Thank you for the reply. The elbows were to try to figure out how to get it under the floor and into the center. That's a lot of drag isn't it? It doesn't purr but did when I built it outside before I added the barrel and all the pipes etc. Along that wall is a battery of water filled barrels sunk into the floor quite a bit - I was loathe to move and re-bury them. If I bite the bullet and dig them up I can take most of the 90's out. I'll let you know how it turns out. Thanks so much - this was driving me nuts.

Oh thank you for the prompt reply...I have had a heck of a time figuring out how to post the pics so it took a while...had to find someone less techno-phobic than I - which wasn't that hard:) I'm on Orcas Island just down the road from the Bullock place ( figure you might know where that is) Zone 8b I think and have moved here from coastal CT. - big difference and I'm having so much fun! The greenhouse is 15' (ish) by 30' (ish) and leaks like a sieve. I've bunged up all the holes I could find and have two space heaters running and heat mats on.
My cob is still wet and I haven't committed to covering the barrel yet either because I'm not sure if I have to change anything. My heat riser (not shown forgot to take pic) is just under 3" from the barrel top I plan to bury the ducts for now as I realize that I need a clean out duct in the bed and will have to do that before I commit to that either (hmmm. fear of commitment!). The sizes of everything else is taken from the book and the Bonnybrooke build plans that I bought online. I insulated the heat riser after I sculpted the air channel (shown) and smoothed it out and insulated down to the ash pit floor from the riser. It is insulated with the slip and vermiculite combo inside hardware cloth packed around the heat riser. The clay/sand cap is rounded and slopes BOTH directions...oops. I get a clean burn and it smokes very little (just when I light it for a second)- now that I have added an extra slit brick into the feed and lay a brick halfway over and at an angle. I"d rather avoid having to buy new duct if I can. I'm in pretty deep as it is.
The pics are on a co workers flicker account as we couldn't figure out how to get them on here.


Thanks so much!

Hi, This is my first build and I have it running well but not hot enough. It is in the greenhouse and I am reluctant to cover the ducts with mass until I know I can generate enough heat. I am afraid that my heat riser is too far from the top of the barrel or that I shouldn't have listened to my partner when he had suggested that I should use 6 inch duct instead of 8in duct when I was the one who read the book and should have known better. So... this thing is at my work and it has to work because it is 26 degrees at night for the next week or so and I really want to save the tender perennials so I don't have to buy them again next year which is why I sunk a chunk of my budget into building this thing well. Please...any suggestions?
