Ive been using these heaters. 2 of the 4 i have had stopped heating but the light is on. Feeling the tube its the same temp as tank water. I wonder whats up with this? Dry protection shut off? Any way to reset it?

I would suspect that the heating element has failed open. Voltage is making it to the light which I wouldn't expect if there were some shutoff applied.
I was told they stop heating well after a while due to corrosion on the heating element. I had two I pulled out of storage after 5 years, one was used less than a year. Neither would heat water much higher than room temperature.

The other part is that once a heater proves it's not reliable, replace it. The only exception I could see to that would be if the local controller failed and you have an additional controller - but even then. Jagers are $30. Good heater as any and better than most.

Ive had bad luck with eheim Heaters, but customer service was wonderful.
Story: one of my 200w heaters would constantly cycle on and off according to my apex power readings, reguardless of how high i set the manual tempature on the heater itself. I sent a screenshot to eheim and they offered to send me a new one for free. Even upgraded me to a 300w for free when i asked.
Unfortunately the 300w only ever draws 150w so i assume one of the two heating elements internally is bad! All well. At least the experience with customer service was easy!
Good luck

If you saved receipt or have some proof of purchase...you should be able to talk to Eheim. Unusual to have 2 of those go like that.

No didnt save receipts unfortunately. I expected they would last a year.
I wonder if the dry run shut off is thermally activated or has a water level sensor? Becaise the top 2 inches is above water. And they dont get much flow where they are.

Hmm. Good thought. Can you spread them out to different locations? Maybe that way the heat wont build up and trip each other? Or even turn one off and leave the other running. See if it will work then. At least worth testing out

I've had two of these heaters fail over the last decade. In both cases there was an observable break in the heating element wire, presumably from corrosion. One was under warranty and got replaced, the other was older.
They have dry shut off? There is a minimum waterline sticker on mine, and it's just over halfway down from the blue ring.

Did that work?

No it still doesnt heat. I noticed a little streamer of condensation coming in from the cap though. Nothing huge but enough to probably short circuit the heater. Garbage it goes.

I was afraid of that. These were my first heaters and I was pretty sure that the light goes out if the run dry sensor is triggered.
Aquarium heaters shouldn't be this hard, but I am excited about the new line of BRS branded heaters. They are made by a very high quality European company. They will definitely be the next heaters I order.

Yup. You need a controller (I use a Profilux) which I recommend using anyway for safety reasons. To my knowledge these are considered the highest quality aquarium heaters in Europe. BRS is having them rebranded with 120V plugs for sale in the US. Otherwise, they aren't available in the US.
Do a search for Schego aquarium heaters and read the reviews from Europe.
