidents. It is wise to avoid touching pots during use to avoid burning yourself from touching hot clay which reaches extremely high temperatures that could prove hazardous.
