This is the third in a series about ways I keep my G.A.H.T. greenhouse warm.
In this video, we'll show you the best way to make a Terra Cotta Heater. This heater is perfect for warming up your greenhouse or workspace in cold weather!
This heater is a great way to heat up your space inexpensively and quickly. It's also great for heating up small spaces, like a closet or small greenhouse! So if you're looking for a cheap and easy way to heat up your space, be sure to check out this Terra Cotta Heater!
As the weather starts cooling down those of us with greenhouses start thinking about ways of keeping the greenhouse warm sometimes we do that by means of an actual wood stove or an electric or gas heater another thing that a lot of people use is something called a terracotta heater basically what that is is vegetable shortening with a candle stuck in it and a flower pot upside down over the top the candle heats up the the clay pot and the pot radiates heat that's the basic idea well I think I have a better way in the sense that I don't just use one terra cotta pot and I don't use a candle let me show you [Music] the fuel source in a terracotta heater is usually vegetable shortening in this instance I'm using Crisco but it's any brand it can be generic whatever the size of the particular tub of of vegetable shortening will depend on the size of the pots that you're using for me I have found that this 48 ounce tub works well um and then what I would do in the past is I would jam say three candles down into the center of that make sure that they're trimmed off so that they're the right height and that would be the fuel source and the heater source for my terracotta heater I have changed this particular design over the years because what would happen is you would jam the candles down in and as you did you would need to use like a painter's putty knife to scrape out all the excess that gets forced out of the tub as you force the candles down in and that's less than optimal and so now this is what I do when I make a new heater for the Terracotta heater so what I do is I try to make out a little space right here in the center of the tub I use some piping that I have from I have a lot of this irrigation piping from when I set up the irrigation on the property and then what I do instead of using candles is I use Wicks from candles you can get these at heart at craft stores or on Amazon I'll leave a link in the description and then what you need to do is I have an old curtain rod and what I do is I place the wicks into this piece of pipe
Next I do is I Jam it down into the bottom
now I have a candle uh that has the amount of Wicks right down into the middle of it and then I just need to use something to kind of poke the the Crisco down around the edges to make sure that it doesn't burn down too quickly
and now you are ready to go to put this into your terracotta heater so here's everything that you need to assemble the Terracotta heater I showed you how to make the candle itself which has got candle wicks inside the tub of vegetable shortening and then you need a terracotta tray with three terra cotta feet that are used to hold Planters up off of the ground these are easily available at hardware stores you can get them online and then you need a large terracotta pot that will fit around that's approximately the same size or slightly smaller than the Terracotta tray and so what I do is I place the candle in the middle and I light it
then the large terracotta pot is placed over this it's important that there's a gap there for the flame to have enough oxygen and then I stack up smaller terracotta pots everything has to be terracotta every last one of these because these get hot and anything else will melt and then there you have it that I have found is the best way of capturing the hot air out of the candle in each of these little Chambers and then you can get a Terra Cotta heater that will last a long time [Music] so there you go that's how I make a terracotta heater now that's not the only way that I heat my Greenhouse I have actually quite a few different ways and I made a separate video about 15 ways or methods that I use to keep my Greenhouse warm in the winter so go ahead and check that out thank you for watching this video and if you have any questions or comments go ahead and leave them in the comment section below and if you like this video you might like these.

Put the Crisco in the oven for 10-15 minutes, and the shortening will turn liquid. Then, lower the wicks to the bottom and let it cool. No pipes or curtain rod needed.
& It Could possibly be put in a taller can so one wouldn't cut as much wick off?? Maybe?
@@travelchannel304 get shorter wicks
@@colinstace1758 get natural cotton cord from a fabric store and then you can just cut it to fit whatever length you want. Way cheaper than wicks, works the same.
What temperature for the oven? Thank you
@@travelchannel304
You can buy a spool of wick and cut them to whatever length you need or you can get wicks of different lengths
Fun fact
Crisco is the name given to "Crystallized Cottonseed Oil." Cottonseed oil was first derived by people through the use of an oil press in order to find a purpose for the excessive number of seeds produced by cotton agriculture. The original purpose of cottonseed oil was to fill lamps and lubricate farm engines.
