Every candle you add will raise the temp of output 2 degree which will increase the radiant temp 2 times by adding one more candle under each pot you would raise the temp in your room about 5 degrees. And put a few pennies under the rim of the pot to increase the airflow and it will make the pots hotter to increase the radiate heat more. I do this and in a hour you will not touch those pots with your bare hands .

A couple of things. Don't need candles. Any rope/string or even rolled cardboard will work. Second, u can skip the microwave n fridge steps. Just put a wick in the oil. Make sure it has oil rubbed on it. Then light also, u can use a paperclip to make the wi k stand up if u want. The more or larger the wicks, the faster the oil will burn but hotter. Also, don't need glass (which can crack). Just use old metal cans.

Very nice. I actually run survival classes, like what to do, what to hunt for in an emergency. And yes, this works. If you place some coins underneath the pots to raise them up about a quarter inch, you can heavily increase the heat output. Because with your setup, the candles are starving fir more oxygen. Try that and post an update video, you'll be amazed. Also, if you're late in the game, wax, hair grease, etc. All these different things work. I made my own cook top with some close hangers and an empty coffee can. I had boiling water etc. From a similar setup. Love the video, keep them coming! Necessity is the mother of invention.

Ma'am as a young 19yr old individual who is currently homeless and struggling to find ways to heat my RV during the cold nights, I wanna say thank you n would love to try this with my 51yr old mother.

One word of advice when the house loses heat due to a power blackout… make sure you turn off the main water to prevent a flood when the pipes are frozen. Always turn off the main water when you leave the house for a vacation whether winter or summer. Turn the water main off!

I did this last winter in Texas when we had aweek of sub-freezing temp and no power. My neighbors' homes were @25 degrees, but our home was 48 degrees.

I've been living in an RV for years. (I'm a retired General Contractor). I not only made one similar to this better upgraded version in this video, but I also burn candles on my shrine. My method for adding oxygen is to open a window with a gap the size of a toothpick. This allows oxygen to enter 24/7 regardless if the candles are on or off. Thanks for the idea of the directional flue heatalator and the vegetable oil, and yes, a gap under the pot allows for air flow to supply the oxygen.

You can use small mason jars. They can take the heat. Thanks for that great survival tip. We really need them now😊

I'm always looking for non technological ways to deal with emergencies. The video itself gave good basic information but the comments below gave me a lot of technical tweaks to make it a more efficient setup so thanks to EVERYONE for the input...

Warning make sure you use glass that is designed for getting hot for your candle otherwise they can shatter if they get too hot and the lard can start a grease fire like you won’t believe. Make sure you have a grease fire extinguisher. Because this is a liquid fuel source it can leave a oily residue if burned for many times. Put three pennies under the candle glass to get air circulation so the glass stays cooler and helps use that heat. Next put three pennies under the pot so that air can move up through the chimney and keep the flame clean instead of starving for air which makes it smokey. Make sure all of this sets on a ceramic base. Simple little things like this can increase efficiency by quite a bit the key is do not let that flame starve for oxygen it will get smoky and will not generate clean heat. Also if you move the candle a little off-center then the heat has time to warm the pot instead of going straight up the chimney hole. Wicks tend to fall over as it heats up so keeping the candle as cool as possible by doing the above will help her greatly. If you use a wick that has metal in it it can become smoky as it burns down and give off metal particles. Try to find wicks that are smokeless but are more rigid to stand up straight. Are used a small piece of metal with a hole punch through it and push the wick up through and put that at the bottom of the glass to keep it from tipping over. This is fantastic for survival and emergencies but wouldn’t use this on a regular basis.

Just be careful with this because shortening is probably just like candle wax where the liquid wax/ shortening can get so hot that it hits a flashpoint and kind of explodes in flame. This happens when everything left in the jar has been liquified by the heat...in other words, none of the wax is hard anymore-- it is all melted. This happened to me once with a candle and the jar broke and the flames shot up about a foot. My carpet and dresser top started on fire. If the noise had not alerted me it would have caught my bedroom on fire.

Great idea it would work a lil better if u put some pennies in a few spaces under the pot to create space for air flow it will increase the heat output.

