Some standard Finnish contraflow designs & origins

[rakettimuurari]

Hi all,

I thought to share some freely available contraflow designs, which have been quite helpful for me
in figuring out some structural & operational basics and cruxes in my own build.



About the contraflow system background: Origins     (google translator manages somewhat well here)
                                                             
Operation:                                             More about the operating principle

Drawings & instructions:                         Contraflows: Finnish web-page "brick-info"


Here in Finland the contraflow design seem to form the overwhelming majority of all heater installations in the houses used all around the year. 
Personally I still have a bell design yet to be seen here.


Stay warm!

I would love to see your design if you have any of it digitized. I've been looking to borrow some of the contraflow designs into my build this summer.

Hello Gadget,


U can find my plan here: donkey32.proboards.com/thread/2308/brick-sidewinder-riser-baking-oven

It is more of a batchbox than contraflow, but I used some structural conventions common with cf's.
Works 110%. Has kept me warm during this coldest winter for decades.


Happy planning!
