INLINE AQUARIUM HEATER WITH ADVANCED TECHNOLOGY
Hydor have invented the first and unique external heater for aquariums with 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.
200 watt - 100-200 litres
300 watt - 200-300 litres
Why buy an inline heater?
If you want the focus of viewers to be on the efforts and the beauty of the design you created within your aquarium and not on all of the necessary hardware needed to keep your aquarium then this is the ideal chance to minimize the amount of hardware in the tank.
The Hydor ETH 300 In-Line Heater solves this problem very easily.
As the ETH heaters connect to the outflow of any canister filter or the return from any sump to the tank. This evenly distributes heat throughout the aquarium while staying neatly hidden beneath your aquarium in the cabinet.
The Hydor ETH 200 or 300 In-Line Heaters are rated at either 200 or 300 watts. Conventional wisdom suggests that 300 watts would be sufficient for up to a 270 litre / 60 gallon aquarium. Many have applied this theory for years but it is quite conservative for an in-line heater. The circulation through this heater allows it to work much more efficiently. I am currently using a ETH 300 on a 90 gallon aquarium in a room that drops to the mid-50's overnight and the heater had no problem maintaining the 78 degrees I have set.
Setting the Temperature
Setting the temperature on the heater is so simple. No more wet hands!!
Setting the working temperature is done using the red dial on the outside of the heater. The temperature settings are clearly marked and once it is set the unit is found to be very consistent.
As with most aquarium heaters a red LED lets you know when the heater is on.
The Hydor ETH In-Line Heaters are constructed from a durable plastic.
Inside is a glass tube through which the water passes. Wrapped around the glass tube is a conductive heating element that heats the water as it flows through the tube.
Each end of the glass tube is attached to a connector and sealed with a rubber gasket.
The connectors are designed to clamp perfectly onto the filter tubing the sizes are shown for each model.
220/240V UK plug.