Good video. I sit mine inside a cast iron skillet, instead of terra cotta trays. It warms the cast iron, giving off even more/longer heat. Put 4 pennies underneath rim of pots. I'd remove the paper tag on everything, so those don't catch fire. Cheap coconut oil, from $Tree, easily removes all stickers.

In this Darn age, we need all the hacks that will keep our home warm, pretty clever idea 💡 thanks for sharing this with us all.

Burquenas!! Hearing, "I'm in the 505", warmed my heart!! 😊

Well I just turned 59 years old last week, and I guess I'm never too old to learn something new this is really interesting, I'm glad I found this looking at UKposts today thank you for sharing this information with us.

During the Texas ice storm I used a small Crisco candle to help keep my Motorhome warm. I used a short Shabbat candle for the wick. In my propane oven I warmed large flat rocks wrapped in towels to sleep with. I had no heater, no generator, and couldn’t use propane at night. I burned several candles safely. The crisco candle lasted for days. This looks interesting. I will try it with a larger pot with one crisco candle. Since surviving in South Texas with no electricity I now have a hot water bottle and a crisco candle on hand for emergencies..

Yes I've tried this many years ago but used cheap tea candles from dollar tree, the lard is definitely going to burn much longer and I didn't think about capturing more heat with two elbows instead of one, another tip I s that I found that I could increase the heat by placing several flat metal washers on the top of each pot as they got so much hotter than the pots alone and some have suggested putting coins or washers at the bottom of the pots to increase airflow like a wood stove, it creates just enough airspace for a better burn

This could be helpful, though living up up north, I might prefer a small little wood stove. Since you are so helpful, I should tell you about grape seed oil I see in the back ground. I used to consume grape seed oil, but then I heard it is processed in an unhealthy way, and since then I have learned to only consume quality olive oil, and coconut oil, being the two healthiest oils. I use coconut oil for cooking because it can handle heat the best, and I prefer olive oil for cold applications, and for it's flavor.

*Tuna Fish cans instead of glass jars... *Cut a piece of window screen (metal, not plastic) in a circle to fit inside the tuna fish can .. *Punch a hole in the screen same size as the birthday candle. *Melt shortening and pour into can .. let it cool just enough that the screen wire stays on top of the shortening instead of sinking to bottom of can and insert candle into hole in screen. *Cut another piece of window screen wide enough and long enough to be folded twice so that you have a triple layer of screen and place it under the tuna can. Provides air circulation and keeps can from heating the terracotta dish to a dangerous temp. *Place four nickles (pennies are too thin) under the lip of the terracotta pot to supply oxygen to the candle. Add enough water into the dish to just barely touch the bottom of the can .. does two things helps keep the dish cooler and puts moisture into the ambient air of the room. With only one candle in just one pot.. there is no worry about carbon dioxide in a typical size room .. say.. 8 x 10.. These little heaters work great in a "Wall Tent" to keep the chill off.. don't recommend using in a "Pup Tent"..

Melt Crisco in pan Pour into jars (let cool some) Run a wick through a hole in a straw poked with an ice pick Straddle straws over the jars until they cool completely. 💛

As people try to reduce their energy costs this year, ideas like this are important to share. Thanks for the video. I am not sure why there was a need to microwave, or why you didn’t put a bunch in large glass measuring cup, microwave, and then pour into the jars. I would recommend instead of cutting the candles like you did, score about 1/4” below the cut & pull off the wax, leaving some wick out.

I think you can actually heat the Crisco and pour it into the jars. It will solidify once it cools. It seems much easier than forcing it in with a spoon. Then you may be able to just force the candle into the Crisco. It's worth a shot.

UNBELIEVABLE! I had this video in my watch later queue, forgot about it and went 2 weeks without heat when our furnace broke. Now I find it! ugh...I subscribed. Thank you

Bless you lady xx all them foal billionaire's should see this and hold heads in shame that someone's mum has to think outside the box. Bless you ❤️❤️

Awesome setup! I'm going to give this a try as I'm trying to make my camper non-dependent on electricity. I'm also in the 505 and you're right, it's definitely cold out there!

