of course, we all know that story was just balls but did the rounds anyway. at least one serious paper made the point that:
a. he had a pc on and, in the old days of his CRT, he could've grown tomatoes in there, and
b. it makes no difference if you heat the brick or not, convection current or no, you can't make more heat from a flame just by wishing it otherwise we'd have power stations running on plate sized ikea tea lights and could forget about nuclear power...

I think it is a bit more complicated than that. It is about creating a slow consistent flow of hot air around the room rather than heating just one small area. Saying that I am no expert and I could be talking ****.

Worth a try, what can it hurt (think i'll make sure I stay in the same room though incase the plant pots explode)

I was just reading about this. Here are some links I stumbled across:
skeptics.stackexchange.com/que…hts
uk-preppers.co.uk/for…717

Seems that it does help distribute the heat (so you don't just get a column of hot air above the candle) but seems to work out only marginally less expensive per watt than a gas heater at 1p per candle (and these are 2p per candle)

Of course, it could be useful if you don't have gas heaters or you just want to heat small areas of your house at set times of the day but it's not the solution to our energy crisis

Been using one of these plant pot heaters for four weeks now. Takes the edge off the cold enough for me to feel comfortable. The candles heat the flowerpots, which hold heat for longer and radiates a greater surface area. Works for me until I get a good deal on an oil radiator.

Short burn time of around 3 hours. Decent value for money though.

How has this reached 283 degrees of heat when the candles are ALWAYS £2 for 100.

candles put out about 30-40 watts each, most of that will be heat, so if you had 4 candles* I can well believe it would raise the temperature of a room by a few degrees. You'd need a lot of them to heat your whole house though.

It's a bad idea for other reasons - fire hazard - and potential health issues

*I tried with fork handles, but it didn't work..

knicked from someone cleverer than me over in a broadsheet:

Assuming 4 tea candles with a combined mass of say 200g (just the wax & wick). Assume 40MJ/kg typical (Kaye & Laby)we have 8MJ of energy stored. Burn time = 8 hours (28800 seconds). Release rate of energy = 278 J/s or ~0.3 Watt.

thanks, monabri.

not that clever! the watt is defined as 1 joule/second. So 278 J/s would be 278 watts, not 0.3. If it was 0.3 you could put your hand in the flame without getting burned.

I make it 800000 joules per candle, burning for 8 hours = 28 J/s = 28 watts

what a joke of a company do not order from this company
