Water heaters technologies


Atlantic efficient and reliable anti-corrosion system

The O’Pro passive electronic anti-corrosion system provides a good protection and extended service life for your water heater and contributes to your comfort and savings.

The ohmic resistor of the O’Pro technology, is a passive electronic anti-corrosion device. It balances out the electric potentials of the tank and heating element. The magnesium anode life is, therefore, considerably increased and the tank protection against corrosion is reinforced.

The exclusive O’Pro technology is a modern generation of passive electronic anti-corrosion protection for your DHW production appliance.

« Our permanent quest for technical innovation and efficiency is fully reflected in our DHW production and water heater technologies! »

The O’Pro technology guarantees that your DHW production appliance has a long service time without failure. You can even expect a +50% tank lifetime!

Aggressive waters generate corrosion, balanced waters create a natural protection for the appliance and hard waters generate large scale deposits. O'Pro technology is adapted to all! Perfect for balanced waters, it is also recommended for aggressive and hard ones.

Consequently, O'Pro is also fully part of your comfort and savings regarding DHW production.

Loic, our DHW production and water heater technologies specialist at Atlantic Paris: « With our exclusive O’Pro technology, both the life of the magnesium anode and the protection of the tank are increased! ».

Atlantic ceramic heating technology for your comfort

Atlantic develops the Steatite exclusive patented technologie achieving long-lasting service in the day-per-day use, as well as optimum efficiency & savings.


Water is a chemical agent charged with positive and negative ions. When the number of ions is balanced, the water charge is neutral.

However, depending on region, water supplied isn’t always balanced. Aggressive, highly mineralised and hard water can create corrosion or scale, reducing the performance and lifetime of your water heater.

With Atlantic Steatite technology, you don’t have to worry about it anymore. The Steatite heating element is particularly well adapted to unbalanced waters thanks to:

No direct contact with the water

Large heat exchange surface that reduces scale deposits

With Atlantic Steatite technology, you water heater will remains performant and long lasting, in harsh conditions



Over time, from soft or hard the water tends to return to balanced type, by rejecting the particles it contains in excess.

In case of soft-aggressive water, the aggressive particles in excess, attack the metal tank trough the natural microscopic cracks of the enameling. In time this leads to a tank leak.

Analogically, in case of hard water, the protective particles in excess accumulate on the tank walls and form a protective film. Despite its bad image, in limited quantity the limestone protects the water tank from corrosion.

The Steatite heating element is protected by enameled steel sleeve. This is granting a large heat exchange surface, which reduces heating noise. Its replacement does not require the water heater to be drained down for maintenance, a genuine bonus for an easy maintenance.

With Atlantic Steatite technology, enjoy hot water without functioning noises or maintenance nightmares!


Atlantic provides the widest range of water heaters fitted with Steatite technology, so to provide you with a solution tailored to your precise need.

Steatite water heaters are equipped with heating elements powered from 1200W to 3000W, for you to benefit from fast water heating no matter the outside temperature.

And the ranges include from 30L to 300L capacity tanks, so you and your family will never run out of hot water.

In addition, the specificities of each range guaranties an adapted solution to your installation dimensions requirements.

With Atlantic Steatite ranges, find a tailored solution to your hot water requirements

Diamond-quality enamel

The first protection of your tank by Atlantic

The first role of enamel is to protect hot water tanks, steel sleeves (in Steatite technology...) or other elements of DHW appliances from scale deposits and rust.

A low quality tank has much higher risk to corrode and to malfunction. In that respect, to obtain the ideal thickness of enamel is very important too. Indeed, if the thickness is too thin, the corrosion will occur by dilution of enamel. If it is too important, the corrosion will occur by cracking of enamel.

It is, therefore, tremendously important to use the best possible quality of enamel in order to ensure robustness, proper operation and long life to your water heater.

The diamond-quality defines our high resistance enamel. It guarantees a long service time, without failure, of your hot water tank.
The diamond-quality enamel refers to both our know-how on that technology and the composition of our enamel. Indeed, the zirconium contained in the enamel we use is also used to create artificial diamonds!

Loic, our DHW production and water heater technologies specialist at Atlantic: « With our diamond-quality enamel, you can rest at ease. Your water heater is perfectly protected and will have an extended service life without failure! ».« Our new generation diamond-quality enamelling ranks among the best of its kind worldwide! »

Regarding our know-how, in order to produce diamond-quality enamel, we have conceived a set of highly sophisticated procedures:

- The preparation and cleaning of the steel inner surfaces before enamelling use 30 bars shot blasting or compressed air cleaning techniques.

- The coating techniques consist in flow coating rotating process (small capacity water heaters), running ball technique (floor standing, large capacities, combi & indirect) and spray technique with pulverised electrostatic powder (medium capacities).

- The key to obtain the best enamel possible is by avoiding that the water contained in the enamel escapes suddenly, hence it is necessary to decrease its porosity. The techniques used to achieve this objective are: air jet at 60°C, steaming at 140°C and cooking at 850°C.

- In order to ensure the best possible quality, our enamel is subject to strict quality controls: during each preparation, quality control of enamel after reception (density, fineness…), for each serie, control of the enamel layer thickness after cooking and for each product, visual control of the inner tank surface before assembly.

« Atlantic has chosen an ecological solution, far safer than acid scouring, for its enamelling! »
