Halcyan Water Conditioner

The Ultimate Limescale Solution From Halcyan - With A Lifetime Warranty!

If you live in a hard water area of the UK, you should consider installing one of these WRAS-approved devices to reduce limescale build-up and corrosion in your home's central heating system, pipework, and appliances.

We have teamed up with Halcyan to promote their market-leading H2o9 and H2o18 domestic water conditioner units, both offering a comprehensive 30-year manufacturer's warranty. These revolutionary devices easily outperform the Aquabion S15 and S20 water conditioners, which offer a mere 5-year warranty.

H2o9 - 'Favourite' Whole House Water Conditioner

This unit is the ideal solution for most UK households. With an easy inline installation that takes less than an hour and zero maintenance, you will quickly notice a decrease in hard-to-clean limescale.

The H2o9 also eliminates existing limescale build-up over time, effectively descaling your boiler and appliances and cutting energy costs by up to £500 per year. It's an eco-friendly alternative to salt-based softeners, lasting more than 30 years with zero upkeep. Enjoy the benefits of softer-feeling water while reducing your carbon footprint.

Available for 15mm or 22mm incoming mains pipework.

Please note that we will receive a small commission on any sale without affecting the price you pay.

H2o18 - 'Castle' Whole House Water Conditioner

The H2o18 premium water conditioner, designed for larger homes and properties with high water usage, offers unmatched protection against limescale while promoting energy efficiency and sustainability. This 22mm unit is capable of supplying multiple showers and appliances running at the same time.

Before ordering, we recommend you work through the Halcyan Sizing Tool to determine the most effective solution for your requirements.

Their advanced conditioning technology transforms hard water minerals into a harmless non-adhering powder rather than a “sticky" scale that coats all internal metal surfaces. This is where cutting-edge technology meets sustainability, safeguarding your home for decades to come.
