Hey Ernie! The idea of woodstove/rocket heater hybrid I was talking about wantimg to try you already did LOL!

I stumbled across your video "wood stove + rocket mass heater = hybrid "

Glad I watched it. You made some points that I would never have considered.

Back to more sleepless nights in the design department

Thank you Ernie for the suggestion.

I shall try it out.

I can handle feeding it every hour.

So make the Feed Chamber as well as the Burn Chamber all 8" ?

Once again, thanks for your help and letting me pick your brain

What I would like to do is build a outdoor sauna with this type of stove that is safe and wont burn the place down with a open feed tube.

I was thinking with that small of feed tube I would be putting wood in all the time just to keep the sauna heated.

Unlike a regular wood stiove where you put a bunch a wood in and you dont have to worry about feeding it all the time.

Only bad thing about a regular woodstove, it takes a lot of wood and takes 3 to 4 hours to get the suana to heat up to 150F to 180F to get a good sweat going

That's why I the Rocket Stove Heater caught my eye. It burns hot and fast.

I may be wrong, maybe the design will heat a suana up to those temps pretty quickly. I am just thinking because of the small feed tube it would take forever for it to reach those temps.

Thank you for this in layman's terms Jeremy.

This helps with my sleepless nights trying to figure the "math" and design of my own.

So basically what you are saying is

Chamber 1 can be any size you want to hold the fuel you want to burn? So it doesnt matter if its top feed like in your drawing or front feed like a regular wood stove?

Chamber 2 has to be smaller than Chamber 3 in diamter to get the "rocketiness effect?

So I could take CHAMBER 1 .. a square style front loading woodstove, cut a small diamter hole or square either on top or on the back of the woodstove (CHAMBER 1)

Install a small diameter diameter pipe or square tubing for CHAMBER 2 which is part and part of the heat riser for chamber 3.

Then take a drum of any size put it over the the heat riser to make Chamber 3 then install the exhaust pipe near the bottom of the barrel or Chamber 3 ?

Clear as mud!?

If you have trouble picturing what i have said Ill make a drawing and post here for you to look at
