I have mine in a very large tank, and it is on most of the time, but I remove it in the summer, (It is outside in the greenhouse for my aquaculture.) It does seem to cycle off, but my use is not what it is designed for, that said, it keeps my 100+gallon tank comfortable for the fish, I also have styrofoam on the top for the plants, which adds extra insulation.

From what I've been seeing, these heaters hit the desired temp and then shut off. There's no need for the heater to work REALLY hard unless you want 89 degrees and the room temp is 65 degrees. That great of a temp disparity might lead to the heater always being on and still not reach the desired temp.

No, there is auto shutoff or pressure activation. You need to remember to shut off and unplug all on your own, which is kind of a pain. That being said though, it heats up very fast and feels great on a cold day.

I believe the instructions say that the heater will shut off if there is no water in the bowl. Mine has dried up a couple of times or been turned over by a bathing raccoon and it hasn't harmed the unit.

All I can find is that it is reflective dish heat. It has safety features that shut down the heater if it get too hot. Once cooled, it will come back on. I googled it and you can actually find the manual for it @ www.air-n-water.com Scroll down after the picture of the heater and click on the "resources" tab to view the PDF of the manual. This is my 3rd season with this heater. I live in SD we have lots of sub zero weather so I use it a lot. Still works great. Hope this helps.

The heat is automatic, but if you put cold water in it, the heater is not strong enough to heat up the water. Even if you put warm water in it, the heater only keeps the water warm for about 20 minutes and then it begins to turn cold. So I would say that you can just put the cold water in it and the heater is not strong enough to actually heat up the water.

Not sure, my heater works as instructions indicate. I would unplug it and let it sit for awhile. The button at the top takes a firm press, the heat indicator will cycle higher and higher and then all the way back to cold after many presses. Disconnecting the power for awhile should reset it to default 78 degrees. Mine is a 25 watt heater, so it will only heat a small tank that is in a room not overly cold. Good luck!

I think it means that if it were to get too hot then it would automatically shut off for safety reasons. I have this heater in my office and it would go all day long if it let it, so it doesn't shut off at any desired temp.

It has a thermostat so it will automatically come on when the temp goes below 34 and shut off above that. Mine is working well as it has been below 25 here since I got it.

Yes the heater turns off when the target temperature is reached, then the green light comes on.The red light comes on when the heater is on.Great Heater

Actually, there is no temperature control in this heater. There is timer kind of knab which shuts off the heater based on it's setting. If it is max, always heater runs. If it is low, automatically it takes lot of breaks.

It automatically shutoff water flow when temperature goes up. The annoying part is it take more than 5 minutes to cool off and resume water flow.

No there is no automatic shut off. The best you can do is set the timer so that you can turn it off when it reaches temperature. It does heat up pretty quickly though.

When you install it you also install a thermostat that has a sensor that goes under the tiles with the heater. You set the desired temperature and it will shut off when the temp is reached. I like the Honeywell with the timer so that it automatically comes on off when I want it to.

No, the heater does not turn off once the room reaches the designated temperature. I'm happy to hear your heater works. My heater stopped working.

Yes when you use the heater. When the room reaches the temp that you set the heater on it will shut off than come back on when the room starts to cool off.

Lisa I'm not quite sure what you mean by "auto off". Heaters in general, weather it be a space heater for your home, or an aquarium heater of any brand or model has a temprature control mechanism to regulate (control) the temperature to a specific degree. This particular model is I believe, when I purchased it, has a life time warranty and keeps my aquarium at a constant temperature along with 2 other heaters. To answer your question, yes it has an auto on-off when it reaches your target temperature. Hope this is helpful and feel free to ask any questions! :)
