Reglerheizer 100W – aquarium heater with thermostat

This 100W heater with built-in thermostat is intended for keepers of tropical fish in tanks of 70–150 L who need to hold water at a set temperature. The thermostat switches the heater on when the water cools below the setpoint, so the temperature stays stable without manual adjustment.

Why it matters

• The thermostat maintains the set temperature by switching the heating element on when the water drops, within an adjustable range of 12–34 °C.
• The IPX8 rating and full waterproofing allow the heater to work fully submerged, which is required for in-tank installation.
• The temperature dial sits on the top of the unit, so the setting can be changed without removing the heater from the water.
• Suction cups are included, and the heater can be mounted either vertically or horizontally, depending on the tank layout.

What it works with

The heater is designed for freshwater and marine aquariums in the 70–150 L range, and its 100 W output is matched to that volume. Its 3 cm profile is slim enough to position it discreetly among plants or décor. The 17 cm minimum water level should be considered when setting up a tank that will run at lower water levels.
