Eheim Jäger - Complicated or I am at fault? Probably that latter :)

[Faccia di Pesce]

I hate these heaters. For the life of me I cannot calibrate or figure it out and cannot get my temp to the parameters I want. Returning them and buying a InkBird with two simple heaters.

Any suggestions on two heaters for a 40Gallon Breeder with a approx 30 gallon sump?

I want to keep the heaters in my sump (one in skimmer section and one in refugium section) my return is in the middle.

Ignore the calibration ring and printed numbers. Dial in the temp with an external thermometer or the inkbird and you are good to go

True story! I have Eheims and I had to set mine to 68 to keep my DT at 75.5. Don’t trust the ring! Lol Good luck

Its disappointing Eheim doesnt address this, but for a relatively inexpensive heater that is built like a tank and super stable once dialed in I can overlook it. Just a bit of a barrier to those new to the product.

Yeah I’ve tried on my freshwater tanks to dial in using the calibration where you move the ring etc but I never had much luck. I had a digital infrared thermometer that I use to check when to heaters turn on/off and I will just turn the knob down/up until it’s where I want it.

Example when I first put my 75w into my reef tank it was set for 79 but was heating to 82 and would kick on at 81. I just turned it to 75 and now I’m constantly 77-78.

Same experience here with eheims. Currently have my ring set on 75 and it runs at a constant 78. If you’re not interested in a separate controller, it’s a good heater once you get it calibrated IMO.

I honestly wish heater manufacturers would spend r&d efforts on building a high quality heater model that runs at a constant 78–no ability (or need) to adjust. The vast majority of all reefers would be very happy with a steady 78.

I use aqueon preset heaters for QT tanks. Love those things.

Honestly I have never had an issue with the ring... After the heater reaches steady state, unplug and adjust the ring and plug it back in. I think a majority of the issue is that the heater output and tank being used to calibate it need to be in the middle of the range. Other heaters, large pumps and lights need to be cut off which is kinda silly. Get an inkbird or controller cause its too much of a hastle.

 

[New&no clue]

I watch a video from BRS on how to calibrate mine, but could never get the ring to match. Finally I just gave up on the numbers and tweaked it over the next couple days until the temp in my DT was were I wanted it.

My red rings can never seem to turn far enough where I need them.

 

[Faccia di Pesce]

I left the heater in a bucket for 2 hours. The temperature in the water is either 82 or 83.5 according to the thermometers. But the heater is set at 79.

What am I doing wrong here?

 

[Cell]

Meh.

Move the red ring to 82. Then adjust the blue dial to where you want it.

thank you.

Could be an issue with circulation in the bucket too.

Most heaters will not heat a bucket of water evenly without circulation.

i put a pump in. Still trying to figure it out. At end of day if I can't get it to work going to return and get Cobalt heaters. Just ordered the Inkbird controller as well.

thanks

Cobalt heaters have a pretty bad reputation for eventually exploding and fouling the tank. I actually just switched away from cobalt.

I am now using the BRS titanium heaters with my Neptune for control.

thanks for the insight. will check that out.
