I started out with a 8 inch system couldn't get it to pump the smoke outside but sure could blacken the inside if the greenhouse . I could not see 6 inches in front of my face.
Currently I am working very slowly on a system with 1 complete 100 pound propane tank as the feeder tube. Before I continue too far on it I want to listen and see what I can learn from you folks.
I know how to upload pictures to face book/ can any of you advise me of the steps to up load pictures or drawings to this page.
I sure would like the feed back on what I am trying to do. I have as many 100 pound propane tanks as I need and I have been donated a 250 gallon diesel truck tank so I can have more than one insulator tube on the inside before the exhaust has to exit.
However advice is an asset to have from those who have experimented and have got it running up to par. I have spent a lot of dollars on a complete failure and do not want to go done that road again. I bought and installed a double barrel stove with a horizontal chimney and you should see the creosote it could produce. I have it apart just waiting for a trip to the dump! Would like to make something that works. I have a pellet stove but at $5.99 per 40 pound bag of pellets its expensive. I also have natural gas as a back up system for the hot water tank and that is not so expensive. need advice on how to make a longer burning system
Many thanks

I went to the site that you suggested and will return to it later.
I used a 1000 pound Propane pig for a hot water tank as it was donated to me. I welded three 3/4 inch steel nipples to it and added two pumps of which some young Engineer guided me on what to buy. First nipple outlet goes to the pump then to a header which currently is feeding three zones. the second pump / pumps water from the lower end of the tank though 1/2 inch copper line which is loosely wrapped around the outside of a 100 pound propane tank which is the outside of the current RMH that I just built ( my second attempt as the first was a disaster) I can get the water up to 106 degrees F. but this is short of what I am trying to get. I would questimate I am heating 65 to 75 gallons. The main problem is that the in feed burn chamber of this rocket stove is 5x5 inches and only burns for 25 minutes per burn. I am trying desperately to extend my growing season into November. Starting it back up on the end of February.
This is Edmonton Alberta and it gets cold. My greenhouse sits on 6 inches of concrete which is a good heat sink if I can heat it.
I hope that this clears up to you what I am trying to do . I need longer burn cycles and hotter water.
Suggestions and guidance are always welcome!

I will try to address all your topics. I read and research topics to great lengths that's how I found this forum. I do not believe all that's 9th the Web as most of it doesn't work.
I am retired and went through a bout of cancer and repercussions so now have time for these projects like.
I am not looking for any pats on the back to what I am doing as I consider myself a beginner when it comes to these things.
I do however post on Facebook pictures of what I am doing as I get advice from all over the world the items to improve some of the projects.
However when it comes to Rocket stoves there is very little good advice. Lots of cap.
I am thankful for the information that you shared with me. Probably just saved me a couple of hundred dollar bills. I don't build out of crap.
I have a very good supply of uncertified 100 pound propane tanks but the rest of the parts I buy from a steel shop.
Later tonight I will look up the sites 5th at you shared with me. My system has a pump and it will thermosyphen as well but I used PEX between the
copper tube and my tank without the pump it gets wildly hot and PEX will only stand temps to 200 °F.
Please keep the information coming and I will try to find out how to post a diagram for you.
Many thanks

Correction i am using a 1000 pound propane pig for a hot water tank. Sorry i cannot swap it as this size is very hard to come by.
Thank you for the information well appreciated.
what happened to the Rocket Stove that was made by wrapping the copper tube around the top of the J tube? Same results?
The last RMH I built I wrapped 3/8's copper tubing around the outside of the outside drum but it only achieves 106° F. Which is insufficient.
I have this system in my greenhouse, so no danger to family.
I need to achieve higher temperatures in order to warm concrete floors. Also can anyone advise me how to upload a diagram to this???
Sorry but I am not so computer literate. I can however try to learn.
many thanks

I am currently building a second RMH of which I would like to gain hot water from.
I am considering putting the water jacket around the portion of the J Tube where my main fire is. I have a 1000 pound propane tank converted to a hot water tank. Pumping water through the water jacket and into the water tank. Tank has 4 -3/4 inch openings at the tip to prevent pressure build up.
by suggestions for me?
