When I was a kid we had farmland with a small storage building we used as a hunting cabin. We used a Crisco candle and steel heat transfer made of 8-inch square stock. My dad split it and put offset baffles in it. It was 8 ft tall and stood in the corner. The cabin was small and insulated and the heat stack would keep it at 85 degrees when it was below freezing outside. It doesn't take much; just a little imagination and applied science. Thanks for the video.

When I bought my first car in Canada I was advised to keep, among several other things, a candle in the trunk. If you got stuck in a snowstorm you could light the candle and it would provide you with enough warmth to prevent you suffering from hypothermia.

Cool that your son was there helping you. He will never forget the fun things you guys do

Because of people like you, I have hope that the US is going to survive what is coming. You have taught me many things. May GOD be with you and your family. Merry Christmas. Keep up the great work. Our Mighty Father will bless you dearly for helping his children. Hallelujah

Energy has become so expensive in The Netherlands with the Ukraine war that this is an emergency solution for now. Thanks for the tip!!

We recently lost power in northern Michigan after a strong wind/ice storm went through. We had sustained winds of 20-30mph with gusts up to 65mph. We were without power for 41+ hrs. We don’t have any propane heaters or a generator (more and more people are buying these in our area), but we have a LOT of candles and bricks. We took a few ceramic tiles, placed either a big pillar candle or decorative holder that holds 1-3 tea candles in it on top of each tile, and made an arch over each, with bricks. The inner temperature in the house dropped from 65* F to 51* while we slept, before the outage was noticed. Once we got 3 of the brick warmers built and lit, we got the temperature up to 57*. The outdoors temperatures were from 22*F-34*F WITHOUT factoring in the windchill, during this this time period. We wanted to use more bricks, but none were available, so we used some cast iron frying pans! This allowed us to heat food and water, also. We are in a split-level home built in 2000. We stayed in the top level (where the bedrooms and one of the bathrooms is) and we were pretty comfortable throughout the whole ordeal. Now have to order some propane heaters, purchase another (2)20# LP tanks to keep filled, and a few more jugs for water. We had 3 large water jugs filled and ready, (made from recycled cat litter jugs)to use for flushing toilets, and 4 cases of 16oz.fresh water bottles for drinking, after the fresh water tank was depleted. If you want to make/use terra cotta pots for heat, one great idea for a base I saw, was using an old fondue base! Time to hit the resale shops! We have a hard time finding terra cotta pots here in the winter, north of the 45th Parrallel.😁Prepare, people! God bless you! New subscriber.😁😊

My family came over and we all did a total of 20 mason jar candles. 5 per house and we have stacked our bricks 🧱 in storage for safe keeping. Thanks for the video.

stone and concrete are amazing at holding heat in. When you are out in the wild, it is always suggested - if you can to build your survival fire beside a rock face. The rock face with absorb and keep the heat as long as the fire is going and you will still have heat after the fire goes out. This was a beautiful example of basic science. Well done.

The creep 1% has planned a power outage for a long time, so this upload is very useful

You could couple this with covering the door and windows with the exception of the 1 inch opening in the window. The more you insulate, the more heat you will hold in, allowing temps to build. Thanks for the test. Great video! 😁🤙

Great idea. Try this... Add a vaporizer effect by setting a pot of water on top of each heater with a lid, just off slightly. Your room will be even warmer. If you've ever used a warm vaporizer, when your kids or you have the croup, you know how warm steam raises the warmth in a space like a bedroom very quickly. Give it a try and see if you get even better results.

Crisco is also good for waterproofing leather boots but it does have an odor . Just spread it on the boots and then put them in an oven on a low heat for awhile to let the crisco soak in. To get it out put them back in the oven till the crisco liquifies and wipe it off.

One of the better videos on this topic. I love the fact that he made use of the bricks to convert convective heat to radiant heat. If he had a 7 ft instead of a 12 ft cealing, the results would have been amazing.

Seems like you would want to find a small room in your house to set one of these up to keep warm, the smaller the room and the more insulation the easier it is to keep heated for emergencies. This guy kept a room at around 60 when it was really cold outside so it’s looks like they work! Can’t argue with success!

