Enjoy fresh drinking water without impurities, protect your heating system and prolong the life of household appliances with this high quality limescale inhibitor from the experts at NoCalc.

Did you know that 1mm of limescale on a heating element means it uses 8-9% more energy? The NoCalc limescale inhibitor adds a small quantity of consumable solution into your water supply which neutralises—but crucially, does not remove— calcium and magnesium, preventing limescale from forming.

As well as improving the efficiency of your heating, NoCalc also prolongs the life of your household appliances like dishwashers, washing machines, kettles and more. Your water remains 100% safe to drink with an improved taste, conforming to British Standard BS EN 1212.

Quick and easy to install, this limescale inhibitor doesn't require an electrical connection to operate and comes complete with all the fixings and wall brackets you'll need. WRAS (Water Regulations Advisory Scheme) approved, it comes complete with a long life cartridge that lasts for up to 40,000 litres (between 3–6 months in an average household). They are easy to change and an optional, audible signal tells you when a change is required. This product is ideal for homes in hard water areas.
