Heating a room for 8 pence a day, brilliant idea!

It's all pretty pointless. Unless your room is very small and super insulated, tealights will do virtually nothing. Even at best with 8 tealights over 8 hours, you are only going to get about 150W/hour.

Not to mention you cannot get 100 tealights for £1. I have looked.

Haha of course it has.

But no matter what, the heat created will be the same, flowerpots or not.

I have tied this out this morning. Started at 8:38 with three candles and two ceramic flower pots just as the youtube clip-





A few hours late and the candles are still burning and the room has heated up a little. It was 5c out side last night and there has been no heating on in the home today.



Holding my hand above the pot I can certainly feel hot air, I get how the second pot draws up cold air and it is heated by the inner pot before being pushed through the hole.

Several problems.
What's lighting those pictures?

'No heating' - heating through windows, especially into unheated rooms - even through somewhat indirect light will dwarf the output of the candles.
The room may be warmed from adjacent rooms, airflow from heated parts of the property, geothermal heat from the floor, heat from the sun on the outside walls, and many other things.
To have any semblance of a decent test - you need to add a windowshade outside the window, and then log inside and outside temperatures over the day, as well as winds.
If you have two closely comparable days, one with the candles on, one off, then you may measure something.

Also - you can't be in the room while this is going on.
Your body heat is larger than the output of 3 candles.
The sun shining through a window for 20 minutes may exceed the total heat energy output by the candles.

My home heats up during day if we get some sun through living room south facing this is without heat. This morning at 9.30 it was 17c now its 19c. I really cant see how this can work using plant pots yes there be some residual heat from the candle with or without using plant pots

It's flawed logic I'm afraid - tea lights are now £1.75 for 100 at IKEA not £1. True cost is now 14p a day!

Does that now make it the big 7, now that Ikea have nearly doubled their price?!

My living room was 19 °C without heating this afternoon with a west-facing window. Won't always be as sunny as today though...

Does anyone know if this would be worth trying for someone who has no heating at all? Even if they are just sitting next to it, so it only needs to warm up a smallish area around it, rather than a whole room? Surely it would be worth considering trying rather than just wearing lots of clothes in a freezing cold room. And I'm assuming that you would notice more of an effect if the room was freezing to begin with.

What about the carbon monoxide levels rising, I would like to see that heat a room up today when its getting pretty cold. My fingerless gloves have been in use today, he had his fleece on filmed in mid october on a mild day probably