This guy is loved in the UK. Respect fm London.

Thank you for doing this. I really like videos which not only show you what they've build/materials needed, but ALSO show you the actual temperatures you might get and tell you the room size etc. It's not going to be the Bahamas where you all sit in shorts and t-shirts, but it would help keep you warmer in winter clothing layers, so every little helps. Not to mention the light the candles give out too. Some great emergency tips and ideas - thanks again!

Your engineering approach to an alternative to heating is admirable!! Thank you!!!

paraffin heaters were very popular during the depression and found in antique shops. often very decorative. they were very useful.

Best, easiest, most efficient method I've seen these past few days of research. Thank you so much.

Thanks for sharing your results. This would be a good addition for a winter prep. Even if you only had one you could set it up in a tent indoors

This was a great demonstration! Loved seeing the temperature, the CO2 monitor, and the window slightly opened. Loved seeing your son get to be a part of it too!

Love your show! Well....I tried various projects like this in a room that I let get down to a true outdoor temp of 25°F. It didn't make it past freezing. Just wanted to tell folks to find an alternate heat source like a mini propane heater so they don't end up with hypothermia. I bought a Mr. Heater Buddy and an adapter hose WITH a filter to hook to a 20 lb tank. I used it on the low setting and got 3 days of heat for an 800 sq. foot area when the heat went out. Kept socks and sweats on, but putting it on a high setting would have cut down on my days of heat. I keep 3 of the 20 lb tanks filled for my "just in case" event.

Thanks for the effort and thought put into this video. Sorry for the negativity that some people seem to have to introduce to a well intended demonstration. It's a very good idea. For those who don't like it, yeah we all have issues. The whole thing here is to be somewhat creative , and to do what you can to not freeze..not to cut others down. I can think of a few different ways to provide heat in different situations. I had suggestions, but nah..im good. Once again . Thanks for the great videos

these do work well in a small space. I like my flame closer to the bricks/rocks so id lay the top side brocks on their side and then double the bricks on top. I use cookie tins filled with stones and sometimes set a small pot of water on top of the stones

If you look closely at a tub of Crisco brand shortening you will see that the dot on the "i" of the name is a flame. That is because Crisco has a duel use. Doh! Crisco was and is still used as an alternative to candles. Great video!

I was sooooooo curious at how the terra cotta pots worked. So I put some together, lit a crisco candle underneath. Left it going in my bathroom for 4 hours. I could not believe how impressed I was when I checked the temperature and realized the temperature actually rose 5 degrees!!! I did not have the heat on in the bathroom. Thanks for the videos!

I showed this to my ladies group. They were amazed. Good info with going into a dark winter.

Thankyou I displayed these crisco heaters last winter when Texas was in trouble. 1974 -50 in the Yukon it kept myself and 3 siblings alive. I made just the can and candles love the brick idea. So glad you went into such detail as I was bombarded with such ridiculous accusations and

Wow, this is fantastic. Thank you for sharing. Our energy prices in UK are doubl ing this year. For many it has already gotten to making choices between heating and eating. It is a blessing we face warmer weather to give us time to figure out how to survive the winter.....tough times !!!

I LOVE watching Riverside Homestead Life videos! Thank you for showing these helpful ways to keep from freezing in an emergency situation. Stay safe everyone.

I tried this last evening in my hoop house where I’m growing lettuce. I have a thermometer in it that I can read from my house. The bricks didn’t get warm at all. It seems like the terra-cotta pots warm better than the bricks. It’s supposed to get really cold tomorrow evening so I’m going back to the terra-cotta pot method. Thanks for all you do.

Glad to see your involving the young man as you show us the results of this project....Thanks for your efforts...

