As you know, fish from tropical and sub-tropical waters require a constant water temperature. Before the engineer Eugen Jäger invented the aquarium adjustable heater some decades ago, there wasn’t any really satisfactory solution for controlling the water temperature suitably for specific species. People resorted to complicated and sometimes odd methods. Some put the aquarium in the sun or next to a radiator or an oven.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°). 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 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 condensation could penetrate. And even extreme fluctuations of temperature that can occur during a water change do not harm this glass.

Innovative Marine is proud to introduce HELIO, their new line of heaters utilizing ultra-safe PTC (positive temperature coefficient) technology. Up until now, the way we chose to heat our aquariums have been electric immersion heaters that use resistance wires as the primary source of heat. This is the same technology commonly used in toasters. When these types of aquarium heaters are exposed to air or become covered with debris, the heat is unable to dissipate quickly enough resulting in a rapid temperature spike, reduction in operation life and eventually catastrophic failure of the aquarium. When developing the HELIO, we looked at the aquaculture industry and how PTC technology was utilized. After scrutinized detailed analysis, we extrapolated how to efficiently heat (in both cost and thermal dispersion), as well as minimizing the danger of air exposure and for everyday use.PTC technology utilizes solid state ceramic chips that are programmed to reach only a certain predetermined set temperature. As compared to resistance wires that continuously increase in temperature until the element ceases. When the temperature of the ceramic chip heating element increases, the sensor on the chip itself reads the increase and will increase its electrical resistance resulting in decreased heat output. This simply means that as the heating element gets hotter, it will become relatively more difficult to become hotter. Safety is inherently built in and not added on. Now, after we reengineered and redesigned as well as incorporated the latest reef aquarium technologies, the PTC self-regulating heater and its components are ready to operate safely and efficiently in a harsh marine reef aquarium ecosystem. The mastermind behind the HELIO Heating System is our PTC smart controller, which bridges the gap between hobby grade and commercial heating systems. The smart controller’s processor goes hand in hand with the PTC heating elements to keep your temperature stable. Communicating back and forth with the elements and alerting you immediately after any fluctuations in temperature have been detected. The PTC smart controller has been fitted with a titanium remote temperature sensor and dual heating element power lines. Since each heating element has its own built in temperature regulation system, there’s safety in redundancy from the controller’s temperature sensor. And if dual heating elements are employed, there is yet another level of safety added to the system.Each piece of the HELIO heating system was created to work harmoniously together. Commercial grade titanium heating sheaths and screws prevent corrosion. Rare earth magnetic heating element holders allow optimal water flow. Quick disconnects for the controller’s temperature sensors and heating elements make for easy maintenance and upgradeability.After years in development, the HELIO heating system possesses powerful features that exceed current reef aquarium heater expectations and achieve three main objectives: Increased safety. Improved reliability. And to provide a new reef aquarium heating technology superior to the long held standard. HELIO PTC Titanium Heating System. Smart. Safe. Stable.

The HELIO smart controller bridges the gap between hobby grade and commercial controllers. Its processor goes hand in hand with the titanium sensor to keep your temperature readings stable. The controller comes fitted with a titanium remote temperature sensor and dual heating power lines. If the heating element/s of your choosing have their own controlling systems, you can create up to four independent temperature readings... Safety in redundancy. The two power jacks accommodate up to 1000 watts in total for the heating elements that you choose to attach to the controller. A quick disconnect junction for the controller’s titanium temperature sensor make for easy maintenance and upgradeability. After years in development, the HELIO controller helps you attain the optimal homeostatic reef aquarium temperature environment. Three main objectives met: Increased safety. Improved reliability.