Then a scientist found that you can change the structure of this lamp oil or machine lubricant by saturating it in hydrogen gas, which gives the unique solid properties usually reserved for saturated fat like butter. Then an aspiring entrepreneur found that you could sell this lamp oil as food oil, and as a butter substitute.
Please. Do not consume Crisco.
for real, its not needed in anything as an ingredient, in 43 years of life, I have never purchased a drop
Or ANY hydrogenated oil.
Then the marketing was geared towards people that they were poor if they didn’t use Crisco so people stopped using lard etc. and started using Crisco
Crisco is fine to eat. Also helps make great pie crusts, especially when combined with butter.
@@mattypantsNO….it is NOT fine to eat! It’s a toxic and nasty slow genocide!
I’m a new greenhouse owner, in Montana. I used your technique two weeks ago, on a night when it got down to 1 degree F (it may have been below zero, but I went to bed and didn't see). I would say it made a 20 degree difference in my 6 x 12 greenhouse. This stove was so easy to build- I did in the middle of the night, with a headlamp. As it was an emergency, I just pushed candle stubs right into the crisco, set it on the gravel, put the largest pot on feet made of cat food tins and piled on the little pots. I have been using thermal mass (water) and need to add more- but that night was just no match for it. With frost covers and the little stove, my plants were saved. Thanks for such clear and easy advice.
Awesome, that's great to hear!
@@WineberryHill it really looked awesome, too. Like a little rocket getting ready to take off.
Bill Gates owns ECOLAB who add poison to over 35 thousand water treatment plants ... they have been adding Palm Oil for 2 years ... to increase viscosity is their reason. ... and less oxygen that was used to purify !
Looks great, can't wait to try it. Does it produce any oily byproduct that stick to the greenhouse glass?
@@rockekoreis3160 I found the inside of the pot got very sooty, but nothing made it to the glass. Be sure to use small pots on the top to trap as much heat and soot as possible.
The cardboard Crisco containers can be substituted with paint cans from the hardware store if you are concerned with them catching on fire, and your windows can be covered with large bubble wrap and attached with water with a little kitchen soap, to be used as insulation, and this still gives your plants light. If one end of the green house has an opening, but blocked with leaves and straw, they will give natural heat to the room. Decomposition will do this, and you also can use it for mulch on the plants to help keep them warm. Also keep a fire extinguisher or fire blanket to throw over everything, and don't let your fuel run too low that it can catch on fire.
I am concerned about the safety of burning inside the crisco or plastic tubs...
How does it catch fire just from being low?
Last winter it hit -22° with -60° wind chill over night. I had just moved and didn’t realize my propane was set to shut off during a power outage. Well, power went out. House went from 75° to 10° in two hours, and dropping significantly. Only thing that kept me alive that night was one of these terracotta heaters I made real fast when I realized how screwed I was. Kept it going with a soda can candle. It didn’t get 75° in the house, but it was warm enough where a few layers of blankets kept me warm. Power came back on 8 hours later. I would have probably died that night if I didn’t have this heater.
Before you comment “you wouldn’t have died!” Or whatever, just know that -22° is no joke and with -60° wind chills you can freeze to death in under 5 minutes without proper insulated clothing.
If the air temp goes below only 64 degrees F, you can go hypothermic and die (if you didn't have clothes on, or very lightweight clothing), so it doesn't take as much chill as one would think to endanger your life.
I grew up in hot, humid E. Texas and now live in S. California. The coldest I've ever been in my life was 4 degrees while camping at Palo Duro Canyon in NW Texas during Winter (I don't recommend it). I can't even imagine temps below 0.
I use 3 of these terracotta heaters, one is just for my parrot. They are my only source of heat when it's cloudy, which is most of the Winter. I live off-grid on solar/wind/battery power system, so on sunny days I can run electric heaters during the day.
