With the EHEIM precision heater your fish receive exactly the right temperature – in any aquarium.Obvious ideas often are the best ones. For example, the aquarium heat-er 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. And today the EHEIM adjustable heater is an ultra-modern electronic thermal device with the best available tech-nology. A jacket made from special laboratory glass increases the heating surface, serves as a heat shield and ensures optimum even heat emission. And no matter if you want to heat a 20 or a 1000 litre aquarium – you have 9 sizes to choose from.

The temperature can be precisely set from 18 to 34 °C and if required recalibrated (±2°). The temperature control accuracy is ± 0,5 °C. The heat is kept at a constant level. The heating function is indicated by a control lampThe rod is absolutely watertight, can be fully submersed, has an automatic dry run shut-off (Thermo Safety Control) and is suitable for fresh and salt marine water.  One of the most important innovations is the glass jacket: -    It increases the heating surface, -    condenses the heat, ensures optimum even heat emission and-    forms a heat shield (touching it doesn’t harm the livestock).The jacket is made from special laboratory glass, which was developed for research purposes. Therefore it is free from pollutants that could be released into the water. It is resistant to chemical and biological  substances. It doesn’t have any fissures and hair cracks through which conden-sation could penetrate. And even extreme fluctuations of temperature that can occur during a water change do not harm this glass

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.

Before the engineer Eugen Jäger invented the aquarium heater decades ago, there was no really satisfactory solution to produce the appropriate water temperature. They dealt with complicated and sometimes curious methods. Some put the aquarium in the sun or by the heater or stove. The EHEIM thermocontrol aquarium control heater is a further development of the legendary heating element and thermocontrol-e is the latest electronically controlled variant. The temperature can be precisely adjusted from 20 to 32 °C. The control accuracy is ± 0.5 °C. The heat is kept constant. A control lamp indicates the heating function.The heater is absolutely waterproof, can be fully immersed, has a dry run protection (Thermo Safety Control) and is suitable for fresh and marine water. One of the most important innovations is the glass coating:  •    It increases the heating surface, •    compresses the heat, ensures optimum, uniform heat output and •    forms a heat shield (the aquarium inhabitants do not mind touching it). The coating is made of special laboratory glass. This was created for research purposes. It is therefore free of pollutants that could be released into the water. Chemical and biological substances do not attack it. There are no cracks and hairline cracks through which condensation water could pass. It is impact resistant. And even extreme temperature fluctuations, such as those that may occur during water changes, do not affect this glass.

With the EHEIM thermocontrol-e heating element your fish get the right temperature even more precisely - in every aquarium. The obvious ideas are often the best.

With preset comfortable temperatureIt could not be simpler: With the EHEIM aquarium heater thermopreset the comfortable temperature for the aquarium inhabitants is preset. Your tank keeps constant 25 degrees celsius. This is also the optimal temperature for the keeping of the most common aquarium inhabitants. The electronic control guarantees an extremely high precision / temperature accuracy, the highly efficient heating element ensures an even heat distribution. The EHEIM thermopreset bar heater is different from the EHEIM thermocontrol due to the additional plastic protection which ensures high mechanical stability. As usual from EHEIM, both heaters are equipped with an LED light to control the heating function and a dry-running protection.  The new heater is available in four different performance classes, which are indicated by the number in the product name: thermopreset50 (50W), thermopreset100 (100W), thermopreset150 (150W) and thermopreset200 (200W).  Common to all variants is the slim design – with a diameter of only 2,8 cm and a length of 17 to 25 cm, the heater is hardly visible also in small basins. Advantages of the EHEIM thermopreset heater High user-friendliness thanks to preset temperature Due to short lengths also usable in small tank Very narrow and therefore less visible in the aquarium Plastic protection ensures high mechanical stability  High temperature accuracy due to electronic control Even heat distribution thanks to the highly efficient heating element With dry-running protection A control lamp indicates the heating function Secure fixing by means of the included suction cups Suitable for freshwater and marine water 3 years warranty