My advice is to chose something other than glass jars to use as a candle. I would use tempered glass that is oven safe, or cut soup cans. Use a small piece of tin foil to create a ‘foot’ at the base of candle or wick before inserting, this way it doesn’t fall down when oil liquifies. We live in the Northeast and often lose power during storms and it gets below zero in winter. We invested in a woodstove, harvest fallen trees year round, it’s on-going to chop/split wood because it takes a year to season wood, what we cut this year will get used next year. They do make mini woodstoves for tiny homes that are cheaper than a full sized one, and yes, a vegetable candle will work inside them and they can heat an entire room. This way, there is far less chance of carbon monoxide or grease build up.

No ducks were harmed during the making of this video..

Very true It works!! Used this method during the time I was homeless.. Saved my cold days n nights (fall/winter) ... Shared this idea with other homeless I help now. 👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼

I watched a few similar videos yesterday and commented that they were a good idea. But you made the heaters even better with that stove pipe. Thanks for the idea. I will make these.

I think it's a SMART idea for a small room and at that little expense you can add more. The idea as shown is not to get your room or rooms to 70 but at a temp you can survive on a low budget!😊👍

Kuddos to you ma'am! What a great and economical way to survive and thrive too! BTW...you have beautiful hands! I enjoyed learning something new but simple! Thank you & Merry Christmas!

This is a good thing to have on hand when prepping. Simple and easiest are usually the most efficient. Thanks for this video

I like this idea, I saw a demo where a can of Crisco or your choice of oil and candelabra candles were used for light, and was stated that it could be used for up to 12 hours these are great ideas for when the power does go out for long periods of time.

These are also excellent for camping trips. And for those who live in cold areas I would suggest carrying one in your vehicle for emergency heat, if you should break down and have to wait for help. And if you carry a couple cans of soup or chili with you you can use it to heat those up as well. 🤠🐂🏞️🛩️

Who's a hero.you r. Mine. I've been working on candle heat for a while now,but the candles were getting expensive so thank you.

Try placing three washers equally spaced under your pots to give more oxygen to increase the efficiency of your candles.

Great tip to get you prepared before an outage; might save your life. Thanks for sharing.

I like all your little comments during filming, that was about everything I was wondering. I'll definitely be buying these inexpensive items for an emergency heater option. I was hoping you'd show how the candles were blown out and cooled down, and how long that took, and maybe what you paid for everything, but I think I get the jist. Thanks for sharing!

I apologize, my previous comment didn’t include a huge thank you, I appreciate you posting this very helpful video. I loved the added elbows to the pots. I’m gonna go and purchase what you provided in your video. Abundant blessings to you.

THAT'S ABOUT ALL THAT HYDROGENATED VEGETABLE OIL IS GOOD FOR!!

I wouldn’t use the galvanized duct elbows. As the galvanized coating burns it gives off toxic fumes. Use the black ones instead

Oh wow! I wish I knew this method when my furnace died for a few winters. I have a new one thanks to the county. These aren't exactly cheap (also not expensive), but having no heat is deadly and makes you ill. I have dogs, so my fear would be them knocking it over. The same goes for kids or burning themselves on the candle or hot aluminum. Still a game changer for many people. Thank you for showing everyone.

Thank you Nica. Love this DIY heat system Adding it to my survival kit. YAY!!

This lady literally found a way to burn fat!!!! Awesome.

I recommend placing these in a metal garden tub at least 24" diameter made of galvanized metal filled with a bag of sand, not cat litter, You can do this instead of the ceramic mat. Place the galvanized tub with sand on the floor level, Thank you for sharing this idea. never allow water or rain to touch glass or ceramic while burning.

Going to try this in my greenhouse this winter. Thanks for the content and the comments.

THANK YOU FOR THIS GREAT IDEA.. ABSOLUTELY FABULOUS.. ENJOY, LOVE & LOTS OF WARMTH W/ LOTS OF LIGHT MY FRIEND..

If you pipe the shortening in with a frosting bag it fills the jar without empty spots. Just put the tip to the bottom of the jar and as it fills slowly raise the tip untill fill.

Loved the dryer vent elbow usage and it radiates the heat easily! Nice job!

