Ok Ive been losing a lot of heat out my exhaust stack .Ive been thinking about adding another tank to the top to help catch some of the heat . My old wood bruner had one on top and it helped a lot .My exhaust stack is around 400 degs . Ive been thinking about maybe a 15-25 gal tank . I saw a air tank off of a large truck that looks like it may be what I'm looking for . Any one tried this yet ?

more surface area more heat. remember these heaters use draft so too much may remove too much heat from the stac thus reducing draft. i would double the size of the tan you are using now. most of the 55 gal drum heaters use 2 drums. thin about a clean out for the upper one.

I'm going to try a small tank and maybe a fan to blow across the top tank . I'm still going to see if I can think of something else to try first .I've may even try puttting a small tank standing straight up on the end and using it has part of my exhaust stack . I've got about one more month of cold weather to use it and after that i can start taking it a part . I can start trying diffrent things with it .

my heater has steel pipe running through it . i can tae enough heat out of the stove that the draft stops. with the set up you are gonna use i dont thin you could pull enough heat off it to stop the draft. my stac temps range around 150 degrees f unless i over do it on the fan and slowly the draft stops and smoes out the shop

my shop stove is a barrel style on the bottom and when the top barrel rusted out i used a fuel oil tank 225 gallon on end. looks terrible but wow the heat.
