There are many variables I have seen of this Cornish heater, I could experiment with the gap but I just based in being able to put the tea lights in and out with ease.
- Instead of those Tealight Candles (200/box @ $35.00 burning 8hrs each....... Great Value Crisco 3lb tub would be sooooo much cheaper /month..... Tealight Candles are about $60/mo = $720/year....... 3lb GV Crisco would be ~$18/mo = $216/year................ SAVING over $500/yr....... 6lb GV Crisco would cost even less. (those figures are based on 4 tealight candles not 5... ) I hope my figures are correct. there would be 3 wax candles in the 3lb GV Cisco tub (or put veg. fat into large coffee tin.)
Obviously, there is one fact that you have overlooked. The tea lights have a measured and consistent amount of energy stored, it doesnt matter what you do with that energy it will not ever be more or less just the same, so maybe this experiment is somewhat pointless?
You could take that approach but remember a gallon of petrol has a finite amount of energy but it can be utilised efficiently or inefficiently in different vehicles.
@TheRepairer Doesn't change the energy density, does it? Your car analogy is a good try but as there are almost infinitive differences between motor vehicles, therefore variations in performance and economy are equally infinite. Burning a candle to produce heat is a simple one dimensional experiment for which the variables are virtually zero. Sorry but your experiment proves nothing but the fact nobody paid attention in physics class.
I’m sure surface area has a lot too play here. I have a few exposed tea lights lit beside a tea light heater , the tea lights on there own did nothing but supply me light at night, since adding the simple tin box tower heater I can physically feel the heat when near them. The energy is wasted when just let too go into the atmosphere, this is transferring that otherwise wasted energy into something else
The experiment encompasses all of the above principles, the objective was to discover the best design for optimal heat output and retention with a finite energy source.
@@TheRepairer i have, in several variants. fortunately for both of us, there's people here on youtube that have done the same variants and a few i haven't tried yet that are more photogenic than me. OCD and nitpicking aside, my last sentence is your fatal flaw in this vid. that and the fact that your only getting out equal or lesser energy than you input its the overall fatal flaw of this design. the only verified benefit is as a thermal mass storage like a sand battery, but the heat transfer requires close proximity due to the low input/out ratio. air is a terrible conductor. hense the "air gapped" method for various types of insulation. in this case, your about right with 3 pots depending on thickness, but the more spacing between the greater the diminishing returns with regards to heat retention regardless of the vortex effect due to heat loss over distance and time. check out things like the mass heaters and sand batteries for a better idea of thermal bridging. one of the best thermal materials for space heating has always been soapstone which is why the finest stoves and heaters centuries old used it and a couple fireplace manufacturers still use it. so, with all due respect, you had the right idea, but a flawed delivery. in a positive note tho, you did get more right than wrong. if your considering doing an updated video, i'd be more than happy to help you separate the wheat from the chaff. so far i've yet to see Anyone do a comprehensive video. as for me, well let's say it's a good thing i don't have a camera. you might say i have a face for radio and a voice for print. compared to me, you da man! 😎
@@fatherfoxstrongpaw8968I really wished I could understand more than 30% of what you say 😅 or at least enough to get a clear tip on what matters when building a candle heater or if it’s worth it at all. :)
EXCELLENT video... This is EXACTALY what I have been looking for, for weeks! Thank ya, Thank ya, Thank ya,!!!!!!!!!! (as Gomer Pyle would say)
I’m really glad you enjoyed this video, thanks for feedback.
Great to see this experiment!
Thanks, I enjoyed knowing the outcome.
I love my heater it really makes a difference to the room temperature
Most of the heaters I've seen like this have had the pot completly covering the candles with no gap.

Good point, the cheaper the better for energy!
With 5 it started to smoke
So basically they're all a waste of time
I’m using one right now from that batch to heat the living room!

Research radiators.
do some homework on thermal mass , thermal transfer and thermal dynamics in general. supposed to heat the air and not the pot??? 🤣🤣🤣

@@TheRepairer poorly
@@fatherfoxstrongpaw8968How would you have done the experiment differently then?