I made a crisco candle out of a ceramic egg cup for use in the microwave. Fill it half up and when it's lit the cup heats up quickly and stays that way even after blowing the flame out. That lil thing kept me nice and warm on a -20f night when I ran out of propane in my 8x27foot motorhome. I had 3 terra Cotta planters that I had set up as a radiator as well that sat on top of that candle. It worked amazing and was still burning in the morning when I got up

just need to change the design of the brick tower. remember differing temperatures cause draft. arrange the bricks so there are small gaps at the base, allowing for the introduction of cold air to the heat source, build the tower like a chimney stack around the tin, either square or circle, no gaps. at the top have 4 small blocks in the corner's and a tile capstone allowing the updraft to suck in from the bottom, up the shaft and get pushed out in four directions.

I did almost the same setup, but I used 4 regular candles. #1. I have found the candle w/standard wicks cause the flame to be very small and when you pass them, they may blow out. #2. I will go to a hobby store and get cotton wicks for candles / thicker may / will be better (1/4"). #3. With a larger wick I will place at least 2 bricks on top, in case it smokes. The porous brick will help. I will try 1 with a 24' by 24" square concrete paver that may have more radiant heat. I like your thoughts and Ideas. Well done, Sir!

In 80s b4 O2 CO2 sensors , I used those candles to keep Warm . Warm in Extended E350 with R3 insulation . Front cab was separated by 2x blanket covered by construction plastic . Stayed 60+ in 20 degree nights Often got week plus use .

A while back I was given a small container of Crisco, and I had no desire to use it for cooking, but considered hanging on to it for this purpose. I have purchased a candle wick for it specifically, but I had no clue of the potential performance of setting it up and using it, but now I do.

I've made 6 crisco candles 🕯 since watching your videos. Thank you !

Very interesting. A couple of mods that came to mind: 1. Maybe shorten the height of the brick tower to create more stored heat. 2. I think I would probably wall off a smaller hot tent type area to heat more quickly and efficiently. Great idea! I'll be making some crisco candles this weekend.

I like this man's video it is probably among the most accurate . I read thru many of the comments & a uniform thought was to cover the doors & windows . That is so correct but this is my thoughts on how to do that & it can be done YEAR AROUND . I don't remember where I learned this from but I do know it has been over 30 yrs ago....... I use bubble wrap to cover the windows & over the frt door . Yes , bubble wrap that we use to protect our things when we move . I always have to tape it together with clear packing tape to make it large enough to cover them with. It has a VERY SMALL r- value , maybe an r3 to r5 insulating value , not much but it does help/ make a difference. It helps with heating in the winter & cooling in the summer . When I take it down I roll it up & store for the next winter . Several of my neighbors thought I was nuts for doing this now all but 1 of them are using it also after trying it for 1 winter . I hope this helps those that live in drafty old homes like I do .

All I can say is WOW!!!!!!!!!!!!!!! I've been into preparedness for a long time but did not know this simple method...cannot thank u enough..God bless u & your family!

the yellow flame in the crisco label stands fir crisco being used to make candles years ago. as well crisco was also used in mechanic shops fir the freeze. and that's why I use butter in recipes than crisco.

I did this year's ago..made my little fireplace..loved it

Excellent demo! Good info on crisco burn temp, no odor and the added carbon monitor. Just an FYI, the little coconut oil candle I made in a 4 oz mason jar. I added tooooo much essential oil and it did catch fire. The lemon and orange smelled great for a while, but it started popping and then the whole mouth of the jar was a flame. 🔥🧯🚒 Fortunately, I had it right next to me to monitor the burn and quickly extinguished with the lid. I would estimate that I added 50 drops and should have known better🤪😲🤣😂...livin and learnin. I'll be making more lil candles and divide the excess fragrant oils to a few drops each and see how that goes.

Great job wish u put one more candle.but great over all..The Mexican way to heat a house fast is to boil some beans! Back then.not kidding and a flat metal pan to heat the corn tortillas.. I'm old school 59 years old.. blessings my amigo!!

LOVE that fact you have your son involved.

