Hi Paul,
I dont think this patio heater idea is something worth perusing. Most of the heat produced rises to the heavens and a portion is radiated downward to provide some warmth. A much better way to heat people outdoors is having the heater as low as possible. A small TLUD positioned under a table, if the is sufficient leg room, provides much more efficient heating. I collected the patio heaters from the recycle yard for their components, particularly the stainless steel barrel housings and the hood. I will be making dual-walled, insulated barrels with them to replace my 100 Lt drums. They will look better and last longer. I think the hoods are also useful to direct smoke and exhaust gases into a flue and away. Even though my patio heater mod reached respectable temperatures, because of the greater the chimney height, the reactor can which would normally burn for an hour, lasted 40 mins or so.

Schoner; Doc Anderson Subject: Patio Heater Conversion was Re: [biochar] TLUD fired BBQs & pizza oven Dear Erich and Hans and all, and jss Use of a TLUD for a patio heater is very interesting, and raises many questions. I hope that this new thread /Subject can stick to this topic and that ... 1. GOAL: collectively we can devise a practical patio heater product with a TLUD as the heat source. 2. But there are at least 2 Listservs involved, so it could easily split. I will discuss with my webmaster James about having summary information placed on my www.drtlud.com website. (I do not want to have the interactive discussions there in the comments sections.) 3. The summary of what has already been communicated is in Erich's comments and Hans' photos (we will want to pull out the 4 photos that are numbers 0186, 0187, 0188, and 0192 .)

I had only posted the picture of the stainless steel patio heater previously, not the exploded view with the stainless steel cook pot and wire mesh & chimney replacing the propane gas cylinder. So now I am keeping an eye out for a damaged Patio heater. I imagine that the photo showing 500°C is considerably more than what the propane puts out. http://www.flickr.com/photos/cheap-thrillz/8034974018/in/set-721576294349812 97/ Erich Also important is the address for Hans Hans Erken <[email protected]> Some questions: 4. Is there a door for inserting and removing the TLUD? 5. How well does it actually heat? And in comparison with the LPG / Propane versions that have more radiant heating, I believe. 6. Costs and durability, etc. I hope that some readers and their friends will study this. If interested, please speak up so that we can identify who could be looking into this topic. (I am headed to Uganda on Sunday for 3 weeks and I will not be able to do much except to read the messages and send some comments.) Paul Paul S.
