I used to service fireplaces and install stoves and inserts. I experiment much as you and so many others do. For the life of me I don't understand people who think that the terra cotta pot heaters can't work. Where I live, Mexican chimeneas are very popular. I use one indoors using canles, alcohol stoves and paraffin heaters; all that I've made. CO is well within acceptable limits and I raise the ambient room temp in a 12x20' room by 5 degrees in less than a half hour. Placing a metal bar across the top of the flue with a Sterling motor stove fan on top it makes the room quite comfy, usually about 25-30 °F warmer than outdoors. If I were to put a larger burner in there I am confident that it would get too warm to be comfortable in here. If you've read this far, thank you. PS for the ceramic pot deniers, there's a reason my forge and foundry are both lined with ceramic materials. 😉

A BTU is a BTU is a BTU. The law of conservation of energy applies to the argument. The amount of heat produced by a smallish flame is the same whether you're heating the air (convection) or heating the things around the space (radiant). The BTU output of a candle flame, burning paraffin wax is only about 9BTUs. That's just 65% of the BTUs produced with an electric 4-watt nightlight bulb. A candle burning soy wax only produces around 6BTUs. A typical candle isn't going to create any kind of meaningful heat. However, with that said, Robert is using vegetable oil, which is more closely associated with soy than with paraffin. He also has a flame which is at least 1.5" in height and a wick up to 1/2" in diameter. It's going to output orders of magnitude more heat than a typical candle. For comparison, a typical hurricane lantern with a half inch flat wick can output as much as 900BTUs/hour when burning kerosene. That kind of heating can definitely warm a small room with radiant heat. In 2020, I kept a 125CF polypropylene (PE) greenhouse at 68F when the outside temperature was -10F (a 78F temperature differential on opposite sides of flimsy plastic!!) using a 1500watt oil filled radiator space heater and (3) 1-K kerosene hurricane lanterns to supplement the electric space heater. The argument as to whether a terra cotta pot heater can work or not, has more to do with the size of the flame than anything. A typical candle or tea light candle just doesn't output enough BTUs to accomplish much of anything. The wick is barely a 1/16 of an inch in diameter, and the flame is not much more than 3/8" tall. But if you create your own candles -- vegetable oil, kerosene, paraffin oil, diesel fuel or even vegetable shortening -- with a quarter inch round wick or larger, or multiple quarter inch round wicks, then that terra cotta pot heater will work like a charm. As BTU levels rise, so too will fuel consumption. You'll get the most bang from your buck with diesel fuel, once you overcome its tendency to gel in cold weather.

Hi Robert ! I just wanted to testify that the stainless steel pot idea works wonderful! Up here in northern Wisconsin we recently had a bad and very cold winter storm come through about a week ago or so .Our windchill index was at -45 to -50 °F here and our 106 year old house dropped to 61° F inside .I put 2 big candles with just 6 wicks under a stainless steel pot and over a period of 6-8 hours it raised the temperature by 3° ,which is amazing because we had 40 mph winds and the house gets cool fast when th as t happens. But I'm going to try the carbon felt idea next ,so thank you for the great tip ! Cheers ! 🙂

Some interesting studys on the health benefits of infrared light recently and how it affects the body and the brain, check out med cram. A lot of recent tech advances have removed the levels of infrared from light bulbs and we don't use radiant heaters as much any more. Looking like we are going the wrong way in some respects. Sometimes the old tech is the best. Interesting video, I really like your forever wick design.

I've changed my mind back and forth on the terra cotta heater. I think it captures some of the heat that would otherwise just go straight up to the ceiling and made a spider up there think it was Chinook season. It doesn't add one erg of energy given off by the flame, but it re-directs some of that energy sideways to where people are. It'll feel much warmer next to it with a metal or ceramic radiator absorbing and re-radiating the heat to the side. At first, I thought it might be the heat mass of the clay pot extending the release time of the heat, and it would continue to give off heat after the candle was extinguished, but it'd only have as much heat stored up as its heat capacity times its mass would allow, and it's not really that much mass, and the temperatures achieved aren't really that high. You need a lot of mass and a lot of heat put into that mass to do a whole lot after the flame goes out. I just think there's more to the re-radiation of some of the heat, laterally, is what makes it out-perform a burner, alone.

My uncle who’s an electrician and built his own house chose to install electric radiant heating in the ceiling which was interesting because the air was relatively cool but the furniture was warm and it felt comfortable. His house was connected to discounted unreliable power, so was required to have secondary heat (wood stove) in case of an extended outage.

Overhead radiant heat is much better than heated floors for many reasons, although it does mean you (and your cats) can't stretch out on a nice warm floor as quickly. But we're more accustomed to radiant heat from above, because of the sun, and it does warm the furniture. Added bonuses include much lower installation cost, less wear and tear on the system -- and, if it leaks, you know right away and can get at it to fix it much more easily and cheaply.

Nice! Glad someone could use my alcohol trick. I also experimented using of all things, a terracotta wick for the same reason you used the carbon felt & Kevlar wicks, longevity. However at the end of the day, I decided the carbon buildup would eventually clog the terracotta poors and scrapped the idea for the most part but changing the surface of the terra cotta has an excellent result for the flame 🔥!!! If you decide to use the terracotta wick idea there are some very important tricks to get it to light and to stay lit which I won't bother to discuss unless someone wants to try it. Also, another rock wick I wanted to try comes from a material found in a Europe quarry yard with exceptional wicking properties, but they kept dropping the ball when I tried to order the material. Lastly researched the ideal size of capillary tubes (which I obtained) for moving fluids of thin viscosity a long distance, I found it did move ultra thin fluids but could not get it to light 🕯️for more than a few seconds sadly. Can't remember if I tried the alcohol trick or not. GL and TY for the vids as always!