So the key is to light these as soon as a storm is heading in so it stays ahead of the cold. It’s cheap enough to do so if you were to lose power, it will continue to stay warm rather than the time lost trying to reheat.. Thank you and beautiful family 💓

Thank you! I wasn't aware it would take several hours to get warm to 60°. That's the temp I like anyway. Setting this up today. Lost power for 15 min. IDk why. Better to be prepared. 😁I haven't turned the heat on this year yet. It's been 30° twice and inside my house, 55° so it's insulated well.

Just check out some videos on vegetable oil candles and diy floating wicks. Because you can also use a piece of wire to hold up a piece of cotton wick to the top of a vegetable oil candle. I have tested this. Its fine. It will burn a long time. Thats all you need. Like an olive oil candle lamp but olive oil is expensive. Just use any cheap vegetable oil and use any old cheap can. I have tested all of these. Its fine. Close your door and windows or you'll freeze to death and blow your pipes. You could even use a fancy feast cat food can to make a small candle, and put those under the sink in the kitchen and bathroom pipes in the cabinet to keep the pipes Warm. Now your affordability toasty.

Thank you for this post, when you covered it before I was curious how much it actually raised the room temperature, awesome! These are all helpful and I thought I was pretty knowledgeable about these life hacks but I’m learning a lot from your channel!

Is that good Dad? What a doll!

I tried your Crisco candles I was using old birthday candles I had ( unused) I found the the wicks in them were only about a 1/4" long. So I thought what else could I use in an emergency. I decided to try a q-tip ( not the plastic kind). It worked great . My crosco candle has been burning now for 4 hours and still going strong.

The National Fire Prevention Association (NFPA) stated in 2010 that space heaters are involved in 32 percent of home heating fires and 79 percent of home heating fire deaths. They advised consumers to keep heaters and flammable objects at least three feet apart and to clean them regularly.

We have a 3 ton heat pump outside of our garage with a lean to over it to keep the 5-6 feet of snow we get every winter. The heater for the house is in the garage along with our water heater. Our oversized 2 car garage (26X30) is insulated with R-19, and is sheet rocked, so even when it gets down to 5-10 degrees outside at night, our garage never gets below 40 degrees. I doubt that we’ll ever have a blackout in our area bc we have 3 dams that produce electricity for all of WA state, OR and as far south as Redding, CA and as far east as parts of MT, USA.

This was the best demonstration yet proving you can store heat in bricks or clay pots and have it released slowly. I would have preferred an additional demo without the bricks to see the degree of difference the bricks make.

Thanks for this video! I live in a 10x14 shed in Delaware. I saw a video that used denatured alcohol to heat the bricks. I'm scared of the fumes from the alcohol. I was wondering how the candles would work. I'm gonna use this method in my tiny. Thank u so much. Tell you son I enjoyed seeing him helping you. !

My woodstove burns wood or coal and is a gasifier.. Wood burns at 500 degrees and coal at 1500, and that doubles when you add O2 = 1000 & 3000 degrees. The first time I burned coal it was 30 degrees F outside and I had to open all of the doors to let the heat out, so now I only burn coal when outside temp is 10 degrees or lower.

Sending warm thoughts xx

Questions: (1) Since you are measuring air-temperature why use bricks? Get rid of the bricks and let the floor-level Crisco stove use air-circulation to heat the room. It's true that the upper part of the room will be the warmest, but that is true of any heating system. A lower ceiling would be effective. (2) While nine hours is a start, it can't be said to be anywhere near a real test. Your outside temperature is 54F(12C where i live) which for us is a balmy day in wintertime. Comments? (3) Opening the door for fifteen minutes does NOT cool/chill the room. The escaped air has a low coefficient of heat, and hence a low heat content. The bulk of the heat is contained in the floor, walls and ceilings. Leaving the door open overnight and THEN heating the air is a more realistic test. (4) Our (local) need for emergency heating is during a mid-winter storm, with winds at 70Km/hour or more gusting to 100KM/hr draining the heat through every crevice. Please include strong-winds in any future tests. That said, a good video; a great starting-point for trials by anyone. I do admire you for measuring temperature against time (although I think that a boost of about 10F is not useful in a real world situation). As well I like your cautions, using a Carbon Monoxide detector, and the notes on scented paraffin wax. Thanks, Chris

