The Aquael Flow Heater is the first flow heater for the aquarium with Smart Heating System (SHS), a technology for intelligent power selection. The microprocessor adjusts the heating power to maintain the correct temperature in the aquarium. This solution enables smooth operation of the aquarium heater without temperature jumps in the aquarium and without stress for the aquarium inhabitants. Thanks to the electronic thermostat, the LED display shows not only the programmed but also the current water temperature. Electronic temperature sensors protect the aquarium from overheating, and if they detect a failure of the water flow, they automatically switch off the unit. Attaching the aquarium heater to the outlet hose of the external filter allows the heated water to be evenly distribution of the heated water throughout the aquarium. The aquarium heater is mounted outside the aquarium, so it does not take up space inside and offers more freedom in design.
