- 1-year Aquarium Co-Op warranty
- Built-in heater guard
- Extra-long, 11.8-foot cord
The Aquarium Co-Op heater comes in two sizes — 50 watt and 100 watt. It is reliable, accurate, and thoughtfully designed to avoid some of the problems we encounter with many other heater brands on the market. If you do run into a problem, Aquarium Co-Op provides a 1-year, hassle-free warranty on this heater.
This compact heater is easy to position within the aquarium and has a built-in heater guard to protect the unit from damage. You can quickly adjust the temperature without getting your hands wet, since the adjustable temperature controller is located in the middle of the power cord and sits outside the aquarium. Plus, the cord itself is extra long and extends 11.8 feet, so reaching the outlet is much easier compared to many other heaters. (The cord length between the heater and controller is 4 feet.)
The heater is intended for indoor use only, so please make sure the tank water is around room temperature before plugging it in. Do not operate or plug in the unit unless the heater is fully submerged underwater.
Note: When you first plug in the heater, a yellow indicator light will briefly turn on and then turn off again. The yellow light will turn on again once the unit has run for 17,520 hours, which is 2 years of being plugged in full time. At this point, the heater will still continue to work, but the yellow light reminds you that it has reached the end of its expected life and it may be time to start thinking about replacing the unit to ensure the highest performance. The red indicator light turns on whenever the heater is actively heating the water, and the temperature display is always on to show the current water temperature.
Aquarium Co-Op Heater
I bought two of these heaters. Love the temp display and the near end of life warning. Had them for a year now and so far no issues.Highly recommend.
Bought 4 of these heaters along with 4 thermometers and these heaters are as accurate as advertised (within 1-2 degrees of error). I like their look, the extra long cord and the extra suction cups provided. Can't speak to their longevity but it is nice knowing they have a year long warranty and a reputable company to back that up.
Best heater I've owned. So much better than a glass tube heater. Where was this 25 years ago?
