Im wanting to use a heater in the water for two different temperatures at different times: 85 degrees & 110 degrees. Is it possible to regulate temp?

I don't see why not, but I used this model for a jacuzzi heater, so it did it's thing at the higher end of the range. You would need an external regulator I believe, as this one has an internal device that can't be accesssed or set.

No - It does not have an adjustable regulator. It is a sealed unit. Mine broke after two months of regular, but not continuous use. I would not buy it again.
1001603
No. if you use a separate controller, which I do, then it can be easily adjusted to the temperature you want. I use the Ranco ETC-111000-000 Prewired Digital Temperature Controller (ETC-111000-000W) from ETC Supply.. They can also supply an extra length sensor wire and also install heat shrink tubing for underwater use. As far as a automatic timer for the different temperatures, I don't know about that.

no temperature controls on unit, you have to do that manually with your own separate thermometer and removing heater at desired temps. Having said that, this heater worked perfectly fine for what I needed it for.

No, it cuts on when temp is below 80 and cuts off above 110. To regulate and keep my talipia tank ~85, I float 5 gallon buckets with the heaters in them within the 300 gallon tank, lowering the heater buckets into the tank when temps are due to drop below freezing.

These 5 answers are only half correct ,you can use thermostate . THey can be wired to turn on and off with heater set to a certain temp.

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.

I replaced this with one that had the actual temperatures. My guess is that A would be 120 degrees - B would be 140 degrees & C - would be 160 degrees. Since I replaced this I tried temps below the A mark 120 degrees & I am currently running just a little higher then the A mark which would probably be about 125 degrees. When setting the Temps I believe you should also match the upper limit switch setting to your lower limit switch . My tank is a 40 gallon tank & like most electric hot water tanks there are 2 thermostats. Upper & Lower.Hope this answerers your Question! Ron

yes, after awhile, the sensor in the temp probe goes bad. It reads the water temperature at lower than it really is and thus the heater overheats. You can adjust downward the temperature to compensate, BUT THE SETTING RESETS TO 79 F EVERY TIME THERE IS A POWER FAILURE so you could end up overheating your tank anyway. Avoid. Right now, 79F setting for me = 89F actual water temperature!

The heater has a setting for pools that goes up to 90° I believe. It also has a setting for spas I'm not sure How high it goes because I only use the heater for my pool. I don't believe you could separate the two functions out and heat both the pool and spa at the same time.

110.. Mine worked for 6 years and then died BUT IT DIDN"T overheat.. It just wouldn't keep the aquarium warm anymore.. None of my fish died and if you are checking it daily it shouldn't be an issue.. I believe these are great heaters! I now have another that is 1 and a half years old

The output temperature is dependent on three things. 1)Input temperature 2)Gas Knob (Burner Setting) 3)Temp Knob (Water Flow) The output temperature but can be lowered quite a bit. Unless your source water is already quite warm I would not expect any issues keeping it below the 85F output. However since the input temperature is what determines the min and max it ultimately depends on your cold water input temp.

The upper and lower thermostats should be set at the same temperature. If you have anyone disabled, small children, or elderly, it isn't recommended that you set the temperature past 120. If you are running out of hot water, or the water has a bad odor, turning the temperature up may help. As a plumber, I recommend setting the tank to 120 and see if you have sufficient hot water. If you do, leave it alone; lower settings are beneficial for numerous reasons. 140 degrees will kill all bacteria that may be in the water, but at an increased risk of scalding.

Possibly so I have a 300 watt and I have to turn the temperature down below what is recommended for my Oscar's in a125 gallon tank Or there could be something wrong with your heater :-)

Sure can. Works perfectly. Dono about consistently I only use when water drops below 66 degrees. My 55 gallons in sun room summer now ..will probly b using full time in winter. Dont listen to box directjons. All tanks settings. Environments and treatmsnt are different for all tanks. Know your tank and lighting situation. Before u start talking crap on heaters. Research then buy. Recommended for sure.

No, probably not in the sense you mean. This is an eight watt "always on" type of heater, it has no thermostat. The heater will continue to emit eight watts worth of heat whenever it is plugged in. With very few exceptions all small "bowl" or "betta" heaters work this way, the only difference is the wattage. They are available in 5 to 15 watts, you need to match tank size, ambient temperature, and other variables to heater wattage. A thermometer and monitoring is essential, especially at first to determine what temperature a particular heater keeps a particular tank, and if room temperature rises so will the water temperature. The term "preset" is not really applicable to these heaters, preset heaters have a thermostat that is permanently set at a certain temperature. If a heater description uses the term preset without stating a specific temperature (usually 78) then it is NOT a thermostatic heater- it is an always on type. In too small of a tank or too warm a room these can overheat the water. Bettas are very heat tolerant, which is why using these heaters is feasible, but care is still needed. In anything under 3 gallons I think eight watts may be more than needed unless in a fairly cool room.

No, it should be fine. These heaters have an adjustable settings. I have a 300 watt for my 90 gallon fish pond and have it set at 80 degrees. It kept the water warm and prevented it from freezing during the winter.

I have a 46 gallon cichlid tank and I bought a 300 watt heater. With the adjustable temperature control, I am able to keep it at a steady 78.4 degrees.

Switching the heaters from tank to tank should be easy enough. Making sure there are no sudden temperature changes is the hard part. With two heaters in two identical tanks in the same room this might work, but only if the two heaters have exactly the same setting. This might not be true. Just a degree or two difference is enough to stress a fish (says some web pages). You should check that the two tanks are at the same temp with a really good thermometer. I have just one 2.5 gal tank and change about 10% of the water daily by drawing off a quart (with a turkey baster) then warming a quart jar of new conditioned water by putting the jar in the tank for half an hour or so.

It just has dials for water flow and gas flow. Not for specific temps. Your incoming water temp is another variable. If your water must be a very specific temp this may not be the right water heater for your application.

You can't regulate the temp. You should strategically place it in consideration with the other heat sources in the tank so that your reptile has temp variety within the tank. I use 3 thermometers in the tank to keep an eye on the temp. Hope this helps