@Riverside Homestead Life - A nifty camping trick I use, is to heat the bricks around an open fire outside and bring them back in already hot. This also avoids the accumulation of fumes in your living space. 👍🏻‍

My greatest need would be to have in my pumphouse to use when the power fails ( I have a small heater in there and use heat tape around the exposed pipes), heating a small area safely for a number of hours

increase the height or mass of bricks above the candles it will store and radiate more heat into the room and you will also have hot rocks so to speak to in or under your blankets or bed. being safe of coarse ! had to say it for all the trolls / dummies out there. I like the video , thanks for taking the time. 🍻 Cheers

I used my Mr. Buddy heater on low attached to a 30lb propane tank with a window cracked during our ice storm last year that killed people. Me & my furr babies were plenty cozy. Now, I’m in Montana dealing with temps a Texas girl never felt before! I need something in addition to my Buddy heater that works on a budget. We’re in a smaller trailer, but it is very drafty so I am going to try this Crisco thang and see what we can do - thanks for these tips! 🔥🙏🔥

just a heads up, a candle flame is around 80 btus, a regular 1500 watt electric heater will put out 5000 btus. so what he had in that room would have put out around 1000 btus. a btu is a british thermal unit usually measured in btu/hr

Same principle as the bed stoves built in northern China where it serves as heated bench during the day and bed at night.

Love your videos! Your personality is awesome...and the editing is really good with the music and timing. Your son is adorable! Great video!

I built one of these that took me a week to plan. You need sealed construction with restrictive heat migration, meaning you have to trap the heat within the box. Candle heat input must be FAR MORE than candle heat exhaust output. meaning? You must TRAP the heat inside the box and turn the box into a radiator allowing only "cool smoke" to escape.

Excellent video!! Thanks for making this. And, your child looks EXACTLY like you.

Nice Test man ! We're in Celcius here in canada, so for example, i keep it around 22c (71.6 farenheit ) So having it around 15 is actually pretty good !!! More than an emergency light source I Believe !!!

Who knew?? 🙂I would *never* have thought about doing something like that with Crisco. Kudos to you, though! Crisco is someting that's been a part of my entire life. Who knew it could become a work of art, as well. *Bravo to you!

I see a fair number of these sorts of videos in my feed and without exception, they all lack an understanding of how to calculate the potential effectiveness of a heat source relative to the space it's intended to heat. It's worth mentioning that the bulk of your test occurred during the day, when the sun was contributing to the heat via the window. Once you went from 6-hours to 9-hours, we saw the beginning of a temperature drop. Had the experiment continued through the night, I believe what you would have noticed is that in the absence of sunlight to contribute radiant heat through the window, the temperature drop would have slowly but steadily continued. To save myself a bit of time, I'm going to copy another comment that I shared beneath a similar video on a different channel. That one was using 4 tealight candles beneath a terracotta flower pot, but the same principles apply here: These are relatively simple to build, but they aren't going to heat most people's spaces. The short answer is "BTU's". For a bit more information, consider this excerpt that I snagged from another web page that's trying to help people understand why it doesn't work as expected: ~~~ _"Can you heat an entire room with just 4 tealights? Sure. If the temperature outside is not much lower than what you want the indoor temperature to be, and your room is well insulated, and you're willing to wait a long time. If those conditions aren't met, you can't do it. If the temperature differential between indoors and outdoors is high, and your house isn't well insulated, heat will be lost to the outdoors faster than your candles can provide heat. And even if your room is well insulated, it's going to take a very long time for those candles to do the job."_ _"Look at it this way. According to Wikipedia, a single tealight has an energy output of about 100 BTU/hr. A small space heater, capable of heating a small room, is 5000 BTU/hr. Thus, you actually would need fifty candles to heat the room as efficiently as a space heater, instead of just four. So let's suppose a space heater would take one hour to heat the room up. It'll take the candles over twelve hours to do the job (considering the burn-life of a typical tealight is well under twelve hours, we have a serious problem!). And remember that this is under the "ideal" conditions, where you're not losing heat to the outdoors more quickly than the candles can produce it."_ ~~~ Here's an example calculation from another web page that makes it very clear that a tealight heater isn't sufficient for even small rooms: ~~~ _"Using our formula from above, a 1,000 square-foot workspace with 8-foot ceiling height means you’ll be heating 8,000 cubic feet of space. If the temperature outside is 30°F and you’d like it to be 70°F in your garage, the desired temperature change is 40°F. Those two numbers multiplied by .133 reveals you’ll need a little more than 42,500 BTU's per hour to keep your workspace at 70 degrees."_ ~~~ I'm not sharing this information to put you down. I'm sharing it because if people are going to rely on these kinds of devices to keep them warm in the case where the power goes out, they're going to be mighty cold. And, we haven't even begun to talk about the importance of airflow when using an open flame in a closed space. A fire needs oxygen. If you're in a small space and you don't have an opening to fresh air, the flame is going to use some of the oxygen in your closed room. And if you happen to be sleeping when the oxygen level in the room drops below a certain threshold, it's very likely that you'll die in that room with the pretty little heater that can't keep the space warm. Don't die. Live. Cheers!

