Candle Heaters Do They Work? Here we have a flower pot candle heater.I made this article with the intention that it will possibly save somebody's life.
it is basically a terracotta pot with another one inside and a whole series of nuts and washers attached to a bolt which runs through. Now, first, let me begin by saying that these clay pot heaters are very effective at dealing with condensation in an environment like on a boat.
If I'd been using this tea light heater throughout the night, there will be zero condensation.
They are extremely effective at dealing away with condensation.
The Clay Pot Heater. The terracotta pot on top gets very hot and the bolt here gets so hot that you can't touch it.
In this case, this was attached to a chain because it's on a yacht(out of water).
Now, please take note of this because these are extremely dangerous devices.
The tea lights inside generate about 40 watts each so that's four in there now. So there are about a hundred and sixty watts of heat.
The heat inside gets so intense and what you actually create is a bomb.
The paraffin inside these kettle lights very quickly melts, it turns into a liquid as the candle heater works.
Flower Pot Heater Debunked. Now, let me explain how these are dangerous. These kettle lights, tealights, whichever you want to call them, they should never be less than eight centimetres apart.
In this case, they are near on right next to each other.
What happens is there are two scenarios that can unfold because the wax turns to liquid, the intense heat creates the possibility for those liquids in each terracotta pot to ignite, however, if the wax liquid wax would leak out and get into this tray at the bottom, it then comes down the bar inside and you can never get rid of it.
Now, I had a fire with one of these and that exact scenario happened. The wax leaked out and it came down the shaft of the threaded stud and during the night it flashes and flared up.
The whole thing ignited.
All the paraffin wax inside the saucer ignited and the flames came reaching out all the way up.
They came so high that they actually melted the hook and in the video below you can look at the damage it did there.
It was hanging on a hook and ignited in the night.
It nearly burned the boat down...I am serious.

Flower Pot Heater Does It Work?
The clay pot once it's been running for 10 minutes, you can't hold it, the threaded stud bar there is impossible to touch it without burning your fingers so please, please, please, if you're going to make one of these do not under any circumstances put multiple tea lights in and never ever leave it unattended.Now, as I say these flower pot candle heaters are extremely effective at dealing with condensation, however, they are exceedingly dangerous. You must never ever use tea lights that close together. Now, despite saying this I still use this device because as I say it does deal with the condensation, however, I only use one tea light at a time but even then there is a danger because the heat that gets generated from this the device is really quite remarkable, it is intense heat.
Flower Pot Heater...Test?.....Please do not! The possibility for this to ignite and flash flare is extremely high.
These are not safe devices and even though they may be aesthetically pleasing and very effective in many ways they are totally and utterly lethal.
They are very dangerous.
If you use these at some point the possibility of having a fire erupt within the actual liquid wax itself is extremely high.
These are very, very dangerous.
I had a lucky escape.
Please don't make the same mistake.
