Thanks Satamax, I checked out both of the links and I like the setup. I do have a couple of question: is the first part of your build what is called a bell style? and if so that is what I'm trying to build. How much of a difference will the box to the right make and how? I understand that it is a collector box. But for the room would it be worth it in a small shop? You guy's have the answers I just have the questions..... Thanks for the help Billy

I'm in the middle of building a batch rocket workshop heater.
If that could give you ideas.
And it started last spring like this.
Thanks Max. That answered a lot of my questions. It was so interesting that I started following links from those forums and ended up reading for a couple of hours. I finally found vermiculite yesterday and picked it up, so that is out of the way. My plan is to start work on the 6" tubing this weekend and get the burner assy. welded up and maybe get it mounted so I can start insulating around it. I will post my progress as I can. You have been a huge help and I'm sure that I will be getting back with you. please lets keep in touch. Thanks Billy

Hi Glenn, I'm not going to build a RMH. What I am going to build is a stand alone vertical bell heater, I have thought about the short term life of the metal J-tube and that is acceptable with me due to the fact that this one is temporary until I get my new shop set up and arrange it to see if I can install a RMH. Thanks for bringing this up though. All advice is welcome and appreciated. Thanks Billy

The combustion zone of a RMH needs to be masonry (preferably firebrick) to avoid deterioration. Ask Max about this, he can tell you about how one of his early experiments died quickly.
You have probably seen lots of youtube videos of people welding up their rocket cores... what you don't see are videos where they show how well those cores held up to a winter's hard use. A few have done this, as a post-mortem showing how they failed.
