This heater suits keepers of small freshwater tanks in the 10–20 litre range who need a stable, adjustable water temperature. The integrated thermostat reduces the need to monitor heating manually and keeps the water at the set value within the 12°C to 34°C working range.
Why it matters
- The stainless steel housing is intended to resist mechanical damage and burnout, and it distributes heat evenly along its length.
- The IPX8 waterproof rating means the unit is designed to work submerged, and it can be placed vertically or horizontally.
- The thermostat has a readable temperature programmer indicator, so the set value can be checked at a glance.
- Suction cups and mounting brackets are included, so the heater can be fixed inside the tank without extra accessories.
