Question 1

Anova or Wancle?

Accepted Answer

I've only used the Anova but immersion tube looks similar and the description sounds similar. For me it came down to the look and feel and I preferred the Avona. I know that the Avona indicates you need Internet access to operate but I have used it without it or at least I think I was. I've turned it on and set the temperature manually on the device.

Question 2

What does it imply that it has less power (wattage)?

Accepted Answer

The lower wattage is directly related to the smaller water bath max capacity.   The nano supports a max of 5 gallons vs 8 gallons on the 900w version.  This would be a function of both ability to circulate and ability to maintain heat in a larger bath without overusing the heating element.

In terms of cook, as long as you are operating the device within its specified range there should be zero impact.

The answers about using less heat electricity are also misleading.  I see no reason to believe that the nano is more efficient at creating heat per watt of power. Thus, for the same quantity of water both a 750 and a 900 would, for all intents and purposes, use the same power over the cook period.

Question 3

So do I have to buy a separate vacuum sealing machine to be able to use this?

Accepted Answer

The vacuum sealer will get 100% of the air out of the bag. The water immersion method of sinking the bag into the water with just 1 inch of the seal open above the water, then snap it closed, will get 99% of the air out.  I wouldn't waste money on another appliance just to get the last 1% of air out.  What I would do is invest another $20 in the stainless steel rack that keeps the bags separated and under the water.  I didn't buy the rack at first, and had generally good results.  But after reading a cookbook that warned against just letting the bag sit against the inside wall of the tank, I decided to buy a rack.  It was well worth it: putting the bag or bags in the rack allows the water to circulate completely around the bags, and produces a consistently uniform result.

Question 4

Is this new model water proof? I thought it was a major flaw that the last model's electronic display, etc, wasn't water proof.

Accepted Answer

No, it is water resistant—which is probably fine. I believe the "Frieing" is the only sous vide sick that is actually waterproof (i.e., submersible) per IPX7 standards.
