How Water Hardness Affects Your Verossi Boiling Water Tap — And What to Do About It

tristan okulus |

Verossi boiling water taps are transforming modern kitchens across the UK, offering instant hot water, energy efficiency, and sleek design. But there’s one factor many homeowners overlook — water hardness.

If you live in a hard water area, your boiling water tap may be working harder than it should, leading to long-term issues like limescale build up, reduced efficiency, and even component failure. The good news? A few simple steps can help you protect your investment and keep your tap working perfectly for years.


What Is Hard Water, and Do You Have It?

Hard water contains higher levels of calcium and magnesium minerals. When heated, these minerals form limescale, a chalky white deposit that clings to internal components.

Over 60% of UK homes are in hard or very hard water areas. If you live in regions like London, Birmingham, Bristol, or Nottingham, chances are your tap water is on the hard side.

How Hard Water Affects Boiling Water Taps

Boiling water accelerates the process of limescale build up. If left unchecked, hard water can lead to:

  • Internal limescale deposits in the boiler tank

  • Clogged or narrowed pipes and spouts

  • Reduced water flow and performance

  • Noisy or inefficient heating

  • Increased energy use

  • Shorter tap lifespan

It's like the limescale you see in your kettle — but inside a more advanced system, where it's much harder to notice or fix once it's gone too far.


Signs Your Boiling Tap Is Struggling with Hard Water

Not sure if hard water is affecting your tap? Here are some common warning signs:

  • Slower or inconsistent water flow

  • Sputtering or spitting instead of a smooth stream

  • White residue around the tap spout

  • Louder tank noise or unusual humming

  • More frequent filter replacements

  • Heating tank seems slower or less effective

If you're noticing any of these symptoms, it's time to act.


How to Protect Your Verossi Boiling Water Tap from Hard Water

1. Use Hard Water Filters

Our boiling water taps come with a filter — but due to your area, you may need more frequent changes. Make sure you’re using our high-performance filter that can tackle mineral content, not just chlorine or odour.

👉 At Verossi, we offer filters that reduce limescale as well as improve water taste and clarity. If you're unsure which one suits your area, get in touch with us.

2. Regular Descaling Is Essential

A routine descale every 3 to 6 months (depending on your location) can dramatically reduce internal build up.

DIY Descaling Tips:

  • Use a non-corrosive descaler that’s safe for boiling tap systems

  • Avoid vinegar or household acids — they can damage internal parts

  • Follow your manufacturer’s guidelines for safe cleaning

3. Do not Install a Water Softener or Scale Inhibitor

For homes in very hard water areas, adding a water softener or under-sink scale inhibitor sounds like smart long-term solution, but ISNT! Our boiling water systems do not work in conjunction with water softer systems and can lead to further problems.

4. Choose a Tap Designed for Hard Water

Not all boiling water taps are created equal. At Verossi, our systems are engineered to handle UK water conditions — with components built to resist scale and compatible with robust filtration systems.

Our systems have:

  • Limescale-resistant tanks

  • Easy-access filters

  • UK-certified components (KIWA, WRAS, CE)

Final Thoughts

Hard water doesn’t need to be a dealbreaker when it comes to enjoying a stylish, efficient Verossi boiling water tap. With the right setup — a reliable filter, regular maintenance, and maybe a softener — your tap can thrive even in the hardest of regions.