One thing I've added is that I put river rocks between the pot layers, and those stones stay warm for an hour after the candles are out. It warms the room by at least 20 degrees after a couple of hours.
Thank you for these added tips and verifying that these candles will not cause carbon monoxide poisoning or anything else that crack pots try to say to scare ppl away from using them. It's safer than burning a candle in a candle holder. With a normal room, a candle is not gonna produce enough carbon monoxide to kill a mouse. So thank you for proving my point to those naysayers
Making a blanket tent in your smallest room can help in emergencies. That way you emergency candles and and body heat will help.
In my unheated and uninsulated wood shop, I use a couple bricks. I'll roast the bricks in the oven for half an hour.
Then I take the bricks out to the shop. Set them edge up and then stack the terracotta pot on top of that with three large candles in between the bricks.
Instant heat, and it lasts for hours
My grandad used to do this in his green house. I use it in my house too. Remember to seat the heater where you don’t have to move it. Once it’s hot you won’t be able to touch it. 👍
Exept with oven mittens
And it's not as if a situation of oxygen starvation/dander to humans is to be caused.
we just use a big compost pile in the greenhouse and that is it...
We had an older apartment with a big window n a cold bathroom, luckily there was a big tile counter connecting the bathtub. The terracotta stove made taking a bath very comfy!
One thing to note about terra cotta "heaters" is that they are heat collector/spreaders. A candle that outputs about 300 btu per wick (assuming 5 hour burn time and Paraffin wax) is not going to magically output more BTUs. However, it will spread it across the entire terra cotta surface and melt your candles quicker.
So basically what I'm saying is keep them away from flammable things, and make sure your candle has sufficient air space between it and the pots to not melt too quickly.
Yup, it's essentially, a thermal battery.
This man uses a large vat of Crisco in a can, not a tiny free standing paraffin candle. Flammable items don't really catch fire from a hot terracotta pot either. What's ur point?
@@brianjustice908 The advantage of a heat spreader is that you can collect or dissipate heat more efficiently, which is the goal if you want to heat a space like a greenhouse. Yes, the same amount of total heat of combustion will be released, but the goal is to dissipate that heat into the surrounding space rather than just to get a small area really hot. Even if the candle burns faster, this is completely fine if that helps keep the greenhouse up to the desired temperature. It's better to need to burn through two candles if burning one candle in the same amount of time isn't enough to keep plants alive through the winter. (Also yes a solar heater or other style of electric heater would also probably be even more efficient, but the simplicity of vegetable oil and terra cotta offers a super low-maintenance and highly available heater setup even when more advanced technology is not available.)
@@ethanpayne4116 it’s a good off the grid solution- so for that situation we’ll worth exploring.
I don’t believe the goal is to create noticeable heat but raising to the general temperature to eliminate the dangers of frosts or chills.
If it saves your plants when you may be relying on them it could be a life saver
@@ahveganpizzabella The point is be quiet and do your homework.
This video is an absolute gem.
I used carbon fiber weave fabric and put the strands in a brass tube then stuck it into crisco in jar. Wick lasts forever and draws oil through heated tube from bottom.
I could use this for heating my tent when camping! I'll never forget a summer camping and fishing trip years ago when it suddenly turned cold at night time. I was totally unprepared for an unseasonably very cold night when we had previously been having a heat wave. Even my labrador retriever got in the sleeping bag with me she was so cold. I never went camping unprepared for weather changes again.
ouch!! Sounds so uncomfortable. I hope poochie kept you warm.
You will smell like french fries so watch out for the bears.
The terra cotta heater you made is awesome and I'm gonna make one myself. Here's a Crisco tip : slowly melt it into liquid then pour it and place your wick and let it harden. This way you get a longer and more stable burning of your candle.
How long does a can like this last?
