Flowheater

Say goodbye to bulky equipment ruining your carefully crafted aquascape. The Aquael Flow Inline Heater moves your heating system entirely outside the tank. By seamlessly installing directly onto the return hose of your external canister filter or sump system, it leaves your display completely unobstructed while distributing heat evenly throughout the entire aquarium. 

Driven by an industry-first Smart Heating System (SHS), this intelligent inline heater continuously reads your tank’s conditions and dynamically adjusts its power output. Instead of aggressive, stress-inducing temperature spikes common in traditional heaters, it ensures a smooth, highly stable environment for your sensitive fish and plants—all while optimizing energy consumption. Equipped with a dual-purpose LED screen that acts as both a thermostat and a digital thermometer, it keeps you fully informed by displaying both your target setting and the current real-time water temperature.
