## Questions & Answers

**Q: I have had these go bad on me didn't get more than 2 years out of them Can anyone recommend a better brand?**
A: I change mine every two years. You take a glass and rubber device, submerge it,  watch it heat and cool many times per day and expect it to live forever. Won't happen.

**Q: Does this fit in a 10gal tank?**
A: It will fit, but it's too much heater for a ten gal.

**Q: Is EHEIM Jager Aquarium Thermostat Heater 100W fully submersible in  water?**
A: It is completely submersible. If it isn't submerged, the automatic shutoff may kick in. It will work vertically or horizontally. I installed all of mine horizontally behind the rocks so they aren't visible.

**Q: Is this good for a nano tank?**
A: This is good for a 20-30 gallon tank. Most nano tanks are much smaller and stand the chance of overheating. Even if that didn't happen they would cycle a lot and wear out quicker. Also, they are pretty long and most likely would not fit in a nano tank.

### ⭐⭐⭐⭐⭐ Great addition
*by D***V on January 4, 2026*

### ⭐⭐⭐⭐⭐ Heater

The quality I expect from Eheim. Great heater! Thank you

### ⭐⭐⭐⭐⭐ It’s not pretty but it does a good job
*by Y***N on September 22, 2024*

I’ve been using cheap tetra heaters for a while but had to retire them, so figured I’d try Eheim. It’s ugly and I can see it shining through from behind the plants (it’s pretty thick foliage too), but right out of the box the temperature was spot on. It does fluctuate a bit at night and at the warmest part of the day, but it’s only by 0.2 to 0.4 degrees so I’m cool with that. Just know it’s gigantic and very shiny so it’s not for aesthetics. It’s a beast of a heater, more than twice the size of a 100W tetra heater. I will update this review when I have to replace it.
