Atlantic water heaters & thermodynamic tank
Replacement and installation of Atlantic electric water heaters and thermodynamic tanks in Lille and the metropolitan area. Discover our projects and find the right solution for your home.
All Atlantic water heaters, from compact to thermodynamic
At HFE – Hecker & Frères Énergie, we handle the replacement and installation of all types of Atlantic electric water heaters to suit every home. Whether you live in a studio, flat or family house, we select the right capacity to ensure optimal hot water comfort while keeping energy consumption under control.
Why choose Atlantic?
- Recognised French manufacturing
- Excellent reliability and longevity
- Wide choice of capacities and formats
- Spare parts readily available
- Optimal domestic hot water comfort
Vertical and horizontal tanks 50 to 300 litres
Traditional Atlantic water heaters are available in many capacities:
- 50 to 100 litres: perfect for one to two people.
- 150 to 200 litres: suited to a family of 2 to 4.
- 250 to 300 litres: recommended for larger families with high hot water demand.
These models offer excellent reliability, good thermal insulation and everyday comfort.
Atlantic slimline tanks 40 to 120 litres
When space is limited, Atlantic slimline water heaters are the ideal solution. Their shallow depth allows installation in a bathroom, cupboard or utility room while maintaining substantial capacity.
Available in:
- 40 litres
- 65 litres
- 80 litres
- 100 litres
- 120 litres
Their modern design and optimised heating time make them especially popular in renovation projects.
Atlantic thermodynamic water heater
To go further on energy savings, the Atlantic thermodynamic water heater (TWH) combines a hot water tank and a mini heat pump. It captures heat from the surrounding air to produce domestic hot water — up to 70% savings compared with a standard electric tank. Cellar installation is often preferred to optimise performance and simplify servicing.
A complete, safe installation
With every replacement, we check the entire installation and replace where necessary:
- Safety group
- Pressure reducer
- Domestic expansion vessel
- Hydraulic connections
- Condensate drainage depending on the model
We also remove the old water heater and commission the new equipment.
The right tank for your home
Thanks to our expertise, we help you choose the Atlantic electric water heater or thermodynamic tank best suited to your home and usage habits to ensure performance, savings and everyday comfort.

About this installation
As part of this renovation, we replaced the old electric water heater with an Atlantic thermodynamic unit, significantly reducing the energy consumption associated with domestic hot water production.
The tank was installed in the property's cellar — an ideal location to optimise performance and facilitate maintenance. To protect the installation and extend its service life, we also fitted a domestic expansion vessel. This absorbs water expansion during temperature rise, limiting overpressure in the system and discharge at the safety group.
This project gives the client a modern, economical and durable solution for domestic hot water while ensuring reliable, high-performance daily operation.

About this installation
On this project, we replaced an end-of-life electric tank with an Atlantic thermodynamic water heater. The goal: cut domestic hot water running costs while maintaining a comfortable reserve for the whole household.
The installation was carried out in the cellar, with replacement of the safety group, hydraulic connections and a suitably sized expansion vessel. The system was checked, bled and commissioned the same day.
The client now benefits from more economical hot water production eligible for MaPrimeRénov' and CEE grants, with reliable Atlantic equipment that is easy to service.