Best terracotta heater I have seen I think ✅🙏✌️❤️🌍🌈
Now i will share what other use i have for terracotta pots and that is making Ollas. My spelling may be off , and i dont have the link to show so i will briefly explain and hope you find this helpful and so glad to find your channel im very excited now. Ok Ollas are using the terracotta pot and a terracotta saucer to make a long term water source for plants in the ground . You place saucer right side up and turn pot upside down onto saucer and form a tight bond with small amount of cement joining both and then bury beside plants that are to far for your hose or maybe your going to be away and by filling the pot water slowly seeps out over a long period . Please share this idea if you like . Gardening is my passion when people say i must have a green thumb i say no its usually brown , you have to keep your hands in the soil. 🌱🌳🌼
You spelled Ollas correctly. Although you described it very well, an internet search for "ollas for watering plants" will give your readers a good idea of how they work.
Great idea and thanks for sharing. Definitely going to put this in practice.
You are so welcome!
Never saw the crisco vegore just tea light candles but that bid stack of terra cotta is very nice! Power and power outage ice storm saver!
I make portable heater using old tuna can coil cardboard in it pour in some wax and surround it with brick, puts out a whole lot of heat and burns for roughly 2 hours... Low cost to free to make, you can always find old used candles at thrift stores or garage sales for cheap if not free....
Never heard of this before . Wow i cant believe i didnt know this method. Thank you thank you .
This is the first I have seen of the terra cotta feet. Thanks for sharing.
You're welcome
There main use is to put them under your pots to allow water to drain away so plants don't get water logged.
Terracotta pots MADE IN ITALY are true clay most other pots are just coloured terracotta made from some cement mix- I learned this from looking for clay pots to filter water!
I was looking at Crisco a few days ago. Years ago it came in metal cans. Now it is in cardboard with a foil inside. I would be worried that the cardboard could catch fire and the heated oil could the run out and make a mess or bigger fire. I think i would use an old metal can and pour the warmed oil into it.
I would not attempt this unless the container was real metal.
Melt the oil and pour into quart or pint glass jars then add wicks as it thickens so the wicks stand straight up. I braided waxed cotton during from the craft section and they worked great.
I love this idea! Never seen one raised that big like this, makes sense as heat rises 😉
Wow! I like that a lot. And if you have to hang around the greenhouse to work on some gardening, you can put a kettle on the large pot to heat up water for tea or a coffee percolator. Thank you for the awesome vid!
Great idea for stationary heater
Love it!🙌🏼Thanks! I will make one NOW!😂
I love this!
Cool, best use for that stuff I've seen.
Thanks! Our greenhouse will use this...
So simple...sooo effective
The Terra cotta battle continues...😁🤟
If you know this is something you plan to do, i might suggest candle wicks or cutting up a lantern wick but… set the can of crisco/lard in a hot car and just drop the wick in. You could also paint a terracotta pot black and place it into the sun with the lard underneath it.
Also, if you fill and seal the top pot with sand before you heat it, sand will hold the heat longer and it will work more efficiently. I think they call them “sand solar batteries” or something. It just doesn’t cool off as fast as a thin pot would when the flame goes out.
Great tips!
Finally- a use for the lard I skim off my stock!
Brilliant and beautiful! And I love your readers tip to use a fan to disperse the heat and avoid a flash fire.
Thank you! 😊
Not sure that the additional pots do other than restrict the airflow. The BTUs are set by the Crisco fuel. If you want to spread out the time the heat lasts, then set a large terracotta pot on top and fill it with loose rock or similar substances. Anything that will let the combustion fumes through.
very cool! thanks for a clear explanation.
Great video,thanks!
Awesome!
Excellent!!!
Glad you like it!
Great video 😊
Great idea.
Thanks
Finally . . . a good use for crisco. lol
Awesome video!! Thank you!
You are so welcome!
Good info, thank you!
😃👍
Brilliant!
Big diff in keeping plants alive and people warm🔥of course some almost frozen people can live,,like veggies.
I have a few for emergencies. Back up heat for over a month at a decent cost. 👊
I use broken bricks to hold up my clay pots. Or coffee cups. I have trouble keeping airflow and flame going. I will try a smaller opening at the bottom. good job going to center wicks instead of candles. I was going to suggest that but you figured it out. I've been using a smaller clay tray - just a little bigger than the crisco container - and put the brick parts around the edge of it leaving a good gap for airflow. I do like your stack better than layering them inside the big pot. that'll work better looks like. thank you
Neat and ingenius idea! Thanks for sharing!