Awesome, thanks for the info! I have bought several containers of the vegetable shortening to make my own candles for warming, got a bundle of wicks from Amazon. Back to the hardware store for ducts .. have a blessed day ❣️

Thank you for your video. I plan to pick up these items so I will be ready for any emergency

Many years ago, a friend of mine made something similar to this to heat his ice fishing shack. If I remember correctly, he used (2) 4 inch elbows, (2) 4 to 6 inch stove pipe adapters (in place of the terra cotta pots) and a rectangular steel plate instead of the 2 terra cotta plates. He also made some lard candles (like the ones you made) to heat it. He actually attached the 2 elbows and then drilled a few small holes at the top of where they were attached. He also drilled a few small holes on the lower side of the 4 to 6 inch adapters. The holes he drilled allowed the heater to "breathe". The whole contraption was set on the rectangular steel plate. It actually did a good job of heating the shack, and was a lot easier to deal with than a wood stove.

You need to put a small spacer under each pot, such as 3 nuts or thick washers, so the candles can get enough air, and the hot air can get out! Then try that thing with 3 candles (tea candles) in each pot, and you'll feel a difference. Have gloves or potholders ready.

Thank you SOOOOOO MUCH!!! God Bless you for taking the time to post this video🙏❤️✌️😎

Wow. Such an awesome idea ❤ thank you so much. I will be making one of these very soon .

I really enjoyed watching this video and agree with most of the positive comments. What I didn't read was about ventilating to get rid of carbon monoxide. Any burning type of heat removes oxygen so be careful.

Thank you for sharing. I am planning to use this in my covered 3'X12' citrus/tropical raised bed this winter. I tried this when we lost power in Texas early this year. It works in small spaces.

Excellent!!! I saw something similar on a Homesteader channel, a year ago, but not with the terra pots, which I like better. Thanks so much.

Awesome idea!! My friends are moving from Florida to Tennessee. I am definitely passing this on!!😮😊

I really love your experimenting. The inexpensive items make it fabulous. Simplicity makes it great. These ideas make it fun.

I used a stainless steel trash can . It did great

This will date me but when I was a teenager, my mom was our Girl Scout troop leader. She taught us to cook on a metal coffee can and make a cardboard oven and cook biscuits on a stick. At the time I was sooo embarrassed, you know, too cool to be seen in my uniform. But now, I look back, especially now that she is gone, and I can appreciate all she tried to teach us.

Wow! Thank you! Now I have peace of mind for this coming winter. I'm sharing this with my whole family. :)

Smart idea the low position of you candles give the pots and ducts a chance to heat up, I would have liked to see a small room heated with these and temperature readings to get a good idea how well these work.

Fyi, Test your wicks first, to avoid heat overloaded explosions! It's not talked about much, but is extremely helpful. Low melting point fuels, like shortening, combined with a high heat throwing wick, will radiate the heat quickly to the jar. If your jar is too small, the heat can overstates your jar, causing it to explode, and fireball. To avoid this, you can test your wicks! Just pour your fuel into a large backing pan, place your wick in the middle of the pan, then light it for 2 hours. Once the fuel burns, you will have a melting pool ring, around your wick. That melting pool ring, tells you exactly what size jar you need to use for your specific fuel, and wick you have selected. Anything smaller than your melting pool, will be at risk for heat stress fractures and explosions. Anything at size is perfect, and anything larger than that will also be ok, but wont sustain the heat as well through the whole jar. Testing wicks is a huge deal, especially for use in heaters. Hope this helps you create a little saver candles that won't fireball on ya. It's happened to me, so I figured I would pass on the helpful tip!

Great job! I love the ceramic mats! Good idea!

Amy Suggs and Just Me from Iowa covered what I would have suggested. My concern would be the glass jars and the flammable nature of vegetable shortening. Therefore I'd go with a tin can full of the shortening, or even use something like a lighter fluid can, fitted with a meths burner wick. Four or five such cans placed in a radial pattern inside a large flower pot, would allow for good air flow around the cans (keeping them cooler) but would give four or five heat sources. Terracotta standoffs or broken pieces of flat ceramic tile would support the flowerpot in the base for adequate air flow. Also, on further reflection, I'd say using two 'T' flue junctions positioned together (if using two stoves) to form a 'H' configuration would probably be more efficient in radiating the heat and aiding convection. One 'T' section could be used for one stove.

