Eheim Thermopreset Heater Range
It could not be simpler: With the EHEIM aquarium heater thermopreset the comfortable temperature for the aquarium inhabitants is preset. Your tank keeps constant 25 degrees celsius. This is also the optimal temperature for the keeping of the most common aquarium inhabitants. The electronic control guarantees an extremely high precision / temperature accuracy, the highly efficient heating element ensures an even heat distribution.
The EHEIM thermopreset bar heater is different from the EHEIM thermocontrol due to the additional plastic protection which ensures high mechanical stability. As usual from EHEIM, both heaters are equipped with an LED light to control the heating function and a dry-running protection.
