Find a productProduct description
This inline heater is meant for keepers running an external filter who want to heat a 300–1000 L aquarium without placing equipment inside the tank. It attaches to the filter's outflow hose, so the water is heated before it returns to the tank and spreads through the whole volume.
Why it matters
- Smart Heating System (SHS): a microprocessor adjusts heating power to hold the set temperature, which keeps the water temperature steady without sudden swings.
- Precise thermostat: the electronic thermostat works within ±0.5 °C across the 20–33 °C range, and the One Touch System sets the temperature with a single button.
- Three temperature sensors: two electronic sensors and one thermal fuse protect the tank from overheating.
- Automatic shutoff: the heater switches off when water flow stops, so it does not run dry.

What it works with
The heater is designed for freshwater and marine aquariums in the 300–1000 L range that are run with an external filter and hoses of 16/22 mm or 19/25 mm. Because it is installed outside the tank, it is a practical choice for setups where interior space is limited or the aquascape should stay uncluttered.
