wood burner baffle

[ross1993]

looking to make a wood burner , heard quite a lot about baffles and the increased heat output and a cleaner burn , not to sure what to add .and where to add it , using a 15kg cylinder so access is fairly limited and i don't really want to cut it in half and weld the whole thing back up.


any help ?

i just cut plates approx half the diameter of the cyl, slip them in through the door apeture, and secure with simple, L brackets and bolts no welding usually bout 3/4 way up..sometimes two if theres room...easily changed if requred...

assuming you weld the angle in place then bolt the plate to the angle ? Also does it make a noticeable difference like every body suggests ?

Ive not seen many commercial units where the baffle does anything other than rest in place. Its a fairly disposable part, so a welded one would lead to future bother.

The high efficiency commercial offerings always have an insulated firebox, but that would not be easy with a round build.

Make the baffle out of thicker material than you think is required too.

I made a prototype baffle / duct on our rayburn. I made it from 2mm, which i knew was too thin, but it was only a test - i was amazed at how short a life-span it had. 1/4" is probably about right.

no just drill and bolt through the cyl, in fact you dont really need bkt,s just allow the baffles to sit on the bolt threads,....yes it makes a difference stops the heat going straight up the flue..
