Rocket Mass Stove Question

I am currently building a rocket mass stove to heat the perimeter of my greenhouse.

I am using 6" single wall stove pipe to channel the exhaust, and was wondering what the maximum length should be.

I consulted Ianto's book and he indicates a range of 32 to 40 ft.

My run will be 40 ft with 4 90 degree turns.

Does that seem reasonable?

Thanks,

There are many variables but as a general statement 40' can work for an average rocket. Use tees instead of 90's so that you have cleanout access.

Dear Lasse,

Greeting from the North Cascades. My current design is to put in a clean-out at the front, and also below the chimney. The remaining flow will be routed through 3 runs around the perimeter of my greenhouse.

Do you think I need to add clean-outs to the "battery" portion?

When's breakup this year? I've heard it was quite the winter for you,

Best,

KT,
Cleanouts are key for long term maintenance. Any flue run needs to have an opening where you can stick a flue brush/shop vac hose into to clean even if it isn't that often. I only need to open mine up and clean every other year unless I burn less than ideal wood (I only had to do that once to learn that lesson). I thought one of my runs would be accessible from one end (it has some twists and turns) and when it came time to clean I found out that I really need another cleanout so now I have to add one after the fact which is a pain. So, if you have any u-bends to do, make them H's with two tees and you have cleanouts or figure out what it takes. Breakup is kind of starting I guess (it is melting a bit in the latter part of the day these days but we still have feets of snow!). Yes, what an awesome winter!
