Question 1

Why has it stopped circulating water and water temperature goes up and down with a range of 10 to 12 degrees?

Accepted Answer

Because it's broken.

Question 2

Can you cook without app ? Without WiFi ?

Accepted Answer

We have not used the app and have cooked many things. We really forgot or didn't realize there was an app. I knew there was an app that showed recipes, maybe that is the one. But, yes cook app and WiFi free.

Question 3

Is there a maximum size larger than 50 liters for a covered insulated cooler setup with this 1000 watt sous vide cooker?

Accepted Answer

The limit is determined by initial water temperature, food mass, and thermal losses.  If you are asking because you want to cook a larger volume of food than will fit into a 50 liter insulated container, then you should probably be looking for a commercial unit with a larger heater (maybe 3 to 5KW).  If you are interested because you happen to have a larger insulated cooler and want to use it to cook at modest temperatures (below 160°F), then I would run a thermal test on your cooler by filling it with 160°F water, instrumenting it with a type K thermocouple (or a few) and watch how fast the water temperature drops with no added heat.  A 1KW sous vide cooker will supply 3413 BTU/hr and 50 liters of water is approximately 53 lb and thus a 1°F temperature drop is a 53 BTU thermal loss and if the temperature drops by more than 30-35°F in the first hour, then you have too much loss to actually cook in that container since you need 500W to do the cooking while the rest of the power goes to makeup for losses.  You can scale this to whatever size container you want to test so long as you leave 500W available to heat the food after offsetting the conductive and convective losses.

Question 4

What is the max temp; will it cook at 203 F?

Accepted Answer

Max temp is 197.  203 is getting very close to boiling, so there's likely an issue with keeping water that hot without heating the element to a level that would cause flash steam inside the cooker.
