With the EHEIM ThermoControl electronic heater series, your aquatic environment maintains the perfect temperature with exceptional precision and reliability. Designed to be simply hung in the water, these ultra-modern heating devices combine proven principles with advanced technology to ensure stable and accurate temperature control for aquariums ranging from small to very large volumes.
The heater features precise temperature adjustment from 20 to 32 °C, with an outstanding control accuracy of ± 0.5 °C, eliminating the need for readjustments. Intelligent electronics continuously measure and maintain the set temperature, providing consistent warmth that your fish and aquatic life can depend on. A clear control lamp signals the heating status—red when warming up and green once the desired temperature is reached.
Constructed with a special laboratory glass coating, the heater’s surface area is increased to optimize heat emission while serving as a heat shield for even distribution. This robust design is fully submersible and waterproof, ensuring safe operation in both freshwater and marine aquariums. Equipped with dry-running protection (Thermo Safety Control), it prevents damage in case of water level changes, enhancing safety and durability.
Each heater comes with a convenient 170 cm cable and a double suction holder for easy and secure installation. Available in multiple sizes, they accommodate aquariums from about 20 up to 1200 litres, making it easy to find the perfect fit for your setup. Manufactured in Germany, these heaters combine highest safety standards and reliability, backed by a 3-year warranty for your peace of mind.
Experience the perfect balance of simplicity and innovation with a heater that delivers consistent, precise temperature control to support a healthy and thriving aquatic environment. Whether for freshwater or saltwater tanks, this heating solution ensures your aquatic pets enjoy optimal comfort all year round.