Glad you liked it!
Well done.
Plus it looks good👍
Thanks for the video. I will have to make one.
Thank you!
That's an impressive greenhouse!
Thanks!
Excellent! Thank you. 😊
You're very welcome!
Very nice greenhouse!
Thanks!
Great video. Lighting, editing and it was to the point! But if I may suggest an upgrade. Take one of your tomato cages and modify it so it fits somewhat snug over the top of it. Turn it upside down and cut it and then tighten it a bit so that it fits flush on the sides of the pots. You should be able to bend the ends near where you cut to into a hook to keep it tightened around the pots. I would also either choose a permanent spot in the greenhouse and then make some sort of system to latch the bottom of the cage to the floor. Alternatively you could make a base for it to sit on with latches to latch the cage down to.
Good thinking!
Brilliant’👏
Loved it. Thanks,
Glad you enjoyed it!
Thank you bro, nice design!!!
Stealing it :)))
Very cool
Very clever!
Glad you think so!
Excellente ☺️👍
Thanks ❤
Squeezing every calorie you can. Excellent.
Clever!
Merci from Montreal, Canada.
Love it. Thx.👍❤️❤️❤️
Thank you too!
Wow! Ty!
Awesome Thank you 🙏
Thank you so so much
It could be useful as emergency heat in your home during a power failure, too.
The carbon monoxide risk might not be worth it, this is best for greenhouses
@@WineberryHill Of course, sufficient ventilation is a must, but the CO output from a single wick in a can of Crisco should be minimal. If you're in any room larger than a closet it shouldn't be a problem. Also, if you have a few house plants, that should mitigate a large portion of that level of CO production. Bring in a battery-powered CO detector (which should be placed near your sleeping level, since it is heavier than air. That said, it beats freezing to death.
@@WineberryHill - How long would that burn before eventually running out of fuel?
It might be a good way to keep pipes from freezing when there is a power outage?
@@WineberryHill As I understand it, it would be the same CO risk as burning a candle, which tends to burn cleanly and completely. Vegetable oil and candles only produce carbon dioxide CO2 (conveniently, a candle emits about as much carbon dioxide as a house plant would consume sitting in the same room).
There would have to be zero ventilation in a sealed space before the candle would use up all the oxygen in the room and begin to produce carbon monoxide. Even then, it would be very little and take a very time to build up to harmful levels if a human was inside the space.
The method he’s presented here is fabulous! A genius way of increasing surface area, thus heat production and retention AND it can be used indoors. Maybe buy a detector, crack a window, or turn on a nearby exhaust fan to feed in a little oxygen if you’re nervous 👍🏻
Thank you! 👍
You're welcome!
Salute from Scotland
Thanks for the great tip bud!👍✨☕️☕️☕️✨🇨🇦🐿
Hello my friend
I liked your style very much
I have a suggestion I hope you like it
To make a cone of wire by welding, like the one used in the tomato tower
This is to contain and prevent pottery from falling😊
So much brilliance in this, not to mention great hair and surprisingly nice pecs.
Thank you.
Clever yes, Thanks for sharing.
I will not use crisco based on its content.
Thanks!
Thank you!
Thank You!!!
You're welcome!
Ive used 1/2" lamp wick. Soak in warmed crisco, add a washer to the bottom, poke down to the bottom with a wire.
Ive seen a metal tub of water, with a lid, on top of the big pot, with spacers. Seemed to work.
Yay now i can make hot cocoa if the power goes out!!! I like your ingenuity
@@cynthiabehr1870 NOW..... swap the Crisco for bacon grease and your greenhouse smells like fresh cooked BACON!!!! :D
That is so damn cool
I know with candles if you put them in the freezer, when you come to use it, it lasts longer. I wonder if this idea would work with your Crisco
I never knew that!
