Hard water in Burgundy-Franche-Comté

In Burgundy-Franche-Comté, water hardness ranges from 25 to 45 °fH. This level drives how quickly limescale builds up in pipes, water heaters and appliances. Find the LIMPEO solution that fits your situation.

The right LIMPEO protection for Burgundy-Franche-Comté

The very hard water found in Burgundy-Franche-Comté quickly attacks water heaters, washing machines and pipes. LIMPEO protection becomes essential to avoid breakdowns and energy overcost.

Frequently asked questions — Burgundy-Franche-Comté

What is the water hardness in Burgundy-Franche-Comté?

In Burgundy-Franche-Comté, water hardness ranges from 25 to 45 °fH depending on the water source. The value varies locally — your water bill shows the exact hardness for your municipality.

Why is the water harder in Burgundy-Franche-Comté?

Hardness comes directly from local geology in Burgundy-Franche-Comté. Water flowing through limestone, sedimentary or chalk rocks dissolves calcium and magnesium ions, which form limescale.

How do I know if limescale is affecting my system?

Early signs: visible scale on faucets, white marks on dishes, lower shower pressure, rising water-heater electricity bills. Above 25 °fH, scaling becomes unavoidable without protection.

Do I need a salt softener for very hard water?

No. Salt softeners add sodium to your water (not recommended above 200 mg/L per ANSES) and consume 30–60 kg of salt per year. LIMPEO treats limescale with an electromagnetic field — no salt, no resin — and preserves drinking water quality.

Does LIMPEO really work on very hard water?

Yes. Independent peer-reviewed studies (Trinity College Dublin 2000, Jozef Stefan Institute 2001, MDPI 2024) confirm electromagnetic treatment alters calcium carbonate crystallization, converting calcite (scaling) into aragonite (non-adherent).
