Chihiros Lämmitin PRO (0–1000 W) – 16/22 mm

Chihiros Heater PRO heats aquarium water as it flows back from the external filter. The warmed water is distributed throughout the aquarium by the filter outlet, supporting even temperature without a visible glass heater inside the display tank.

The 16/22 mm model connects to standard external-filter tubing with an approximate 16 mm internal and 22 mm external diameter.
