Hydor® ETH In-Line Aquarium Heaters

Completely safe, Hydor® ETH in-line aquarium heaters take advantage of a patented thermal technology (PTC) that uses a polymer sheet to uniformly heat water, rather then metal heating elements encased in glass. The thermostat is mounted directly on the unit, so the heater shuts off when a low water flow situation occurs. The temperature setting is controlled with a dial (65–93ºF) with indicator light. Mounts in vertical position only. 

Both in-line aquarium heaters have 3" diameter housings and barbed inlet/outlet. ETH201 has 1/2" inlet/outlet and ETH300 has 5/8" inlet/outlet. Safe for use in salt water. UL-listed and CE-approved. 115V/60 Hz with a 6' cord. Made in Italy, one-year warranty.
