One question about the product - it doesn't look like it's actually circulating the water. The specifications are a bit light ("Water Baths: 1" counts as a specification?!), but I see nothing about it having a pump. Is this just a really expensive (and accurate to within 1 degree) crock pot?

That might help reduce hot spots, but a strong current will get in between items and around the edges of bags that might obstruct a mild current caused by heat natural convection. Also, (and this is where I'm calling on physics intuition and should probably channel McGee) an actual pump-driven current will act like a convection oven which does more than just equalize temperatures within the physical space.Khaopaat wrote:It sounds like you're right - if the Serious Eats article is accurate, it doesn't have a pump. It sounds like it has either multiple heating elements spaced in a grid under the bottom of the water container, or one heating element that can be heated in zones. Either way, they claim to create a convection current by turning specific heating elements (or zones of the heating element) on & off at specific times.
I have a Neslab EX-111. It looks basically like this:Khaopaat wrote:On a side note, what kind of circulator do you have? Do you get a fair amount of use out of it?
The issue of convection (addressed in my recent post upthread) aside, I often place multiple bags of things straight from the fridge directly in to the water - I have a hard time imagining that the "uniform temperature" this thing creates without circulation is going to get in between two bags. I'm also curious how quickly this thing recovers from having cold items plunged in to it.spinynorman99 wrote:Immersion circulators heat at a single point so they need to circulate water to maintain temp (water at far side of container would be cooler than water at the heating element so you'd lose the precision that sous vide requires). This device creates a uniform temp so circulation is not necessary to maintain a uniform temp.

Here is another website with sous vide supplies and machinery.

They say it's a $75 Immersion Circulator, it's coming out closer to $100 once you factor in shipping.

Yup, that looks to be pretty much identical.
I will end up with a few spare parts when I'm done (including an extra circulating pump and a source for a few more), give me a holler if you're going to try this.
