Aquael Flow In-line Aquarium Heaters

Heat your aquarium without cluttering the tank with the Aquael Flow 2.0 In-line Aquarium Heater, available in 300W and 500W versions suitable for aquariums up to 1000 litres. The Aquael Flow Heaters keep your aquarium comfortably heated without adding equipment inside the tank. Mounted on the outlet hose of an external filter, this in-line aquarium heater helps distribute heated water evenly throughout the aquarium, leaving more space for fish, plants and aquascaping.

Aquael Flow In-line Aquarium Heater Key Benefits:

• Even Heat Distribution: Positioned on the outlet hose of an external filter, the Aquael Flow Heaters warm returning water to help distribute heat evenly throughout the tank.
• Less Aquarium Clutter: External mounting keeps the heater out of sight and out of mind, freeing up space in the aquarium, providing greater freedom to arrange plants, décor and hardscape.
• Intelligent Heating: The Aquael Smart Heating System (SHS) adjusts heating power to suit the aquarium’s size and conditions, helping maintain a stable temperature while using only the energy needed.
• Easy Temperature Control: The LED display shows the set and current water temperatures, while One Touch control lets you adjust the setting at the touch of a button.
• Built-In Protection: Five electronic temperature sensors help protect against overheating and automatically switch the heater off if water flow stops.

Smart Heating System

Aquael’s Smart Heating System intelligently adjusts heating power to the aquarium’s requirements. This helps avoid sudden temperature changes that can stress aquarium inhabitants and supports smooth, energy-conscious operation.

External Installation

Installed outside the aquarium on the outlet hose of an external canister filter, the Aquael Flow 2.0 Heater leaves the tank interior clear of heating equipment. Heated water is carried back into the aquarium by the filter’s return flow, helping spread warmth evenly throughout the tank while keeping your aquascape uncluttered.

Safety & Convenience

Each heater is tested and calibrated in the Aquael laboratory and manufactured in accordance with strict European safety standards. Electronic temperature sensors monitor operation and automatically turn the device off when water flow stops.