I was dying living trying to survive after hardship and this is like being home again....I'm a van sleeper ...not van lifer that's a trendy shit...I'm poor n disabled and this idea of yours brings tears to my eyes ...thank you thank you thank you for sharing I thought I would die frozen sir...hats off 2 you

Very nice demonstration video! I love all the tips along the way. Get a BATTERY POWERED carbon monoxide detector. And telling us the actual temp outside is very helpful to get a gauge on how helpful it would be for us. Also the tip about bricks helping keep the heat lower in the room was a great point. So many videos get that wrong about terracotta or brick candle heaters. The clay doesn't magnify the heat, it just helps keep the heat from instantly rising to the ceiling.

Even candles emit carbon monoxide and soot so make sure you have good ventilation. I made the mistake of testing this for an hour in my bathroom with door closed to warm it up and found a black ceiling and toxic couldn't breathe when I walked in. There's a reason why woodstoves and fireplaces have chimneys :)

We had a bad tornado that had us without electricity for two weeks. It was January! It immediately got freezing cold as soon as the tornado passed. I had children and elderly to tend to. It Just so happened that i had made about 200 china tea cup candles for a wedding. I hung up blankets on doorways and we hunkered down in one room and i lit every one on top my huge glass dining table, it actually helped a lot. We didnt freeze to death. It’s all i had until i could get a generator. But It worked. I was very careful and aware of the danger of all the candles burning but i had to keep my family warm enough not to freeze. I stayed awake anytime the candles were lit and they all got blown out if i ever laid down for a few hrs . But id always get up after a few hrs of sleep and relight them while everyone else slept to maintainer a temp that wasn’t freezing.

My furnace went out during a cold Utah winter. I live on a mountain side that gets lots of snow. I filled two crock pots with water leaving the lids off and turned on my daughter's food dehydrater. This kept my home warm enough that no pipes burst and kept me surprisingly warm.

Maybe one of those heat fans would help circulate the heat better and raise the temp of the room also. Great video

The room is still unpleasantly cold, I think, although not as cold as it would have been otherwise! Nice video.

You could also place a rack over the bricks at just above the flame and heat (slowly) water or soup.

Again, the pots or bricks or tin cans don't change the output. It's the same amount of energy when you just burn the fuel without them. But it's probably helpful to contain bigger fires a bit, for safety reasons.

Special note of interest: It's impossible for the bricks to generate any heat whatsoever. The heat comes from the flame.

using mixed small and big cans one can make excellent small candle lanterns that comes with a heat shield ... great for seeing ones way to the crapper and keeping warm while there ...

Well done Bro. You're the first guy I've seen who didn't create an explosion. I reckon the distance from the fuel to the hot brick is making a difference therefore not allowing the fuel to vapourise. Brilliant 👍

The other good point about this which you didn't actually mention and some people may not realize is that the bricks continue to radiate heat after the candles are extinguished. If you live in the UK the British equivalent of Crisco is called Trex (or a cheaper own brand substitute can be used as you did in the clay pot heater).

