Eheim Thermocontrol 25W – 300W

• Precise temperature control – dial at the top of the heater (65-93F or 18-34C)
• Heating function is indicated by an on/off control light
• Chrome Nickel coil inside a shock-resistant shatterproof glass tube

Obvious ideas often are the best ones. For example, the aquarium heater as a rod. The heating rod is simply hung in the water and heats it.

It is true that the principle is still the same as decades ago, but a lot has changed in the meantime.

Today the EHEIM adjustable heater is an ultra-modern electronic thermal device with the best available technology.

A jacket made from special laboratory glass increases the heating surface, serves as a heat shield and ensures optimum even heat emission, no matter if you want to heat a 20 or a 1000 litre aquarium.
