You can use EHEIM climacontrol+ to cool down the water temperature on hot days or warm it up on cold days, just as your aquarium inhabitants need it.EHEIM climacontrol+ is our new electronically controlled climate control device. You simply set the ideal water temperature wirelessly - via smartphone, tablet, or PC/MAC. If the water is too warm, the unit automatically cools down, and if it gets too cold it warms up. The unit monitors and controls everything.Also, it gives you advanced warning of any problems, such as if the required temperature is exceeded or undershot by 2 °C for more than 5 minutes, you receive a warning e-mail.High outdoor temperatures often cause the aquarium water to overheat in summer. This is extremely harmful to fish and all other living creatures. For example if the temperature is too high, corals die in the marine aquarium, and in freshwater aquariums, oxygen deficiency and algae proliferation occur quickly.EHEIM climacontrol+ is the optimal climate control device for aquariums. It has low energy consumption and works with environmentally friendly coolant.There are three climate control devices available: S, M and L - for aquariums up to 500, 1000 and 2000 litres and come with a 3-year warranty.Features of the EHEIM climacontrol+ Electronically controlled continuous flow climate control device with Wi-Fi functionality Temperature setting and control over WiFi via smartphone, tablet, or PC/MAC Cooling and heating mode Constant regulation of water temperature Temperature control of water in freshwater and marine aquariums Precise temperature detection from 5 °C up to 35 °C Switches on automatically above or below a set target temperature Warning e-mail if temperature exceeds or falls below 2 °C for more than 5 minutes Constantly displays the current water temperature when in operation Use in the ambient temperature range from 10 °C to 38 °C Very energy-efficient and environmentally friendly climate control devicewith ozone-friendly refrigerant (R290) To be operated exclusively with clean (filtered) water; i.e. for marine aquariums via separate pump with water from the filter tank or for freshwater aquariums position behind the external filter (alternatively via separate pump with pre-filter directly from the aquarium) There are three climate control devices: S, M and L - for aquariums up to 500, 1000 and 2000 litres Made of High quality parts and materials, and comes with 3 years warranty Important for marine water aquariums:Optimum temperature for corals between 24 and 26 °C; above 29.5 °C they die.Important for fresh water aquariums:The temperature should always be below 30 °C. Above this temperature there is a risk of oxygen deficiency, inhibited plant growth, algae proliferation.EHEIM climacontrol+ – the electronically controlled climate control devicewith WLAN function and many advantagesEHEIM climacontrol+ has the main task of cooling down the aquarium water when the temperature is too high. It provides both a cooling and a heating function.In summer, high outside temperatures often lead to overheating of the aquarium water - e.g. in a small room that heats up quickly, in an attic flat, in sunlight, etc. Even in basins that are closed at the top so that the warmth from the lighting cannot escape, there is occasionally a build-up of heat.EHEIM climacontrol+ offers WLAN function. The WiFi controller is used to set the optimum target temperature via smartphone, tablet or PC/MAC. As soon as the temperature exceeds or falls below the target value, the unit switches on and cools or heats the water until the target value is reached. The current water temperature is always displayed. If the set temperature is exceeded or undershot by 2 °C for more than 5 minutes, you will receive a warning e-mail.EHEIM climacontrol+ is a continuous flow unit and should only be operated with clean (filtered) water. For marine water aquariums, this means with water from the filter tank (with a separate pump). In freshwater aquariums by placing it behind the external filter. (Alternatively, operation via a separate pump - but with a pre-filter - directly from the aquarium is also possible here).EHEIM climacontrol+ works energy-efficiently and environmentally friendly. The refrigerant (R290) replaces ozone-depleting coolants and the global warming potential (GWP) is in the minimum range.When positioning the unit, make sure that the ventilation openings are always kept clear. The distance to walls etc. should be at least 50 mm. In the base cabinet of an aquarium combination, for example, appropriate recesses must be provided for fresh air supply and warm exhaust air (for more details, see the operating instructions).ATTENTION! The climate control device may only be stored, transported and operated in an upright position!

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.Benefits of the EHEIM thermostatic heaters Precise temperature adjustment from 18 up to 34 °C Simple and safe recalibration (±2 °C) Temperature control accuracy ± 0,5 °C Heat kept at a constant level Heating function is indicated by a control lamp Completely submersible (watertight) With automatic dry run shut-off (Thermo Safety Control) A glass jacket increases the heating surface and ensures optimum even heat emission Handy cable length ca. 170 cm Including double suction cup holder 9 sizes for aquariums from 20 up to 1000 litres Suitable for fresh and marine water Precision, ease of use, quality and safety “Made in Germany” The EHEIM aquarium heater is a further development of the legendary heating rod.The temperature can be precisely set from 18 to 34 °C and if required recalibrated (±2°).

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. This also applies to the aquarium heating element. It is simply hung in the water and heats it up. The principle is the same as it was decades ago. But in the meantime the EHEIM controller heater has become an ultra-modern thermal device. 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. And whether you want to heat a 20 or 1200 litres aquarium - you can choose from 10 sizes.Advantages of the EHEIM control heater thermocontrol-e Precise temperature adjustment from 20 to 32 °C No readjustment necessary Control accuracy ± 0.5 °C The heat is kept constant Control lamp indicates the heating function (red: heating up; green: temperature reached) Fully submersible (waterproof) With dry-running protection (Thermo Safety Control) Glass coating increases the heating surface and ensures optimum, even heat output Convenient cable length approx. 170 cm Including double suction holder 10 sizes for aquariums from 20 to 1200 litres Suitable for fresh and marine water Highest safety and reliability - 3 years warranty   Precision, comfort, quality and safety.As you know, fish from tropical and subtropical waters need a certain constant water temperature. 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.
