getting ready to order a reverse flow smoker from Shirley Fabrication and they offer a upgrade on a insulated fire box and it is kinda pricey . does a insulated fire box really help that much ? the steel is 3/8 inch thick and would like your guys opinion , thanks .

First off let me say that you could not have chosen a better fabricator to build your cooker. Paul and Tyler are Top Notch Fabricators that build cookers that work.
For every person that says no it does not help that much there are just as many that will say yes it does.
My opinion is if you are going to insulate the firebox you should be looking at insulating the cooking chamber as well because your heat loss there matters more in my opinion.
Believe me if they were so much more efficient Bahama Mama would be sporting one, in fact cooker for cooker size wise I burn about 5 splits more than one with an insulated firebox.
I hope this helps. Very Happy

i was kinda thinking not getting it because it a $600 upgrade but thought maybe lining the bottom and sides of the fire box with fire bricks would be good enough . just me thinking but heat rises and as long as you got a good draft pulling air though the smoker it would be okay with out . thanks for you imput .

Neth,

I insulated the firebox on my offset mainly because I knew there would be little kids around when I was smoking and wanted to be able to touch it with an instantaneous burn happening. To that end I succeeded, however, I'm still throwing sticks in her every 45 minutes to an hour, which I would bet k.a.m. is also doing. So, is say you aren't going to gain much that way from insulating, but I do think that with my design and the insulation recovery time from opening the door is minimal. Others with non-insulated fire boxes may also feel that temp recovery is a non issue as well though.....

I'd say that I don't think I'd spend $600 for that option.....

Good choice for a pit. You will be very happy with it!

Ed

Depends on a couple of things IMO, where you cook, (temporal zone), and availability of cheap wood.

Up here in Utah with colder weather and lack of "cheap" available wood, it can be worth the extra cost on the front end, to help reduce the cost on the back end.

Insulated fire boxes don't cool down as much uninsulated ones when it rains, and while the size of the cooking chamber affects the flow of the smoke more, the draw is IMO more important to the cooking, than the temperature of the chamber. With the firebox it is the reverse, if your firebox gets cold and wet, more heat from the efficient burn in the firebox, appears stay in the firebox keeping it warm, and cooking temperatures drop accordingly.

So like all things, you pays your money and you takes your choice, I would consider it a worthwhile investment on a cooker I was going to use up here, maybe wouldn't if it was not as cold, wet, windy, and cheap wood was readily available.

A cord of Hickory out here is about $400 if you can get it.

Apple, Peach, Apricot somewhere between $280 and $320.

I also just noticed they have a 1/2" fire box option and that would save me $250 and I would think that thick of steel would be better than a insulated one . any thoughts good or bad idea ?

My thought is on a long cook once the firebox has reached its heated temperature the value of thicker metal is reduced because you are expelling your radiant heat. If you want to retain the heat efficiently then an insulated firebox is the correct option.
I hope this helps. Very Happy
