The Eheim Ebo Jager is Eheim’s classic adjustable glass aquarium heater. Eheim now calls this line thermocontrol (without the “e”). You set the temperature with a dial on the heater. It is a different product from our electronic Eheim ThermoControl e heaters, which have a digital temperature display and cost more.
Choose from eight sizes, 25W to 300W, for aquariums from about 5 to 264 gallons (20 to 1,000 liters). The heater is fully submersible, uses a laboratory-glass jacket for even heat, and has dry-run shut-off plus a control lamp. Eheim rates it for freshwater and saltwater. Ships via UPS.
Features
- Dial-set temperature: precise adjustment from 64–93°F (18–34°C), with simple recalibration (±2°C).
- Steady control: holds temperature to ±0.9°F (±0.5°C) and keeps heat at a constant level.
- Control lamp: a light shows when the heater is actively warming the water.
- Fully submersible: watertight and designed to hang in the aquarium.
- Thermo Safety Control: automatic dry-run shut-off if the heater is not in water.
- Laboratory-glass jacket: increases the heating surface, acts as a heat shield, and helps emit heat evenly.
- Cable and mount: about 67 in (170 cm) of cable, plus a double suction cup holder.
- Freshwater or saltwater: Eheim rates this heater for both.

Specs from Eheim’s thermocontrol (Jager) documentation. Gallon ranges are conversions of Eheim’s liter ratings and are heater capacity, not tank freight sizes. Eheim also makes a 125W size (40–53 gal / 150–200 L) that we do not currently stock; for tanks in that range, choose the 150W or contact us. Eheim may update parts and ratings between production runs.

Warranty
The Eheim Jager / thermocontrol heater is covered by Eheim’s manufacturer warranty only. Please see the Eheim packaging and manual for terms. TRUVU does not provide a separate warranty on Eheim products.
FAQ
Is this the same as the Eheim ThermoControl e heater?
No. This is Eheim’s adjustable glass heater with a dial, which Eheim now labels thermocontrol. The ThermoControl e is a separate electronic heater with a digital display. You can carry either one; the Jager is the more affordable option.
Which wattage do I need?
Use Eheim’s capacity ranges in the chart above. If your aquarium sits between two sizes, or in the 40–53 gallon gap where Eheim’s 125W would normally apply, choose the next size up or contact us before you order. Browse our aquarium heaters.
Can I use it in a saltwater tank?
Yes. Eheim rates the Jager / thermocontrol heater for both freshwater and marine aquariums. Shop our freshwater acrylic fish tanks and saltwater aquariums.
What warranty does it have?
It is covered by Eheim’s manufacturer warranty. See the Eheim packaging and manual for details. TRUVU does not provide a separate warranty on Eheim products.
