The JÄGER aquarium heater is an ultra-modern thermal device using the best available technology. Now - with in its new jacket of laboratory glass - it offers another an extra quality dimension.

  • The temperature can be precisely adjusted from 18° to 34°C and readjusted if required.
  • The control accuracy is +/- 0.5°C. The heat is controlled to a constant temperature. The heating function is indicated by an on/off control lamp.
  • The heater can be fully immersed, is protected against running dry and is suitable for fresh or marine water.
  • The glass jacket enlarges the geating surface and ensures optimum even heat transfer. Thus, a smaller wattage than other brands will heat the same volume of water.
  • Jacket of laboratory safety glass

Laboratory safety glass was made for research purposes. Therefore, it is free from pollutants, which could seep into the water. It is resistant to chemical and biological substances. It does not have any fissures and hair cracks, which condensation water can penetrate. And it is shatter-proof ie. resistant to cold water shock, which can occur during maintenance or sudden water level changes.

I've always used Jagers and have never been let down performance wise.

Great Heaters. I own 3 at the moment all of different ages and conditions. All work as they should. They are a little tricky to setup if not using a controller. I have 1 one a controller and 1 in my sump working on its own power and thermostat. Its always a good idea to run two smaller heaters to help safe guard your tank from overheating if a heater fails in the On position. I run two 300 watt heaters on a 150 gallon system.

I like this heater because it can be fully immersed so its good for the main display or for the sump. Just make sure the sump can take the heater because its 20 inch long. I have 2 in my 180 gallon.
