WSM 22.5, How long should a full load fuel last

[KKamps]

Hi All
How long should a full load of fuel last on the WSM 22.5" running between 235-250?

Thanks

I've gotten 24 hrs on a 20 lbs bag of kbb. It was in the summer though.

Mt first load lasted about 9 1/2 - 10 hours. So I'm not far off the mark, I've seen some videos on you tube and they say they can easily get 18 hrs out of a full load on a 18" WSM.

I just ran my 22.5"wsm this weekend for almost 18hrs and only ever add half a chimney of lit near the end to up my heat to 300°. I ran a bunch of lump that i started with half a chimney of lit kingsford, w/o water and foiled pan.

18 hrs on 22" on full load is usually what I get. Food is done by then anyway. I run it with a pitmaster iq110 though. I tend to believe the temp controllers consume a little more fuel than when left alone.

I just got 17.5 hours at a steady 250 today on a 18 lb. bag of Kingsford Blue. At 19 hours its sitting on 200.

I got around 12 hours with full bag of kingsford over memorial day weekend.

Using charcoal at 250F max 15 hours. Much better with briquettes (up to 20 h)
