Whole House Water Treatment
Hard water affects every corner of your home, from the kitchen sink to the shower, from the washing machine to the boiler. LIMPEO whole house water treatment installs on the main water inlet and delivers anti-scale protection to every outlet. One device, total coverage, zero chemicals.
Key benefits for your home
Why whole house water treatment matters
Limescale is the silent enemy of domestic plumbing. In regions where water hardness exceeds 20 French degrees, calcium carbonate deposits accumulate rapidly inside pipes, reducing flow rates and increasing pressure. A whole house anti-scale treatment at the main inlet tackles the problem at the source. LIMPEO's electromagnetic field converts dissolved calcite into aragonite micro-crystals that stay in suspension rather than adhering to surfaces. Independent tests at the University of Toulouse confirmed an 88% reduction in hard deposits. Instead of treating each appliance separately, a single LIMPEO device on the main pipe protects every water outlet in the house, from garden taps to bathroom showers, delivering consistent anti-scale performance throughout.
How LIMPEO protects the whole house
The LIMPEO device wraps around the main water supply pipe, right after the meter. Its patented electromagnetic signal propagates through the entire plumbing network. As water flows through the treated section, dissolved calcium ions crystallise into aragonite rather than calcite. Aragonite crystals are rounded, non-adhesive, and flow harmlessly to the drain. This means every downstream fixture benefits: taps stay clean, shower screens remain clear, and heating elements stay efficient. Installation takes under thirty minutes with no pipe cutting, no bypass, and no electricity other than the unit's low 5-watt consumption. The whole house water treatment system works on copper, PVC, PER, and multilayer piping without restriction.
Energy and financial savings
Scale build-up on heating elements is a proven energy drain: each millimetre of limescale adds approximately 7% to energy consumption. For a typical four-bedroom house with a 200-litre water heater, that can translate to over 150 EUR in wasted electricity per year. By preventing scale at the main inlet, LIMPEO whole house water treatment keeps every heating element at peak efficiency. Boiler servicing intervals stretch further, plumbing repairs decrease, and appliance lifespans extend by 30 to 50 percent. Detergent and cleaning product use drops because soft-feeling water lathers more effectively. Across a ten-year period, a household typically saves several times the initial investment, making LIMPEO one of the most cost-effective anti-scale solutions available.
Choosing the right LIMPEO model
For a standard single-family house with a main pipe diameter of 20 to 28 mm, the LIMPEO J-250 or J-320 is the recommended whole house water treatment choice. The J-250 covers pipes up to 25 mm and suits homes up to 120 square metres. The J-320 handles pipes up to 32 mm and is ideal for larger properties with multiple bathrooms. Both models are silent, maintenance-free, and designed for a 20-year lifespan. If your house has a garden irrigation loop or a detached outbuilding, we recommend the J-320 to ensure the electromagnetic signal reaches every branch.
