    Not exactly sure what the flower pots are for since you are trying to heat the entire room. I could see using them to concentrate the heat to warm your hands over but they don`t create any more heat than the candles already produce so what are they for?

    I like oil lamps. They warm the room and are pretty.

    @ lauriloo, the flower pots create a convection, moving the air and distributing the heat quicker.

    they help the chamber between the big and little flowerpot serves to heat up air flowing in the room, as opposed to just relying on heat produced by the candles. The candles are producing heat but the chamber is also trapping air flowing in the room and warming it as well.

    Flower pot made of clay can retain lot of hot,so they become good accumulators and the air chamber you create allow the air to warm up. Brilliant idea,gonna try that.

    If he`s trying to supplement the heat that was once generated from his old crt, he should just play some video games instead.

    It uses four candles? That can be tricky.

    How much is the electricity cost there that he can`t run a (small) space heater for less than that?! Amazing expensive it seems!

    I pay 20pence a KWh in the day- between 1am and 6am it is 8p. So IF this would work it saves a lot- but I am dubious. Will try as soon as I can find suitable flower pots.

    "How much is the electricity cost there that he can`t run a (small) space heater for less than that?! "

    A small heater in my smaller bedroom here works out about 5-7p an hour - yes electricity and gas prices here have gone up a lot in recent years thanks to the energy companies taking the piss out of us plus them passing on to us all the government`s `green taxes` for energy.

    I`d try this but it`s not really compatible with 9yr old kids running around the house.

    I had to use a space heater a few years ago. It probably cost me 5 to 10 cents (pence) a day to warm my living room (great room). Maybe half that to warm his "office". Looks like a bed with a desk on it lol.

    I suppose the pots help by concentrating and keeping most of the heat lower in the room instead of immediately dissipating and rising to the ceiling. People saying the pots "make" more heat don`t understand the conservation of energy principles. A piece of pottery doesn`t create heat but it can store heat and concentrate it in the area where you can feel it.

    I`m doing this from tomorrow.
    @LordJim- I wondered if someone might post the two Ronnies link. Classic.
    I think I`m right in saying it was voted number one comedy sketch in UK for anyone who hasn`t seen it yet.

    @lauriloo:
    No one said the flower pots were "making" heat as you said. Look at what @Stormith and @piperfawn said.

    You don`t seem to understand the difference between a convection heater as presented and a radient heater like a candle.

    Here read this.

    Yes, that is what Britain has come to. The fact is, quite a lot of people cannot afford to operate central heating in winter this year. This illustrates why I don`t go back.

    Lets apply some sciense:
    Energy content of candle wax = @42kj/gram
    Weight of a chafing candle = @11,5gram
    So each chadle produces @ 483kj

    That dont tell us much of use so:
    483kj will heat 1 liter of water to 115deg C
    If that was possible.
    So his heater is equal to 3½ liters of boiling water.

    So do we think we can heat a room with 3½ liters of boiling water?

    I prefer my heating blanket to take some of the chill out of the air. I would rather deal with an electrical fire than an oil based one.

    A candle puts out ~50 W of heat x 4 = ~200 W. Putting flower pots around them doesn`t make them produce any more heat; however, it does convert much of it into radiant infrared energy as opposed to hot gas shooting up to the ceiling. It`s effectiveness would depend on the size of the room, the outside temperature, and insulation.

    For comparison, a typical electric heater puts out 1500 W (~30 candles) and costs $0.18/hr. to run at full power, based on a rate of $0.12/kWh. If you cut it back to 200 W, that works out to $0.025/hr or ~1.5p/hr, which would be ~12p to run it for 8 hrs.

    Candles, therefore, will heat for about half the cost of electricity. However, electricity is the most expensive heat source you can get. It`s ~3.4 times more than natural gas which will generate 200 W of heat for 8 hours for $.035 or ~2.2p.

    So, candles are cheaper than electricity but more expensive than gas. Plus, you don`t have to drive to Ikea for gas.

    "You don`t seem to understand the difference between a convection heater as presented and a radient heater like a candle. "

    I took thermodynamics classes as part of my chemical engineering degree. Did you read what I wrote about why the pots are there? I understand it perfectly. Read the description of this video that shows the exact same thing:

    Flower pot heater

    The other people wrote it a little more clumsily than I did, in my opinion. This part "as opposed to just relying on heat produced by the candles." sounded like heat creation the first time I read it, that`s all.

    I bought one of those power-monitors and went round the house checking what every single appliance used. My netbox took 275 Watts. (50W in standby). (1600AMD, Iiyama vision master pro 454, etc). After found out that it used about 40% of my daily electricity consumption, I started switching the thing off when not in use.

    The effectiveness of this solution is derived from heat exchange. Direct heating of 1 medium via another is invariably inefficient (i.e. a direct flame) but heating an intermediary is more efficient. The high temperature of the flames heats the inner pot, which being a clay pot has a very high specific heat capacity. It gets hot but far cooler than the flames of the candles. It can `capture` and then radiate the heat very effectively. The air passing over the inner pot is warmed and convection replaces it with cooler air. This is a far more efficient way of heating a space than direct heating. If you allow high temperature gasses. I might have to give it a go.
