Hydor ETH In-Line Aquarium Heater
The Hydor ETH external in-line Heaters are the first aquarium heaters designed with the exclusive PTC technology. The self-limiting PTC heating element guarantees maximum safety against any risk of overheating. The ETH must be used in a vertical manner for correct operation. For most common application it is designed to be installed on return lines coming from canister filters, however the ETH is easily adapted for use in almost any situation where heated aquarium water is required, such as with wet/dry sump pumps and aquaponics.
The ETH heats with high efficiency by means of an internal heat pump system that avoids temperature variations. For use in freshwater and marine aquariums. Fits most canister filters such as the Hydor Prime, the Rena Filstar, Eheim canisters, and the Fluval canisters with the use of a short section of tubing to complete the connection.
Where should I install my ETH HEATER?
The ETH heater must be installed outside the aquarium. It can easily be installed on the delivery tube of your external filter, by cutting the tube and linking the two parts to the connectors of the heater.
How should I install my ETH 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.
