If you want to see my review for the thermocontrol-e: kzread.info/dash/bejne/nJZ_pdxmgazec5s.html

These are really good heaters! Super reliable and maintains a very tight temperature range. A+

At the beginning of my hobby I used the stock Juwel heater in the filter. Almost every year I needed to buy a new one because of many issues: broken cable, always on heating, no heating... When I bought a Jäger from Eheim and placed it freely in the tank, all my issues disappeared. Now I have it at least 8 years still going strong :D The only issue I have is water condensation inside the heater, but is understandable after so much time.

8 Years! wow that is impressive

Thank you! Wish I had bought the thermo one!!

I've use Jager heaters for over 26 years without a single failure except receiving one dead out of the box. My next purchase will be the Thermocontrol-E. I like all the new features.

Same here, I never had any issue with them. I broke I think 2 in more than a decades, but it was because it was out of the water, so that feature already been useful for me :P. I'm thinking to replace ALL my aquarium heater with this one.

Any luck with the thermocontrol e?

Hi! Thank you so much for making the review! I ended up getting the Thermocontrol. I have a question that's been concerning me. When I was doing water changes, I accidentally left the water below the "minimum waterlevel" line for a few hours, but the glass tube was still fully submerged. Is this ok? Only 1/4th of an inch was exposed to the air, so I'm not sure if that was enough to trigger dry-running protection. Should my heater still be fine? I'm worried of any potential problems like residue or cracks. Thank you for your time!

Hello, Please advise if the light on my Eheim Jager 3617 should stay on all the time indicating the heater is working good? Thanks.

And watched this one as well! Thank you. I have one question: Does the Thermocontrol E get moisture inside over time? I have a Jager which has some moisture visible inside the heater, this has happened to a lot of my heaters, so much so that I consider it quite normal but it would be great if the new E model doesn't get this issue, thanks!

my new eheim thermocontrol heater doesn't work; the value of the ohmic resistance is infinite, ie the electrical circuit is embodied.

I'm sure the price differences are because it is the old out dated one vs the new and improved. I'm sure they are going to phase out the Jager. and go to the Thermocontrol. I still have some of the old green Ehiem Jagers and they still work great.

People love simple things that work. I highly doubt it will go. The newer stuff comes with some many issues

The best hack for these heaters. Is to buy aqua one heater suction cups clips. All aquarium stores sell them as spare parts. They grip the heater better and the suction cups last a lot longer.

Ive just got a 6ft tank and ordered another 300w so it should heat up 2000 litres so being 600 litres should be ok I will soon find out Thanks for your reply

Looks like Eheim made nothing but good improvements. I'll pay for the new model.

O meu tem 8 anos sempre a trabalhar raramente desliga .mas tem a temperatura sempre boa da água do aquário

Le nouveaux model termocontrol-e. Je crois que la grosse difference c que le (e) c pour electronique. Donc serais suposer garder une temperature plus stable et faire attention de respecter les specification du fabriquant poir le nombre de wattage vs le nombre de litre. Les eheim sont plus performant que les autre marque

The jeagar is the way to go

Great comparison! However bad tip on buying the higher watt heater of the same price. You want the appropriate watt heater for your tank, which is why they make different wattages! Oversized wattage can heat up your tank faster and cook your aquarium. In instances of heater malfunction, correct sizing have less chance of doing so because it takes longer to add heat-ideally one should get the lowest watt needed to heat the tank to desire temp. Moreover, appropriate watt heaters will last longer because it is not constantly turning on and off!-reason for heater failure according to Corey from aquarium coop.

Hi! The only difference between them is only the calibration and the light indicator? (I'm sorry I don't know your language.)

I already disassembled a broken heater. The rough turn of the temperature is caused by the very long sealing gasket. The wheel even get more rough if the softener gone. The light in the old heater is not a LED, it is a glow lamp which get the full supply voltage ( In Germany 230 Volt).
