Does this heater automatically turn off and on to adjust for the temperature in the water? (Example: Would it turn off if the water gets too warm?)

Yep! Once it reaches the temp you set it for it goes into a standby mode, it doesn't run constantly.
1780357
Yes. This heater monitors water temperature constantly. A solid light indicates the temperature you have set. A flashing light indicates fluctuations. In the case of fluctuation to a higher temperature, the unit will automatically cut off and stop heating.

Yes, there is a button on top, click it and the green light will move from temp to temp. Solid green light means it is at selected temp, blinking light means it's not. You honestly can't go wrong on this heater. Kept my rimless tank at 80* all winter (house is set to 74ish) I run the tank at 80 all the time. It only blinks after a water change. Buy this if you are looking for a sleeker heater that you don't have to mess with.

No it does not have an auto shut off or go to a warmer mode. It's 4 settings are just "off", "low", "high" and "warm".

Yes, you adjust your water temperature with the faucets and the lever turns it off and on and the temp stays the same.

Yes it automatically starts but you don't set a temperature just a range. However you will quickly equate that setting to a comfortable temperature and leave it there. The unit will come on if the room temperature falls.

Actually I did not pay attention if it automatically switch off once reached the chosen temperature, but it has thermostat. I will see in the next days if it stops or it keep on heating. I can say it is a nice and very good quality item.

It turns on and off automatically. Getting it set to exactly the right temperature may take some fiddling around with it, but once it's set it stays.

Yes, it remains off. You will have to manually turn it back on if your water cools down.

Yes the heater does turn off and back on but the temperature indicators are in increments of 5°. It shows high and low settings of 60, 65, 70, 75 and 80°

It heats the water to the desired temp. So it turns on "red light" when the degrees of the water is lower than the desired temp. If you set to 85F it will stay on until the temp of the water is 85F. However, I noticed it heats great but doesn't decide "temps" great. So I bought a Finnex Max-300 Digital Aquarium Heater Controller and the in-line heater will only turn on when my "much improved" controller tells it too. I have my controller set to 82F and my in-line set to 85F. So if the water is 81, my controller turns on power to the in-line, the water starts heating, and once the controller gets to 82F, it shuts off power to the in-line. I did this for "fault protection". I heard this in-line malfunctioned a couple of times, got stuck to 90F and never turned off. Fried all the fish in the water... Go get the Finnex Max-300 Digital Aquarium Heater Controller, you'll thank me later!

Once the water boils, it automatically switches to warm mode. In warm mode, the water continues to be just at or very close to boiling temperature. Actually you would have to switch it off if you want it to stop.

No, it only shuts off the water when it reaches a certain temp. It's not an on/off switch. You'll need to get a shower head that does that.

It turns it on and off at specific times so you are not heating water all day long unnecessarily. I turn mine in from 7am to 9 am to cover morning showers. That way it is not maintaining that hot water every time you use it. It actually stays hot enough all day anyway. If I plan to run dishwasher or washing machine, it is very easy to turn on manually for those occasions.

The temp adjustable and it stop heating at the set temp. The only potential problem I can see is the heater heating your tank to fast due to the size and that can put your fish at risk

Do you thermometer? at what temperature is your water?. Is because you have the water too hot, the heater has thermometer so it turn on when is needed.

I think the heater is thermostatically controlled and would turn off. I just purchased one but will add water as required to keep the level above the heater due to evaporation or bird drinking.

Hi Pete,Once the heating pot heats up the water it automatically shuts off and will not come back on until you manually set it.

This unit does not actually HEAT the water. It only aids in maintaining the water temperature. Hot, or at least warm, water must be put into the unit. And even then it only does an adequate job of keeping the water warm. If the unit is turned off, the water will moderate or cool quickly.
