Doesn't the water have to be constantly in motion for sous vide?
Water circulation is needed IF the items are tightly packed in the water---like you have 4 pint bags crammed into the water AND the heat source is just the small 2" heater in one "corner" of the pot ( the sous vide cooker). With that scenario, one portion of the water might be different temp/isolated from getting the heated water. So, water needs circulation to equalize temp.
On stovetop, with big pot with lots of water AND heat source is big diameter flame heating the whole pot relatively equally, circulation is not needed. You just dial in the temp via constant checking.
FYI, if you want to try, there is a handy and cheap small hand-operated vacuum pump and a few special bags with the vacuum hole----all for maybe $12 ?
