Frequently Asked Questions

In general, these are electric heating units, which heat the room where they are installed, using the natural movement of warm air (so called convection). These units have no fans which makes them practically silent. They are equipped with a heating element , situated in the lower part. The incoming air gets warm and following the natural forces, lifts up and goes out of the unit through special outlets on the panel. The even heat distribution creates a feeling of comfort, without sensation of any air flow.

Radiant electric heaters transfer warmth from their heated surface directly to people and objects in the room, through infrared rays. The effect is the same as the sun glow or the fire in the fireplace. Radiant heating has significant advantages to conventional heating with radiators or heaters: it is more effective because there is no energy loss for warming the air, whereas the lack of moving air provides comfort for people.

Atlantic electric heaters can be equipped with 3 different types of thermostats:

  • Standard mechanic thermostats are easy to operate and allow maintaining of stable temperature in the room, optimizing the energy consumption.
  • Electronic thermostats maintain the set temperature with deviation of 0.1°C, which makes them 15% more energy-saving, compared to standard thermostats.
  • Digital electronic thermostats control the heater with precision by switching automatically between Comfort and ECO modes and provide not only stable temperature in the room but also 25% less energy consumption, compared to standard thermostats.

The necessary heating (cooling) capacity can be calculated, considering various parameters of the ambience – volume and position of the room, construction type, isolation, windows area, additional heaters etc. However, approximate calculations can be made, depending only on the volume. In this case is advisable to consider 45kW per cubic meter. For example, if the room volume is 35 cu. meters, the necessary heating (cooling) capacity is approximately 1500W.

The heat pump is a unit, which transfers heating energy. Actually, heat pumps are identical to refrigerant units, with the significant difference being that t here is no waste of accumulated heating energy. Each heat pump has several most important components: compressor, condenser, direction valve, evaporator. The heat is transferred as the refrigerant changes aggregate state, which results in emission or absorption of heat energy.

The basic principle of operation is as follows:
The components of the heat pump are connected by copper pipes, in which the refrigerant circulates. Gas refrigerant of low pressure and temperature is sucked by the compressor and boosted to 15-25 bar, which results in the increase of its temperature to 45-50°C. Afterwards, the refrigerant enters the condenser where it’s forcedly blown and the heat is transferred to the airflow. After the heat is emitted, the refrigerant condenses. From the condenser, the refrigerant passes through the direction valve, where the temperature and pressure decrease and the refrigerant starts to evaporate. After the direction valve, the refrigerant enters the evaporator. There, it continues to evaporate until vaporizing to gas which leads to heat absorption. The gas of low temperature enters the compressor and so the cycle repeats.

The thermodynamic water heater is equipped with a heat pump. It uses calories from the air to heat the water - a free, natural and inexhaustible energy. The thermodynamic water heater is extremely energy efficient. For each 1kW of consumed energy it produces 2 and 5kW of heating energy, resulting in 80% of energy savings per year.

A DC-inverter has the function of constantly adjusting the heating or cooling capacity by gradually changing the speed of the compressor. ON/OFF air-conditioners are equipped with a compressor that works either at full or at minimum capacity, or switches on and off in order to maintain the set temperature. They also use a thermostat that switches on and off the compressor when the temperature in the room is too different from the desired one. DC-inverters are much more energy-efficient and quieter, their components have longer operation life.

Exclusive O’Pro technology: passive electronic anti-corrosion system (Ohmic resistor)
The ohmic resistor is a passive electronic anti-corrosion device. It balances out the electric potentials of the tank and immersion heating element. The magnesium anode life is considerably increased and protection against corrosion is reinforced.

Patented ACI Hybride system: state-of-the-art titanium anode
The Anti-Corrosion Integrated (ACI Hybrid) system provides maximum protection for the tank. The titanium anode located at the center of the appliance is driven by an electronic PCB that produces a milivoltage electric current. providing the tank with a lifetime protection, replacing magnesium anode.

What is ErP?

The acronym ErP stands for Energy related Products. It is linked to the Ecodesign directive of the European Union concerning this type of equipment. The Ecodesign defines minimum efficiency requirements for energy-related products such as water heaters, heat pumps, boilers and solar water heaters. All manufacturers must comply with this new directive by September 26th, 2015.


Energy savings and environmental protection will be the main challenges for the European Union for years to come. In this matter, as some heating and water heating products can be very energy- consuming, the goal of the new European directive, also called the 20-20-20 target, is to:

  • Decrease CO² emissions by 20%.
  • Reduce the use of primary energy by 20%.
  • Increase renewable energy share by 20% by 2020.

Ultimately, as regards heating and water heating products, the result of these new standards will be an annual energy saving in Europe of around 56 Mtoe (Million tonnes of oil equivalent) by 2020. It represents roughly 20% of France total annual primary energy consumption*.


Ecodesign Directive

Ecodesign defines the acceptable energy efficiency levels, as well as environmental requirements for energy- related products. Therefore, heating and water heating products must comply with all Ecodesign requirements in order to get the CE mark and be sold within the European Union market.

Ecodesing also aims at excluding all low performance energy-using equipment from the market.

The ErP Ecodesign will apply to the following products:

  • Renewable energy water heaters (solar, heat pump)
  • Electric water heaters
  • Heat pumps with a rated heat output ≤ 400kW

Energy Labeling Directive

Well known to the end-user of white goods, energy efficiency label becomes mandatory for all heating and water heating products, within the EU market, from September 26th, 2015. These products must have energy efficiency labels which will inform end-users about their performance. It will create much more transparency for customers and help them make the right choice, for their purchase, by taking into consideration their real performance level (energy consumption, noise level and other product-specific information).



Energy Labeling

The product's label is provided by the manufacturer. In European Union the end-user's contact (distributor or installer) is responsible for providing visibility and comprehension of the ErP label content.

Depending on product’s functions, the label will show two different classifications: one for heating and one for water heating.


As an expert in water heating, thermal insulation and temperature control, Atlantic owns several exclusive patented technologies. It welcomes and actively supports the new ErP regulation. Therefore, all Atlantic water heaters, heat pumps and solar water heaters are ErP-ready!

Moreover, Atlantic is prepared for the future ErP requirements of 2017 with its Alféa range of heat pumps which are already rated A+ and A++.
