Hydor Theo 100W Aquarium Heater

The most powerful aquarium heater from Hydor's Theo range that we sell is this 100W aquarium heater, capable of heating aquariums from 50 - 100 litres capacity in a safe and precise fashion.

At just over 20cm in length, this heater has incredible potential, capable of heating aquariums holding a maximum of 100 litres of water. It is not recommended, however, to use this heater to heat aquariums with less than 50 litres of water, as it is simply too powerful! The temperature itself is measured in °C, with a minimum setting of 20°C and a maximum of 32°C. The heater also sports impact resistance and is shatterproof.

Able to be used in freshwater or marine water (saltwater) your heater is also fully submersible. It can be positioned vertically or horizontally using the 2 suction cup mounting clips that are provided to suit your preference. When submerging your heater, ensure water goes at least up to the indicated minimum level line if it is not fully submerged.

The exclusive PTC technology as well as the quality of components ensures this heater will last for years to come.
