Insulated Firebox

post #1 of 8
Thread Starter 

I am thinking of replacing my fire box with a new insulated version. I guess I am one of those guys who always likes to improve or modify things. My smoker works and cooks great, so why mess with it ?  I was thinking I could make it more fuel and cook efficient. My smoker is an RF. Here is what I was thinking. inner box 20" x 20" x 20"  1/4 " plate  Outer box 22" x 22" x 22"  with 3/16" top, bottom and sides 1/4" in back and front. About an 18" x 18" cut out for door in front. Door out of 3/8"  and use 2" insulation in between

 

Not positive, just kicking it around. We are going to start on a new smoker pretty soon, may just incorporate the firebox idea into the new smoker. 

 

Anyone else made this type mod? if so please give me feed back

 

Thanks

I have never done that. What will you be using for insalation?

Happy smoken.

That sounds like it would work. The reason i as. I'm going to build a outdoor wood boiler. I haven't started researching insalation yet.

Happy smoken.

gary, do you have an upper air inlet in your firebox now...  about the height of the FB/CC opening ...    that saves on fuel and helps with temp control...

My air inlet (damper) is in my F. B. door about 1/3 to 1/2 way up. I have a 3 round hold pattern.
