I messed with this thought a few years ago.
Put a pan of hot water in the Traeger at 300 +
Had a probe in the water and let it rum to 190 ish , well above my target temp of 155 ish.
Put some VacuSucked Chickie in there.
Temp dropped immediately. as expected.
Held the pit temp up till the water recovered to 155. then lowered pit temp to 200 ish.
Water held somewhere around target temp.
Was totally not worth the effort!
