Aquabion H20 3/4 Inch Galvanic Water Conditioner Salt Free Limescale Reducer DN20
Aquabion H20 3/4" Water Conditioner — Compact galvanic limescale & corrosion protector for homes & small businesses | No salt, no electricity, no chemicals, no maintenance | Flow up to 2.5 m³/h | Threaded DN20 connection | 7-year life expectancy | DVGW-certified & patented technology | Ideal for single-family houses, flats, small shops or offices with moderate water usage
Installs inline after the stopcock or meter on metal or plastic pipes (with equipotential bonding). Protects boilers, cylinders, showers, taps & appliances. Replace unit after 7 years — zero ongoing costs or servicing.
The Aquabion H20 is the smallest and most popular model in the Aquabion galvanic range — specifically sized for typical domestic and small commercial properties in the UK where incoming mains flow is moderate (up to 2.5 m³/h) and limescale protection is needed without the expense, sodium addition or maintenance of traditional salt softeners.
It uses the same patented zinc galvanic anode technology as larger models: controlled zinc ions are released into the water flow, altering calcium carbonate crystals from hard, adherent calcite into soft, non-sticking aragonite. Scale no longer builds up inside pipes, boilers, heat exchangers, showers or appliances — reducing energy bills, extending equipment life and maintaining water pressure — all while keeping the natural hardness minerals in the water (no sodium added, safe for low-sodium diets).
The stainless steel body with 3/4" female threaded connections is compact (only 260 mm long), robust (16 bar rated) and features internal stainless swirling elements to ensure effective galvanic action. The zinc anode is consumed over time — simply replace the entire unit after 7 years (no refills, no cleaning). DVGW-certified for potable water safety and trusted across Europe for reliable, zero-maintenance performance.
What Makes the Aquabion H20 Special?
- Salt-Free & Eco-Friendly — No sodium, no brine discharge, no environmental impact — perfect for drinking water & eco-conscious homes.
- Zero Running Costs — No electricity, no salt bags, no regeneration — truly maintenance-free for 7 years.
- Patented Galvanic Protection — Converts limescale to non-adherent form — proven to reduce scale & protect against corrosion (DVGW W270 compliant).
- Compact Domestic Size — Fits easily under sinks, in cupboards or next to meters — ideal for UK properties with 15–22 mm mains.
- Protects Whole House — Safeguards boilers, cylinders, showers, washing machines, dishwashers & pipework from scale damage.
- DVGW Certified & Recyclable — Meets strict European potable standards; unit fully recyclable at end of life.