A 6 or 9 liter class K wet chemical fire extinguisher would be good for an ignited spill. Regular ABC and BC extinguisher units don't work as well and also cause dry chemical particulates to hang in the air for quite a while.

what a cute lil helper you have , I'm off to find the crisco candle video , thanks so much

Crisco is so much better than any scented candle. Paraffin is super good like beeswax cuz it doesn't give off black suet like scented candles and lasts WAY longer. I lit a bunch for heat the other day and it really made a difference.

Thanks for doing all this testing. It looks like I could use this in my van if I take all the safety precautions that you have mentioned.

Check covering window areas with aluminum, opening at top. A lot of sunlight and you'll get a lot of heat!

I'm from texas wish I knew about that during that bad winter..thank you .definitely gonna try it

Candles are only about 125 watts of heat, all the bricks are doing is providing thermal Mass to capture heat in an isolated area and slowly releasing it... you get no more heat than a candle... your drywall will absorb it just the same...it's just harder to warm your hands with

Could also use an eco fan on top of one or all of those candle set ups on a metal cover rather than a brick to circular the air rather than just radiate off the brick.. nice vid though proving yet again that in rough times we can use many things to make times better..

If you’re freaked out, you could buy bees wax candles. Probably a bigger issue might be the lead based wicks. Get candles without lead wicks. Then you can focus on surviving the emergency rather than worrying if you’ll get dementia 40 years from now.

I'm getting it done. Thanks Cohen.

CHICKEN FEEDER 2 Weeks ago I Offered a suggestion - update. Found a chicken feeder at Big R Store. Put a wire mesh on the bottom and on top to hold the bricks as it is the same size as the fire prof bricks. Coffee can inside, used "L" brackets to hold in place. Stable, Has air flow, not hot to the touch anyplace at any time expect for the bricks on top. Handle to pick up and move around. Flame is 4 to inches to the top of feeder. Cost for feeder is $25 add $8 extra for misc. costs. Easily use 5 candles What is nice is I can change out the # 10 can for smaller cans like a 48 oz type by just lifting the large can, changing the L brackets put in the 48 oz can and go. Oh for fun I added candle color that I got off amazon to the Crisco. Just lines of two colors not all of it.

I think you would have had higher temperatures from the bricks if you had reduced the distance between flame and brick. Stacking more brick on the upper levels would increase mass, absorbing and dissipating more heat.

Dude. All you need is a can full of any cheap vegetable oil. You need a floating wick. A wick can be anything cotton. A strip of blue jeans, a strip of a cotton dish towel, a piece of cotton rope even off a old mop. Jute twine. Even an actual lamp oil wick. Take something that floats. A 5/8 inch slice of cork wrapped in foil, poke a hole in it run through a wick, wet the top too stick it in a can and light it. A beer cap upside down floats. Also an empty tea light container floats. Same thing. It will float. Poke a hole from the bottom going up. Only as big so the wick doesn't fall through, wet the top of wick and light. I have tested this many times. They also sell floating wicks on Amazon. They are they Jewish hannaka type. Its a little round disk, the bottom is a thin slice of cork. The top is some sort of metel and a small cotton wick. But homemade ones I think are better. You can have a thicker slice of cork. Its not toxic you don't have to open the door like that there's no carbon monoxide. Its way cheaper.

I take this video as a debunk. Thanks for this. I will now scratch this heating process off my list.

I'm glad you posted this. I made 6 of these and 2 with lard. I experimented a bit but didn't want to use em up. My tiny house is 230 sq. ft. with 8 ft. ceiling so I should be in good shape. I didnt think to crack a window. I didn't get any odor from the candles either but they sure stink when you blow them out.😨

If you wanted to get the maximum heat out of them candles, you had to bring the top brick closer to the flame. You had to put the first layer of break on it’s belly and other two on their sides so you bring the top brick closer. Radiation heat not candle power heat. Good videos.
