Ingenious: Forget the separate heater in the aquarium thanks to this thermo filter.
An ingenious innovation: the water is sucked in, filtered, heated at the same time and flows back into the aquarium at exactly the right temperature. As a pioneer, Eheim has once again succeeded in realising this revolutionary idea to technical perfection. We are the only company to offer external filters with an integrated heating system (IHS). There are currently 5 thermo filters of the Eheim professionel generation (professionel, professionel 3 and professionel 3e) for aquariums from 120 to 1200 litres. So you have all the advantages of these high-quality filter series plus the convenient Thermo function.
Filtering and heating - all in one.
Eheim Thermo external filters - unique in the world. Cleaning, circulation and precise temperature control at the same time: Only Eheim offers this. The highlights of our professionel filter generation.
