Dennerle Nano Therm 25W

The Dennerle Nano Therm 25W is purpose-built for the unique demands of nano aquariums from 5 to 25L, delivering precise 25W heating from a minimal footprint heater. Its integrated digital thermostat offers accurate temperature control in a size typically reserved for less sophisticated analog units, making it ideal for shrimp tanks, nano planted aquascapes, and small species setups. The compact submersible housing is easily concealed behind hardscape or plants, maintaining the aesthetic integrity of nano aquariums. Safety features include automatic cutoff when exposed to air, preventing heater damage during water changes. An excellent solution for aquarists who refuse to compromise on precision even in their smallest tanks.
