Hard water in the Lille metropolitan area means scale on taps, water heaters and appliances. Hecker & Frères Énergie (HFE) sizes and installs the right softener for your water, your system and your goals — salt, SoluCalc® CO₂ or DRAGO.
Each technology meets a different need. We advise you after analysing your water and visiting your property — without pushing a one-size-fits-all solution.
The most common anti-limescale solution: ion exchange for softened water and durable protection of your pipework and equipment.
Our preferred eco-friendly anti-limescale solution: no salt, no brine discharge, minerals preserved.
Physical/electronic treatment that changes how limescale behaves without removing it from water — discreet, no salt and no electricity.
For CO₂ treatment, Hecker & Frères Énergie (HFE) mainly works with SoluCalc®, an ecological salt-free water softener. The technology converts limescale into soluble bicarbonate that no longer builds up in pipework, taps and appliances — no sodium, no regeneration wastewater and low maintenance (CO₂ refill roughly once a year).
An alternative to salt softeners: no heavy salt bags and no salty wastewater into the drain.
Calcium and magnesium remain in the water for taste and mineral balance.
Discreet system after the water meter, suitable for homes across the Lille metropolitan area.
Less scale on boilers, washing machines, dishwashers and sanitary pipework — energy and cleaning product savings.
We size and install SoluCalc after analysing your water and installation. Salt or Drago remain options when your situation requires them — we advise you during the on-site survey.
