CLAY POT with TEA LIGHTS Room heating, how to build a clay pot, do they work,tea light ceramic pot...
There is a debate on whether this works or not.It can be either radiation or convection.It's not as effective as if it was convecting it.The original designs I found online had a hole at the top which allowed more convecting.It's a little cleaner and easy to use.It's good for your desk because it gives off a little heat.While I'm on Instructables, I keep mine next to my keyboard.
If you have big washers with a small hole in them, you can use 5 washers total instead of 10.There are two large nuts.If you want, you can use a small section of a pipe.In step 4 you will see what I'm talking about.

It can be made to fit over a light bulb instead of using an open flame.You can change the wattage of the bulb for different heat levels and/or use a 3 position sockets and bulb.

Would this work with metal instead of ceramic pots?I'm wondering if a metal bowl would be less fragile to carry in a vehicle.

It can be done, but it is not as efficient as using the clay pots.The clay pot will hold the heat better than the metal.The pots are similar to a sheet metal stove.

I have used plain, metal cup candles from ikea.I decided to use a plastic cup with tea lights and it turned out to be very dangerous.The pots were blackened and the flames were up to 12 feet high.I tried to blow it out, but it wouldn't lesson.I put flour on it.I put a dish towel on the fire.I didn't think the tea lights would cause this.Feel free to tell me what happened if you have an explanation.

You can make flour explode if you throw it on a fire.You can make a bigger fire.Baking soda can cause a fire.If you want to smother it, use a fire extinguisher or a solid metal bowl.If you only have a dish towel, soak it in water first.

If you want to understand how it happened, you need to know how candles burn.The wax is burned and evaporates.It can become hot and burn like oil.This can cause a fire if any of the wax spilled over and onto play form.If you want to keep the candle wax cool and not ignite, make sure you have plenty of air and clean up the spill as soon as possible.The small glass tea light candle holders from the dollar store are something that catch the spill.

I modified it a bit.I flipped the base plate upside down after drilling a hole in the center.The best hand warmer ever was copied by me and it gave off good heat.I drilled a few holes in a tuna can and mounted it over the small pot to see if there was a difference.Hot air flows from the top of the pot.I think it warms the air nicely.There is a noticeable difference in air temperature.One is a great hand warmer.

This would be an inneficient method to make this heater.

For anyone coming to this.Don't bother with it.There are a number of reasons why this is useless as a heat source.The amount of heat that can be put out by candles is very small, about 35 Watts per hour, because they have energy trapped in the wax.It would take about 43 candles to compare to a 1500w electric heater, which costs about 10 dollars per 100 candles, and lasts about 4-5 hours.$4.30 is needed every 4-5 hours to heat a room.There are dangers you have to face with 43 lit candles in a room.It's also necessary to have a place to put the 11(4 candle) or 14(3 Candle) heaters around the house.The 1500W Heater, some of which can be found for as low as 150$, can heat up an entire 1500-1750 sq ft house.For the cost of electricity in your area.If it's on full blast all the time, it will cost about 21 cents an hour, but they only turn it on when needed.A 500W-750W heater can be found for 25-75$, which won't offer the same heating power, but it can heat up a decent sized room and keep it at temperature.It's even cheaper to run these, and might suit your needs better.It would cost about 7 cents an hour for the 500W and 11 cents on the 750W.If you live in an area with electricity prices between 30 and 40 cents an hour it will be cheaper to run an electric heater than a Tealight one.You should look into a Kerosene Heater if an Electric heater is out of the question.The fuel can be purchased in large quantities.It still poses many risks, Fire, Air, but if used safely and properly it offers little to no risk.It's great for areas that don't have electricity.It can't be that dangerous because it's only used in Japan in the winter time.Don't use it.Depending on where you live, there are other options.A rocket/jet stove is a wood burning stove.It's pretty much heating wood up to very high temperatures.The smoke stack gets incredibly hot because of this.It allows you to heat rooms with a small unit.You can heat water by wrapping copper pipe around the chimney.This is an incredibly efficient way to heat houses and water, though it requires a proper design and place to put it, so I took the time to write this.I'm not telling you not to make one, but there are other ways to heat a house/room/garages that are more efficient and cost effective.To be honest with you.The Tealight would not be able to heat up a small bathroom.The Terracotta pots don't offer much except for a small amount of heat.It's cheaper and easier to just burn the candles on your own.

The candle's amount of heat remains the same.Similar devices are a waste of money.It's well-suited for candles that are so small.Excellent air convection is what it is.The candle's thermal capacity is between 30 and 40 Watts.They can't be near each other.They light directly paraffin and do not have a wicks.The flame may be a fire.It's best to burn low in oxygen and strong smoke.I tried to microwave it.It is difficult.There needs to be a boost and constant control.A computer translation.

I'd like to point out that what you have built is not a heat exchanger.The idea is that the smaller pot is meant to warm up and catch the heat.The heat warms the air between the pots.The warmed air is supposed to escape the hole in the end of the pot.This in turn draws cooler air up from the bottom, thus cycling all of the air in the room past the heating element.
The hole was sealed.The heat from the two pots goes into the room.Radiation is more efficient than convective.Is it a good idea to redesign your method of attaching the big pot?Is it possible to add bolt feet standoffs like on the tray?The main hole should be left open to allow for better circularion.

It was very informative.Thank you for the post!I'm going to try and go for more of a convection than radiation.
I want to make sure I'm on the same page.If you want to fix the pots together, you should keep the main central bolt, but end it at the bottom of the small pot, and use three bolts, like the legs of a plate, instead of going all the way to the big pot.The big pots hole could be opened still.The heat gets trapped in the small pot and spills out into the big pot, which comes out of the hole up top??
Do you think it would work if I just drilled holes on the top of the pot??

You got this wrong.The candle flame is supposed to be under a bolt with washers inside the smallest planter.The washers will be red hot.That's where the heat comes from.Warming up a room with no heat is not possible.I want to heat my garage office in the winter, so I built two different versions of this.It didn't make a difference.

I wouldn't say it's all wrong, but the steal is very hot inside the ceramic pots.I'm seeing higher readings off of this thing.I wouldn't call it "all wrong".It looks better on a counter than any other version I've seen.I keep it next to my laptop because it keeps me warm when I'm online.
