Across the UK, water quality varies significantly. Some regions experience soft water, while others deal with hard water, which is well known for causing issues in appliances that heat water. The biggest culprit is limescale, which builds up on heating elements and inside storage tanks, reducing efficiency and lifespan.
For this reason, most boiling tap manufacturers, including Zip, Britvic, and Hyco, recommend or offer optional limescale prevention kits. These kits protect your investment and help keep everything running smoothly.
Why Billi Takes A Different Approach
Unlike other brands, Billi doesn't just suggest a limescale prevention kit - they make it mandatory. Whether you live in a hard water area or not, Bili insists on installing a limescale filter alongside every boiling tap.
Their reasoning is straightforward: all water heaters are at risk of scale build-up, even in regions with softwater. Tiny mineral particles in the water can affect sensitive components like heat and level sensors. By requiring filtration, BIlli ensures their systems stay reliable and efficient. They also protect themselves from warranty claims caused by poor water quality, as installations without a filter may not be covered.
The Billi Everpure Claris Filter System
At the heart of Billi's protection strategy is the Everpure Claris filter range. These filters do more than reduce limescale. They also balance pH levels to prevent corrosion and use a five-stage filtration process to deliver high-quality water consistently.
What sets Billi apart is the versatility of their range. Whether you need a compact filter for a low-use domestic tap or a high-capacity sstem for commercial settings, there's a Claris filter to match. With five different size options available, Billi makes sure every installation gets the right level of protection.
The Bottom Line
Billi's strict stance on filtration may add an upfront cost, but it's a policy based on long-term reliability. By insisting on limescale prevention, they help customers avoid performance issues, costly repairs, and unnecessary downtime.
