Description
Product Details

The resistance of the EHEIM Thermopreset differs from the EHEIM Thermocontrol due to the additional plastic protection that ensures high mechanical stability. As usual with EHEIM, both heaters are equipped with an LED light to control the heating function and a dry-running protection.

Advantages of the EHEIM Thermopreset heater:

High resistance thanks to preset temperature
Due to small size also usable in small ponds
Very narrow and therefore less visible in the aquarium
Plastic protection ensures high mechanical stability
Accuracy at high temperature thanks to electronic control
Even heat distribution thanks to the highly efficient heating element
With protection against dry running
A control lamp indicates the heating function
Secure attachment using the included suction cups
Suitable for fresh and marine water
3 years warranty
