I think the answer is yes if you're using a large container, however, in a small container I don't think the water temp would differ from one side of the container to the other. I have only cooked for my wife and I with my DSV using a small container. I hope someone with more experience and larger cooks will help you out. Good luck and good cooking.

When I got started with the Dork product without a circulator I got reasonable results but had a problems with larger pieces of meat. As i mentioned in a past I introduced a small aquarium pump with a aerator stone that did the trick. Sounds a bit strange but got the idea from past posting. Not as effective as a true circulator but a step in the right direction. The pump and stone is very cheap and can be bought at any Walmart. Good Luck

It does not circulate the water, it only controls the temperature. I haven't noticed any reduced quality in food.

It hasn't mattered in my experience. The water temperature is the water temperature. I've made steaks and poached eggs both in a crockpot and a roaster oven, both came out just as they should. I'm having a hard time imagining what benefit a circulator would actually have. Seems to me the water movement would just cool the water down faster like it does in a hot tub. I have been very happy with this product and am considering getting a second one. I like to be able to cook and forget it for a bit.

As others stated an air pump will help, if you would like to increase the circulation from the air pump put the stone in a small piece of cpvc or other piping. Here's a pic of the general idea, just have the tube stop around the surface level of the water: http://www.koenderswindmills.com/wp-content/uploads/2013/03/air_lift_pump.jpg

Temp fluctuation when the probe is submerged is 1-2 degrees. It doesn't have anything attached to circ fluid but the response of the probe to change is quick and unless you need less than 1 degree accuracy I would recommend this gizmo.

I have experienced temperatures that were higher than the setting on the thermostat (151 F rather than 147 F). I believe this was caused by packing large pieces of turkey into a crock pot to minimize the amount of liquid. This led to lack of circulation. I plan to put something like a cooling rack into the bottom of the crock pot next time to leave space for circulation.

The water will have a natural circulation due to the warmer and cooler water moving around each other. Larger items will reduce this circulation. I use a aquarium pump with a air bubbler to help move water around. There are high temp mini water circulators available also. IMHO the water circulation is only needed when there are large items that inhibit the natural water movement but a simple bubbler will take care of that.

I have not noticed a difference as long as you keep the probe suspended in the water. Water is a poor conductor of heat and will not fluctuate very much with the change in temp of the crockpot.

We have not used the unit as much as we expected to so far.the little we have used the machine it seems to perform well.the only thing that bothers me so far is the longer it runs the warmer the food inside becomes.thats not a huge issue though if your adding ice for a smoothie or something like that. we got the referbished one to make sure we liked it first.I think that was a wise move for us.Hope this helps you out .

Unfortunately with this model you cannot make the water hotter. However, it helps to warm the cup briefly in the microwave.

No, the bowl is supposed to be self-adjusting. It kept the water from freezing, but not warm enough to produce any steam. I was pleasantly surprised at how well it worked even in temperatures well below freezing.

I have owned several of these through the years and have just worn them out but the last one I bought from Amazon did not heat either so I have not gotten another and went to the pizza cookers that rotate. The rotating ones take three times longer but at least they heat up. If I had the answer to your question I would still be using one, Sorry

It's not a cooling device, it circulates the cool air which means the thermostat does not have be set at such a low temp, which does in effect saves money. AC cost more to operate. Hopes this help. We are very pleased with ours.

I don't fully understand your question; this is a controller designed to be used in conjunction with a collector or series of collectors as well as a tank. The thermal probes included with this controller will detect the temperature of your collector in relation to the temperature of your tank, and in default mode, will then turn on your circulation pump (sold separately) when the collector is 8 degrees hotter than the tank, to cycle the heat in your collector into your tank. There are also modes you can set so that it only circulates at certain times of day, or at different temperature settings, or constantly to protect against freezing if you are not using antifreeze, or by a simple on/off switch.

No, the only thing I have noticed is if you make the water hotter or colder it does take a few seconds for it to change temperature :-)

This water heater requires a steady flow of water, it will automatically cut off it the water stops, plus if water flow is not steady the water will get hotter with less water which could result in getting burnt. You set the temp control which controls the gas and you set the water flow separately and I think it requires the water flow to be steady. If you have regular water flow this is a great water heater and I highly recommend.

The device itself is light, but the water will make it heavy, no doubt, regardless of what you use to heat it (a full tea kettle is heavy, too). This device is excellent and heats the water fast. If you have hard water just put a little bit of vinegar in it to clean it every now and then.

If you're getting 116F you are an extremely lucky individual. Mine might reach 100 on a warm day. I don't really undersand your question, but if you increase the flow of water throught the device, your effective temperature will be reduced.

Yes, the water movement definitely helps oxygenate the water, which is why I am using it. I also have bubblers because there are so many fish in a small enclosure. I like this particular model because it is more compact and I have a smaller "pond" so it takes less space and is easier to get out of the water to replace the filters. Because of algae and fish waste I have to change the filter about once a week or the fountain stops running because no water gets through the clogged filters, so make sure you get extra filters or filter material also if you want to cut your own to save money.

It does hold the temperature well, and it's easier to control the temperature than it is frying chicken in a frying pan. I suppose that's due to the built in thermostat. It has hot spots that cook faster than other areas, but you learn them quickly, and moving the food around helps remedy that.

We purchased one a while ago because my wife wanted to be able to control the volume of the flow without affecting the water temperature. It works great for that. In the fully open position it doesn't seem to restrict the flow.Hope this helps. Good quality valve.

No, you can only control temperature. Water flow is constant at one setting. It's not too hard and not too light. If I could control the flow, I would set it at what it is now.

Yes, but no worries I have had several aquarium heaters of this type. Just make sure you have a drip loop, the lowest point of the section of the power cord that is not submerged is below the electrical outlet. This allows any water that may form on the power cord to reach the lowest point of the cord and drip harmlessly to the ground (and not into the power outlet). Of course it goes without saying, never have your hand in the water when the device is on, or even plugged in. I have a little 2.5 gallon and it keeps the water just a hair on the warm side, about 79-80 degrees, but it works great and does the job.

I've used the Bissell--don't waste your money. I keep a large pan of water on the stove, once it has boiled i turn it down to keep it just under boiling. I have also heated water in the microwave. As fast as you go through a tank of water, it doesn't have time to get too cool. I know it says not to use water over 120 or 140 degrees, but I've never had a problem. The models that have actual heating elements don't keep the water as warm my methods doand they cost much, much more. As mentioned before, in order to get a real steam cleaner you are looking at several hundred dollars (conservatively speaking). I've used the Bissell--don't waste your money.