Be handy to keep the cuppa tea hot. I tried the tea light plant pot heater back in spring. I did the (double pot?) method of having the internal one capture the heat and the external one with three small stones as risers trap the radiation in the gap between them to get some airflow going. Cap off the internal pot and the air coming out the hole of the external was reasonable. Place stank of tea lights though.

@@gabbermaikel I found it to be warmer with the double pot method than with just the tea lights. Four tea lights got the internal pot to a high enough temp to be painful to touch. Spread over the surface of the pot it could heat a larger volume of air. If I was warming my hands I'd go with one but if I wanted to warm the room, slightly, two works better so far as I've seen.

Im in the camp of it does work. I had a few mods to my set up. I used the stack method (one smaller pot and one large pot) My mod was: I used a copper tubing to wrap around the smaller pot and the excess down the center hole of same pot to sit directly above flame. In my head the heat would collect under the two pots, the ceramic would heat up and radiate out, but with the copper plumbing tube being heated directly by the flame the outside pot would be heated evenly instead of the heat loss escaping through the center holes in the pots. I Guess you could say I used the tubing as an internal radiator. My bedroom was only 11 x 12 and I had plenty of furniture to absorb the radiating heat. (Computer desk and chair, book shelves, futon) but it got so hot I had to crack a window(It was the middle of an ice storm 23 degrees F)

Robert - love your channel. One reason the shiny, steel pot got so hot is that the polished metal has a low emissivity, meaning that at a given temperature it does not radiate as much. Much of the heat will therefore remain in the metal until it convects away through natural convection. Maybe a follow on video would be on using pans or pots with different emissivities. Cheers.
@Paxmax
@Paxmax Жыл бұрын
This is basically what I wanted to add, if yer building an radiating heater, shiny is bad, you want to radiate, so one must chose a proper surface for that. Clay probably has better emissivity, using the graphite cover trick presented by Robert in another video is a good idea. Graphite, being black and somewhat matte should be a good radiative surface treatment. Graphite is also such a thin layer it doesn't pose much of an isolator.

I've seen videos where they've used pots. But I liked the idea of using several plant pots because (I think) they'll hold the heat longer. By putting a smaller pot inside with a long metal (hollow) bolt down the center of the plant pot hole, you can ad some spacers and bolts above it. Then place a larger plant pot on top of those and screw it down with the end of the long bolt sticking out at the top. You might even go with 3 plant pots. I tried to set one up like that myself a few years ago, but never had a chance to put it to good use.

Im too tired to make all the calculations but i worry from direct heating some heat is lost from cooling effect of the evaporating alcohol. I guess this is true for all fuel. A friend of mine had 6 guage copper wire running from flame back to the fuel to keep it warm.

I already made a plant-pot heater with 3 pots bolted together and have used it with a range of candles. I used scented candles, DON'T, the carbon that comes off it will stain paintwork. I made my own candles with wax and up to 6 wicks, don't use any additives as they will cause carbon particles to be emitted as they burn. One word of caution the bolt gets exceptionally hot.

You're talking about creating more energy than you're using (which is impossible). I think it's a neet concept and certainly good to know if you're living a small tent in some type of survival situation. . . . but for an entire room I don't believe it's very efficient. You would need many of them.

I think your efficiency of energy transfer from the flame will be much greater if you turn it up side down and allow the flame to hit the stainless steel ! If the flame has to warm the air and inturn it warms the pot you have a very ineffecient step that could be deleted . For best results of effeciency put an aluminium skirt around the pot creating a second skin with a 2mm gap. The hot air coming out the sides will go up the side and travel between these 2 metal skins ! High end camping equipment employs this for best efficiency of liquid or gas fuels .

It would work even better if you painted the outside--would make it more emissive (emissitive?)/transparent to IR (I mean it would increase the emissivity). Then, if you wanted it to heat yourself more specifically if you're sitting on a chair or the like, you can put some convexed material with shiny aluminum surface behind it to direct the IR towards you.

Today I made a heater by cutting a long skinny carbon felt wick, wrapping some wire tightly around the tip, securing the wire across the top of a can of crisco, and shoving the wick down into the center of the can. The wick would have fallen down into the shortening once it melted and that's why I used the wire; I didn't want it to fall in and be extinguished. The carbon felt burned wonderfully. Now I just need to build an inverted dome over the top, but while I burned it, it gave me light as well as a small amount of heat.

I have seen videos where the person was in a van, with 40f / 4.4c temperature outside and slightly warmer inside. after lighting a flower pot heater with 3 tea lights, and waiting an hour, he saw an increase of roughly 2 degrees. He was using an analog thermometer for air temp, and a laser temp reader on the pot which did get up to 200+ f / 93.23+c. Now if you are in a very well insulated house / small room 8'x8' / 2.4mx2.4m it will maintain a temp in the 60's / 15+c if the air is close to that temperature. But again those that say it works always use the laser temp probe, those that don't use the analog air thermometer.

With the right material you can even make a focused beam and heat a particular spot. Just think of those outdoor electric heaters. Aside from simply pulling a ridiculous amount of power, they have reflectors that direct the infrared radiation down toward where you're sitting. If you had a parabolic dish, you might even be able to point it across a field.
