Eheim Jager 50w Heater

The Eheim Jager 50W heater delivers precise temperature control for aquariums between 25–60 litres, maintaining settings from 18°C to 34°C with laboratory-grade accuracy. Its borosilicate glass jacket maximises heating surface area, allowing efficient warmth distribution with less wattage than comparable models. Fully submersible and dry-run protected, it suits both freshwater and saltwater systems. The safety glass resists chemical and biological degradation, thermal shock, and condensation penetration—ideal for reliable long-term performance. Note: heating capacity assumes ambient room temperature fluctuates within 5°C of your target setting; larger fluctuations may require higher wattage.