Dont forget, you can stack multiple pots for greater heat storage

Thank you! for sharing one of the coolest DIY’s I’ve seen. Can’t wait to experiment. ❄️🔥

A good idea for temporary green house or caterpillar tunnel heat to extend your garden growing season. I am gonna try this in my tunnels this winter.

Hello Nica, Thanks for this demonstration. I'll try it out; just got to gather materials.

The 5 -0-5 REPRESENTING!!! WAY TO GO BABE!!!! fellow New Mexican here too & this is SUCH A GREAT EMERGENCY HEATING HACK! 🙇🏻‍♀️ thank you SOOO MUCH for sharing w us!!! 🙏🏼You're incredible!🤗 KEEP DOING YOU BOO!!😘

Thank you for sharing. I see a lot of people have added great tips to make even more efficient. Something I learned recently and will be making for lights if power is out is DIY oil lamps (I'm asthmatic and I probably can't do the kerosene lamps anymore). You can find a bunch of tutorials on YT. My suggestion is using cotton kitchen string (cheaper than candles!) instead of candles, and here is why: you want the *oil* to burn, not the wick. The wick absorbs the oil to allow for lighting and burning, which should burn hotter than just a candle. Yes, the wick will need a support to be held out of the oil, but plenty of videos on how to do that. I hope my addition helps others and this video is definitely helpful to me, especially with the comments of tips. Thank you all!

Great video and lots of good comments. This video really got the conversation going. Thanks for sharing your ideas and tips!

This was a very useful video. Thank you so much for sharing!!!

Out of all the methods I have watched, I like yours the best. Thanks for the video

From México AND from my heart....thank you!!...it's a great idea!!!

So simple yet very neat. Great for emergencies!

What A Truly ingenious idea!! 😂👍😊 A MILLION THANKS!! 😎🙌🙌🙌

All I know is that we lost electricity and lit about 15 candles, and it stayed nice and warm in the house, even though it was very cold outside. Candles can help.

There is nothing wrong knowing how to look after ones self in an emergency. This type of device is for emergency purposes. Which can be modified to be more on the safe side. The bigger the wick, the bigger the pot. Do not leave this or any candle unattended. Soot is a result of too long a wick, lack of air or both. Incomplete combustion. Have a working smoke detector (they never sleep), but they don't replace fire safe practices. Be safe and stay warm.

Thank you kindly ma'am. You are appreciated 🙏🏽

This is amazing, thank you for the knowledge!

Nice & a Much Simpler way to do this would be to just use candles already in glass jars especially in emergencies where you won't have any power or microwave. Even just a large tin can with holes in top will produce heat over any candle.🔥

Saturate pots by adding water in tray to keep humidity or moisture in air

Thanks for the info…. We’re getting closer and closer to our time of need

I’m doing this TODAY! Thanks for sharing…God bless!

Finally someone found a good use for this garbage shortening! I love it 🙂

Wow, most creative, practical option I've found yet. Bravo. Thank you so very much ❤️

It would add more heat if you put a "t" of your pipe, joining the two together. Any metal pipe heats and retains the heat. Thank you for that idea. I have knowledge of the terracotta heater but you have upgraded it. Very ingenious!

Live this bud! Shortening the answer to expensive candles!!♥️

Dear! Thank you very much for your time and effort making a wonderful contribution to mankind at large with this outstanding video! Thank you very much! May the Good Lord Bless you! Thanks again! XOXOXO

I bought everything yesterday. I'm doing it. I live in Canada and want to keep my heating bill low

Thank you for this. Great idea!!

THANK you, Nica! I have been a preparedness nut for about 49 years, and I have NEVER learned of a way to heat ANYWHERE! I am going to send a link to all my children and friends. You are awesome.

Very efficient emergency measure. May be required come this winter. Thanks

we truly suffered here in texas durring that haarp event....I pray for us all.

Wow. I live off grid so I love this kind if stuff thank you

This will be great for when my son goes on his church retreat. They go to Oklahoma and it's still cold at night where they go and he said his feet never got warm the whole week. The comments really helped, also . I'm going to keep the supplies on hand this winter since Texas has that grid issue. 😆
