thanks RS
very similar to the plant pot space heater that S13 posted a while back but even simpler (no need to bolt the pots together)
I found that simple and cleaver too,..thanks
We do that all the time in our breezy National Trust cottage, it works surprisingly well

How to heat a room for 8p per day using four candles and a couple of terracotta pots

Boy! That one must have spread like wildfire - their site's crashed due to 'unprecedented traffic'!
A candle flame produces about 15W of heat
I can't follow the link to confirm what sort of candle they showing (As the link is down at the minute) but a typical tea-light candle lasts for about 3 hours
So four of them would produce 3 * 4 * 15 = 180Wh
Which is the same amount of heat you'd get from a fan heater running for 5 minutes.
So certainly they produce heat but they won't make much of a dent in a big space.
You'd need it to be a very small room if you wanted to feel much difference.
By contrast an inactive person produces about 100W of heat just sitting still (Reading a book or using a computer) and potentially much more if they’re actively doing something.

Enjoy
Have built three of these, two small and on large, they are great. Funnily enough I actually watched that 2 ronnies clip the other day
Pretty impressive economically.
And there was me feeling proud of our frugality of having discovered a source of slow burn compressed sawdust briquettes that give us heat, hot water and cooking for around £ 1.50 per day.......

That's actually pretty impressive!
Our solar set up pretty good at heating up some water and I'm quite happy putting an extra sweater on and eating cold food but, alas, the rest of the family doesn't quite see it that way...