It looks like you could easily modify this setup to become a rocket stove mass heater. Just stick a pipe over the hole at the bottom of the pots, fill them with concrete, make sure the whole thing is tall enough to burn the wood gas completely, and Bob's your uncle. Robert Murray-Smith has a full playlist on his channel that goes into full detail on how to make a rocket stove if you are interested too.
The concept of a rocket stove is to more fully combust the fuel by forcing more air into the chamber. There is a finite amount of chemical energy in a candle or tub of crisco. If you caused it to combust quicker, you'd defeat the purpose of the slow, radiant heater, and you'd blow through the fuel. And Bob's your uncle.
excellant
Thank you! 🙂
Too cool great job.........
Thank you
You're welcome
Very nice.
Thank you
@@WineberryHill I made a couple of those only bolted together several years ago here in Japan and never thought about an inverted cone shaped configuration like that.
i use an old candle votive, criso and birthday candles. i set my candle on an old stove burner under a pot with another burner on top..
keeps my coffee perfectly hot for sipping. made one with tin cans.. gonna use them in the shop while I putter.
Why not, after putting the wicks in, just pour some melted Crisco into the hole and let it cool?
Use copper you can burn dirtier stuff. Carbon fabric too as wick.
tell us more about it?
Going to make one for emergency heat source for power outage in my small all electric apartment!
Be careful
If you put a size smaller in the bigger one first you'll trap even more heat
The fuel source is a finite amount of heat. If the candle burns the same, trapping it more really makes no difference. It is the same amount of energy expended. The only thing the pots do are to help that finite amount of fuel radiate outward more than if the candle burned and more of the heat rose up with the exhaust gas. Either scenario is the same amount of heat.
Great video, right to the point no messing around. How long does the Crisco candle burn?
it will easily burn for a week straight. That said, I seldom need to burn it during the day, and really only need it on the absolutely COLDEST nights because of the geothermal aspects of my greenhouse.
The thing is, just because you add the terra cotta above the heat source, the heat released from the burning of the fuel is not increased. So, the total heat energy released is unchanged. A simple open flame will release the same amount of heat energy into the surrounding air. With a fan going at all times, the heated air will mix and equilibrate just as it would with the terra cotta chimney.
I'm not saying that the use of Crisco oil is not cool, because it very much is. I be it will burn for days!
I don't think increasing the heat is the goal...since there is that whole law of thermodynamics. My goal is the slowing/holding of the heat via thermal mass.
But in a room with human, air must be exchanged with the outside environment or you'll suffocate. The goal of the heater is to hold the heat in a solid/liquid so it can stay in the room and be slowly released.
It is nice to see that at least one person in one hundred paid attention in high school physics.
@@minhducnguyen9276 this is meant for a greenhouse not inside a persons house. If anything the extra CO2 would be good for the plants
Radiant and convective heat exchange are two different processes
An open flame is convective and will heat the air
Hot terracotta gives off radiant heat which heats the mass around it and then heats the air , much more efficient
If you using wooden matches. Put the used one into the crisco. it will make a wic. i do that with candles when the wics kind of drowning out.
Time to warm up!
The terra cotta is basically a heat sink... It will gradually get "intensely hot" and could possibly cause a flash fire... Trust me I know..The way to avoid this is simply set a fan to blow on the lowest pot.. The fans air current will cool the pot
Great tip!
The fan is a great addition. I use a stovetop fan on my tealight heater. 2 x 12 hour tealights keep a constant 65c on the top brick.
@@ChristopherJohnGurr Is this enough to cool the pot? Trying to heat a greenhouse with no power to it.
@@WineberryHill Perhaps a fan driven by the convection?
@@stevenfraser6180 Convection fans run by the heat in order to spread out the air would be really cool. My aunt does this to spread out the heat from her wood fire stove.
How long will this setup warm for?
Always works...3-dawg night...That was a rock band back in the day. Also, the sun is a great way BUTT how to store the heat for day(s)? Underground where the temp stays constant may be a good idea. Opposite principle here...I always wonder if water pumped thru a copper coil lowered into my 40-ft dug well THEN had a radiator with fan blowing across it would provide cooling?
