Review: Works great!!! - I used to use a different brand, I think it was Tetra but their heaters got bought by a different company. So I decided to go with this Eheim. Reason are is because it's just a simple heater. I didn't want a microprocessor controlled one because in my opinion, it's just more stuff that can break. The other reason was because a heater (once again in my opinion) is probably one of the (if not THE MOST) important accessory in your aquarium and should be something of good quality. I've had friends that went cheap on heater, and of course over time, they failed to the point where they were stuck in the heating position and cooked most of the things in their aquarium. Oh, and it was less on here than at the "P" stores. The Tru-Temp feature is pretty cool, so you can adjust the arrow to make the dial more accurate. I compared this heaters temp to a Fluke thermometer and it was .3F off from the factory position. Which for me is more than good enough. So yeah, I highly recommend this heater to anyone that wants a good heater. Review: Great addition - A must have for your aquarium. Works great but must clean your heater every month. ## Features - Fully submersible - Thermo safey control protects against running dry - Will automatically turn off when water level dips too low - TruTemp dial recalibrates the heater for precise temperature regulation - Made of shock resistant and shatter proof glass for fresh or marine water - On/Off indicator light for at-a-glance monitoring ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.4 out of 5 stars 1,267 Reviews | ## Images ![Jager Aquarium Thermostat Heater 100W ( Pack of 1) - Image 1](https://m.media-amazon.com/images/I/41-NtIUAmeL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great!!! *by T***H on April 24, 2014* I used to use a different brand, I think it was Tetra but their heaters got bought by a different company.

Works great but must clean your heater every month. ### ⭐⭐⭐⭐⭐ 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. ## Frequently Bought Together - EHEIM Jager Aquarium Thermostat Heater 100W ( Pack of 1) - Inkbird Freshwater Saltwater Aquarium Heater with Probe Thermostat and Thermometer Tropical Fish/Ornamental Shrimp/Reef Tanks 24 Hours Double Time with Day Night Automatic Temperature Controller - PAIZOO Fish Tank Digital Thermometer Accurate LED Display to ±0.9°F Tank Thermometer Aquarium Temperature Measurement Suitable for Fish, Axolotl, Turtle or Aquatic --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/2334394-jager-aquarium-thermostat-heater-100w-pack-of-1](https://www.desertcart.vn/products/2334394-jager-aquarium-thermostat-heater-100w-pack-of-1) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-04*
