Eheim Jager Heater Review

Choosing an aquarium heater can be difficult because there are so many options.  Over the years I have tried many brands but I had always been a fan of Ebo-Jager heaters.  Recently I finally bought new ones as my existing Ebo-Jager aquarium heaters that are 10 plus years old have started to have issues.  First off Ebo-Jager aquarium heaters are now Eheim Jager heaters.  I believe Eheim ended up buying the Ebo-Jager brand.  I had purchased a 50 and 250 watt versions. They also make a 25, 75,100,125,150,200, and 300 watt versions. On to the review. The heater is packed nicely and in the box is the heater, suction cup mounts and an instruction manual.  The heater looks well built  and has a nice long (6ft) power cord. It has a temperature range from 64-93F with and accuracy of plus or minus 0.5F.  The Eheim Jager aquarium heater is fully submersible and has a recalibration feature that allows to to correct the temperature setting of the aquarium heater if necessary. The heater is easy to use first set the heater temperature, then attach the suction cup holder to the heater and suction cup it to the aquarium glass.  Let the Eheim Jager aquarium heater sit in the aquarium unplugged for 15 minutes.  After the 15 minutes plug in the heater and it should be set and ready to go.  I like to double check the temperature setting with a good thermometer after the heater has been plug in for an hour or two. If the temperature of the thermometer and the heater setting do not match you can follow the instructions to recalibrate it.  It is pretty easy to do. After using these new heaters for a few months I could not be happier with the results.  The aquarium's temperature is stable and I have had no issues.  If you are looking for a good quality easy to use heater this is one that I would recommend.
