Eheim Thermocontrol e 200 Heater
The obvious ideas are often the best. This also applies to the aquarium heating element. It is simply hung in the water and heats it up. The principle is the same as it was decades ago. But in the meantime, the EHEIM controller heater has become an ultra-modern thermal device. The temperature can be set precisely and is measured even more precisely and kept more constant by the electronics. The coating made of special laboratory glass increases the heating surface, serves as a heat shield and ensures even heat emission.

The heater works very steadily and keeps my 300L tank at a consistent temperature. The installation was simple and the temperature control is accurate. No fluctuations even during colder days.
Owen Fisher –
I’ve used this heater for over six months and it’s performed reliably. The glass coating helps distribute heat evenly, which prevents hot spots in the tank.
Olivia Smith –
Great precision in temperature control. I set it to 28 degrees and it stayed there without any spikes. Works well with my planted tank setup.
