Reglerheizer 200W – aquarium heater with thermostat

This 200 W heater with an integrated thermostat is intended for aquarium keepers who need to hold a stable water temperature in tanks of 150–350 litres. Its fully submersible design and suction cup mounting allow it to be placed inside the tank without a separate external controller.

Why it matters

• The thermostat switches the heating element on when water temperature drops and holds the temperature you set, within the device's working range of 12–34°C.
• The IPX8 waterproof rating and full submersion capability mean the unit can run continuously under water, with no need to keep any part above the waterline.
• The temperature knob sits on the upper section of the heater, so the setting can be changed without reaching deep into the tank.
• Suction cups are included and the heater can be mounted vertically or horizontally, which makes it possible to position it where water circulation is adequate.

What it works with

The heater is sized for aquaria in the 150–350 L range and is suitable for both freshwater and marine tanks. Because the device is rated for a minimum water level of 21 cm, it should be used in tanks that meet that depth requirement. Smaller tanks should use one of the lower-wattage models sold separately, as this listing covers only the 200 W version.
