Come to Stand B28 and see the HALCYAN whole-house unit for yourself. It's small, it's mighty, and it protects your entire home from limescale without salt, electricity or wasted water.

You're choosing beautiful taps, glass screens, stone and tiles. Limescale, and the cleaning chemicals you need to deal with it, is the invisible enemy of every one of them. It affects around 60% of UK homes, and building regulations require scale treatment in hard water areas. So if you're building or renovating, this is a decision you'll live with for decades. It's worth seeing every option before you make it.

HALCYAN is a passive water conditioner that fits on your incoming mains, near the stoptap. It prevents new limescale forming and removes existing scale. Your hard water then behaves like soft water, protecting the finishes you've chosen along with your showers, appliances, hot water system and plumbing throughout the home. Nothing to top up, nothing to plug in, nothing flushed down the drain. Because the minerals stay in, the water stays drinkable from every tap in the house.

See it live – then take your time. Pick up the unit and see just how compact whole-house protection can be. No survey is needed. Our exclusive show discount runs for three weeks after the show, so you can go home, think it over and decide without pressure.

Bring your questions – all of them. Our team brings over 40 years' experience across domestic and commercial water systems. We'll give you straight answers: how HALCYAN works, what it costs over its lifetime, how it compares with the other options on the show floor, and when it isn't the right choice for your home.
