I've been doing some reading on heating small spaces with candles and clay pots. It looks simple and I've seen some elaborate setups some even adding small fans. Most of those I've seen on the web use tea candles and clay pots but I've also seen a few that use larger candles. I'm thinking of using this method to supplement the propane heater I'm using. Has anyone tried this method and if so did it work pretty well or is it a waste of time?

I know there is a lot of information out there on it, but it really doesn't work.

Think of it this way, you can't create energy out of nothing. Putting one or more tea candles under one or more pots does not increase heat production. Most people think it does because the heat concentrates in the pots and they feel the concentrated radiation. In reality, you get the same amount of heat if you burn candles without the pots; it just dissipates into the room because it has nothing to concentrate in like clay pots. One tea candle can produce around 30 watts of heat, which means that you need at least 20 to 30 tea candles to heat a very small room, and you have to replace them every 3-4 hours. Also, most candles are paraffin based (think petroleum); burning a bunch of them in a small enclosed space is going to produce a lot of gases that aren't going to help your plants.

Thanks, although I was thinking about using larger candles, such as those in jars and a larger pot, I see your point. Maybe this cold spell won't last very long and I can quit running my heater 24hrs a day.

Chris, I agree with Jim (MoonShadows); stick with the propane heater.

Thanks everyone for the comments. Looks like I'll be staying with the one heater. At least it seems to be keeping everything above freezing. I've had enough of this Texas winter, it's time for Spring now.

I know my 10x12 HFGH is drinking propane and it's wrapped in a solar blanket. I can just hope the rest of this winter gets a bit milder. Smiling

@Eric4home I know what you mean; so far this winter it's like trying to heat your front porch!

I agree -- that's why I don't even try this time of year Hilarious!

We definitely are due for some milder weather -- and guess what? The Weather Channel shows us having a high of 35F this coming Monday! Hurray! Hurray! (that will be very welcome after highs in the single digits and teens lately) And now that the holidays are over it's time for me to order seeds and finalize my garden plan for this year. You know you're really getting old when even winter seems to go by too quickly Whistling
