The challenge is to create an aquatic ecosystem to maintain the temperature without oscillations. Tropical and subtropical water fish need constant water temperature. Before engineer Eugen Jäger invented centuries ago the adjustable aquarium thermoheater, there was no really satisfying solution that would produce a water temperature adapted to each species. It was solved by complex and sometimes curious methods. Some put the aquarium under the sun or next to the heating or oven. The EHEIM adjustable aquarium thermoheater is a further development of the legendary bar heater. With the EHEIM precision adjustable thermoheater the fish receive the right temperature in each aquarium. Below you can see the main features of this aquarium thermowarmer: 1. The temperature can be adjusted exactly from 18° to 34° C and given the case can be reset (±2°). Accuracy is +/- 0.5° C. Using the ring (blue) adjust the temperature. 2. It has a control lamp where the thermoheater operation will be shown. 3. Its design is designed to be completely submersible (watertight). 4. Thermo Safety Control 5. The glass coating increases the heating surface and ensures optimal and balanced heat transmission. 6. For more comfortable use and continue it has a cable length of approximately 170 cm. 7. The way of fastening and fixing the thermo-heated is through a double suction cup that comes included in the product. 8. Features a variety of sizes for cuber. Review: Fantastic. - I believe I have written a review for these previously. Fantastic item, very good quality materials and very capable. Example: you may have an inferior thermostat that was cheaper say, 300 watt to power a 300 - 400 litre aquarium when a 100 - 150 watt eheim item would do the same job. Therefore you're using alot more energy to do the same job which is more expensive in the long run and less consistent meaning you will have a higher degree of temperature fluctuations. This is an example, you can get the exact product specifications on the eheim website to size correctly.
