Slow cooker was the closest category I could find.
I used my stew pot with the pasta insert. The vacuum sealer's on the fritz so I got the air out of ziplocs by submerging them, then weighted the bags down with silverware.
I used a candy thermometer for the temp. I took ds's water circulator from a fountain he got for Christmas.
Here're a couple pics of the set-up. Ignore the submersible LED lights. They are from the fountain and were better off not dangling over the stove.
What's underneath...
With the pasta insert in place...
