£67.99

The unique 300W Hydor external heater (16mm couplings) which is suitable for aquariums up to 300 litres and incorporates the exclusive PTC (Positive Thermal Coefficient) technology. The self-limiting PTC heating element guarantees maximum safety against any risk of overheating.

The unique 300W Hydor external heater which is suitable for aquariums up to 300 litres and incorporates the exclusive PTC (Positive Thermal Coefficient) technology. The self-limiting PTC heating element guarantees maximum safety against any risk of overheating. The exclusive technology and the high quality of the components guarantee a long lasting product. Suitable for canister filters and sump tanks.

The ETH heater must be installed outside the aquarium. It can easily be installed within the delivery tube of an external filter or sump return pump, by cutting the tube and linking the two parts to the 16mm connectors of the heater.

Once you have identified the correct place for the ETH heater, make sure it is positioned as upright as possible, never horizontally, and make sure that the arrow on the body of the heater is pointing in the same direction as the flow of water into the tube of the filter on which the heater is placed.

Re-activate the recirculation of the aquarium by connecting the new heating system to the mains.

Set the desired temperature for the aquarium by turning the regulator knob.

The ETH does not require any particular maintenance operations. However, regular cleaning of the inside of the heating tube will prevents the formation of limescale and algae, thus guaranteeing optimal heat exchange during the heating stage.

Also available:

  • Hydor ETH External Aquarium Heater 200 (12mm couplings)
  • Hydor ETH External Aquarium Heater 200 (16mm couplings)
