Thank you Glenn. Can you please tell me, how in the future, I can find post and podcast like you sent me?
Thank you

I understand there are instructions along with a podcast telling how to make an 8" batchbox. Could someone please direct me to it? I can not find it. I know I am a newbie, but I am trying to soak in as much knowledge as possible. I did purchase the Rocket mass heater book and am reading it as we speak.
Thank you

The reason I was going to use the 100 gallon propane tank for my bell for my first attempt at a Rocket heater is, I think since it will not be a MASS heater, the propane tank is thicker walled than a 55 gallon barrel and therefore has a little more mass and may retain the heat better. If my thinking is incorrect, I do have access to a painted 55 gallon drum. Any thoughts?

Glenn, thank you for your reply and information. I do not think I will waste my time using the stainless liner. The cheapest I can find 1.25" thick firebrick is, 6 bricks for $18 at Menards. Are there less expensive sources for these? The more I view videos and read information about Rocket heaters , the more I am confused. It seems that store bought rocket heaters are made out of steel and a lot of homemade ones also, but then I hear/see the stories how the steel even stainless breaks down.
When you say the proportions are 1-2-4, do you mean, the lengths or widths or both, for each component? As an example the feed tube is 6" long, the burn tube 12" long and the riser 24" long all of the same diameter?
Would you recommend for my tank size, to have a 6" diameter riser, exhaust and burn chamber?

Would it be less expensive to mold all components out of refractory cement and perlite?

Thankyou

Hello, I am new to rocket stove heaters and have a few questions. I plan on making my bell out of a 44" tall (w/pedestal) by 14" diameter old propane tank. I wanted to make the rest out of fire bricks until I found out the cost of them. I do have a 10' section of 6" stainless steel flexible chimney liner that I was wondering if I could use that for the riser with a piece of 8' duct around it and fill the space with fiberglass insulation? This first attempt at a rocket heater will not be a mass heater. With that size bell what sizes would I be looking at for the riser, burn chamber and feed tube? Funding for this project is limited so I want to use things that I currently have or that I can obtain locally at a reasonable price. Any help is greatly appreciated. Thank you
