Hecker & Frères Énergie (HFE) installs and renovates centralised heating systems in co-owned buildings: collective heat pumps, high-performance boilers and domestic hot water. Cut charges for every co-owner with dedicated grants.
In co-owned buildings, heating is often the largest shared expense. HFE designs and installs collective heating solutions tailored to your building: centralised air-to-water or water-to-water heat pumps, high-efficiency condensing boilers, and shared domestic hot water production.
A well-sized centralised system gives every unit consistent comfort while sharing the investment and maintenance costs. With 2026 grants, now is the ideal time to upgrade your building's installation.
Replace an oil/gas boiler with a centralised heat pump for the building's heating and hot water.
Collective tank, heat exchanger or thermodynamic heater for efficient, economical hot water.
Pipe insulation, hydraulic balancing, thermostatic valves and individual metering to optimise every unit.
Annual contract for boiler room monitoring, preventive maintenance and rapid breakdown response.
Thermal evaluation of the building, work recommendations and support for the property manager with grant applications.
MaPrimeRénov' Copropriété is a French government grant specifically designed for energy renovation of collective buildings. Combined with CEE, it dramatically reduces each co-owner's out-of-pocket cost.
Collective grant paid to the co-owners' association, capped at €25,000 per dwelling over 5 years. 30% rate for ≥ 35% energy gain, or 45% for ≥ 50% gain.
10% bonus if the works take the building out of thermal sieve status (EPC band F/G to D or better after works).
20% bonus for financially distressed co-ownerships (high arrears rate, safeguard plan).
CEE (energy saving certificates) grants paid by energy suppliers, stackable with MaPrimeRénov' Copropriété.
HFE supports your property manager in preparing MaPrimeRénov' Copropriété and collective CEE applications. Final amounts are set by the Anah and CEE delegates based on your situation.
An efficient collective heating system can cut energy bills by 30 to 60% compared with an ageing oil or low-temperature gas boiler.
Consistent temperature in every apartment, better regulation and individual metering to empower each co-owner.
A better EPC rating increases unit value and secures rental ability (progressive ban on thermal sieves).
Costs are split between all co-owners, and MaPrimeRénov' Copropriété grants significantly reduce each individual's contribution.
For your co-ownership energy renovation, HFE offers Panasonic Aquarea heat pumps installed by an approved ProClub partner: compliant commissioning, optimised manufacturer warranties and long-term technical support.

Any co-ownership registered in the national register, with at least 65% main residences (75% for co-ownerships with more than 20 units), whose building is over 15 years old. Works must achieve at least 35% energy improvement and be supported by an AMO (project management assistant).
Yes. A collective air-to-water or water-to-water heat pump can advantageously replace an ageing oil or gas boiler. It feeds the existing central heating network (radiators, underfloor heating) and can produce domestic hot water. HFE sizes the system for the entire building after a thermal study.
The budget depends on building size, chosen system and existing network condition. With MaPrimeRénov' Copropriété (30–45%), possible bonuses (up to +30%) and CEE, the per-unit out-of-pocket cost can be reduced by 50–75%. HFE provides a free study with a detailed breakdown for the property manager.
The property manager coordinates the project: appointing the AMO, submitting the project for vote at the general meeting, filing the MaPrimeRénov' Copropriété application with the Anah and overseeing the works. HFE works directly with the manager and AMO to simplify the process.
Yes. HFE operates in Lille and within a 50 km radius (Lille metropolitan area, Roubaix, Tourcoing, Villeneuve-d'Ascq, etc.) for collective heating installation and maintenance in co-owned buildings.
