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.
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.
Sir it says also that the jager has"With automatic dry run shut-off (Thermo Safety Control)" feature so did it realy exploded or the glass breaked on your jagers after exposure to air
@@AquaSplendor I searched for videos on testing the jager on situations of sudden aquarium leaks to fully drain of the tank water if the product lives up to its promise but sadly I found none
@@AquaSplendor no sweat sir just do it when you have free time to spare. A lot of us hobbiest here do settle for another brand like periha who has a plastic guard but some of us here do settle for durability of OG brands in the fish keeping hobby like my precision top filter who had been around for 8 yrs still working fine
@@AquaSplendor hey i did sent 2 emails they just said it was dependent on room temperature which on one hand i asumed yes if the tank is in outdide garage not sure if anyone would do this but in winter my hwating is on so in tbe end i gave up. 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
I got the thermo e 125.. In a 135litre tank right next to flow from filter.....how often does the red/ green light change for you, mine is roughly green 2 - 5 mins then red 1 - 3 mins is this right ???
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!
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.
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.
You think they will get ride off the Jager? I don't know, its popular because of the "cheap" price. I'm thinking to replace ALL my "not so old jager" with thermocontrol to prevent any accident
@@AquaSplendor greece. Both were working fine for some months. After I removed them from water and let them for several weeks in the box due to summer season they never worked again. Green light was not on anymore after connect them.
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!
@@AquaSplendor sadly around 30% of all heaters have condensation inside, so its considered "normal" from the manufacturers. They work just fine for decades, its just annoying.
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.
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
Mas é o jager cabeça azul? Ou o novo o thermcontrol-E cabeça vermelha ? E que este último não vale um piço, tive dois , o primeiro morreu do nada passado dois anos o segundo dado pela garantia morreu da mesma maneira passado 11meses.
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).
@@AquaSplendor Okay, disassembled is maybe not the right word to use? I have destroyed the jager heater to look inside. Okay, I thought you may not know this old glow lamp which also used in old light switches, my young padawan :-) The new one have Led of course.
@@abyankabir1910 Yeah that 3 year warranty on Eheim is what give me more confidence, they trust their product to last a "normal life". It feel weird to replace when something just.. work

Any luck with the thermocontrol e?
mine failed after 4 years.overheating the water.
These are really good heaters! Super reliable and maintains a very tight temperature range. A+
Sir it says also that the jager has"With automatic dry run shut-off (Thermo Safety Control)" feature so did it realy exploded or the glass breaked on your jagers after exposure to air
Exposure to air. I read that too for the jager but in my experience it doesn't work with air, I don't know if they meant inside water only.
@@AquaSplendor I searched for videos on testing the jager on situations of sudden aquarium leaks to fully drain of the tank water if the product lives up to its promise but sadly I found none
Maybe you could make a video on testing it sir will share it to friends and groups for the views do you still have jager heaters sir

Both have a dry run protection not only the new model
my new eheim thermocontrol heater doesn't work; the value of the ohmic resistance is infinite, ie the electrical circuit is embodied.
Hi it’s normal for the E the red lights never turn off always on please help.thank you
After exceeding the temperature set? no
i have the eheim thermocontrol 150 watts in my 25 gallon (100 L ) i Set it to 28 c it only reads 20 c
can anyone help ? what should i do ?
Talk to the company with their support service
i have a problem with mine too have tried to calibrate mine is set to 30 can only get to 28 i have one 300w and one 200w in 365 litres of water

Dont Jager heaters also have the dry run protection?
Ask the thousand unit pop/crack when running dry and keep heating.
@@AquaSplendor That does not answer the question, both the Jagers and thermocontrols advertise the same dry run protection

The thermo has a design flaw . When you twist the top it loosens the seal and allows water to enter
After how long time did this occured?
@@steffeo withing the warranty period . Basically it is a design flaw . Take a good look at the top portion .
The jeagar is the way to go
Looks like Eheim made nothing but good improvements. I'll pay for the new model.
Hi!
The only difference between them is only the calibration and the light indicator?
(I'm sorry I don't know your language.)
And it won't crack when left outside
@@AquaSplendor So is there a risk of cracking in the model named jager in this way?
@@kp4092 yes
