The new Eheim thermocontrol-e heater is an electronically controlled version of the company’s thermocontrol heater line. This new version has all the advantage of the flagship heater with even more accurate control and safety.
While the previous version was a popular option for decades, the recent advances in electronic control allows for a more state-of-the-art heating device. The temperature can be adjusted precisely and is in smaller increments accurately to ensure a more consistent temperature.
According to the company, the glass sleeve is made of special laboratory glass designed to increase the heating surface, while serving as a heat shield for a more uniform heat transfer.
Like its other heaters, there are options whether you want to heat a 5 to 300 gallons or somewhere in between, with 10 sizes to choose from.
