Aquael Flow In-Line Aquarium Heater

Experience advanced aquarium temperature control with this intelligent flow heater featuring a Smart Heating System (SHS) – an innovative power adjustment technology. The integrated microprocessor dynamically modulates heating power to maintain the desired water temperature, ensuring smooth operation without temperature surges that could stress aquarium inhabitants.

Equipped with an electronic, high-precision thermostat, the LED display conveniently shows both the programmed and current water temperatures, allowing for easy monitoring and adjustment via a single button using the One Touch System. The temperature regulation range spans from 20 to 33°C with an accuracy of ± 0.5°C, providing reliable and consistent heating performance.

Safety is paramount with three temperature sensors—two electronic sensors and one thermal fuse—that protect against overheating. Additionally, the heater automatically switches off under no flow conditions, preventing dry operation and enhancing durability.

Designed for installation on 16 / 22 mm diameter hoses connected to external filters, this heater ensures even distribution of warmed water throughout the aquarium. Its external mounting frees up valuable space inside the tank, offering greater flexibility in aquarium interior arrangement and maintenance.
