Where We Reveal Some Hard Facts About Hard Water

Many thanks for visiting our site. Lets dive straight in and reveal a scary fact – did you know that limescale in your home’s pipework, showerheads, basin taps and kitchen fittings is the perfect breeding ground for micro-organisms such as bacteria and fungi. The rough surface of limescale allows bacteria to adhere to and thrive, as well as providing a mineral rich food source.

Your goal should be to reduce limescale build-up throughout your whole home. But how do you reduce the accumulation of limescale caused by the minerals in hard water? Is the high cost of a water conditioner a worthwhile investment for you? Do they actually work and where’s the proof? Lets see if we can answer these and other vital questions for you below.

We have scoured the web for all the latest information on hard water conditioners in the UK and how they can improve the health of your domestic plumbing system. We have focused on chemical and salt free units that are zero maintenance and claim to reduce limescale accumulation and inhibit corrosion. Read on to learn how a water conditioner works and why only a good quality (i.e. expensive) water conditioner will drastically reduce scale build-up, which in turn translates to energy savings and less maintenance costs on boiler and kitchen appliance breakdowns.

The Best Solution For Limescale Reduction

What Are Water Conditioners?

Water conditioners provide an eco-friendly, salt-free and chemical-free solution to tackling hard water problems without the need for ongoing maintenance. Unlike traditional water softeners that require regular salt top-ups, water conditioners work silently in the background, reducing limescale build-up while preserving the natural healthy minerals in your drinking water. The end result: healthier appliances in your kitchen and healthier bones in your body.

By transforming the structure of hard water minerals, water conditioners stops them from sticking to surfaces in your pipes, boilers, shower heads, and appliances, helping to extend their lifespan and improve efficiency. This means you get the limescale-protection benefits of a water softener without the hassle of refilling salt, messy clean-ups or dealing with a complex system that requires regular servicing.

Did you know? Every 1mm of limescale on any heating element adds 7-10% to it’s energy consumption (according to British Water). This can increase energy costs by up to £200 per year! Water conditioners help your heating system run more efficiently by preventing limescale deposits, saving you money and reducing your carbon footprint in the process.

Do You Live In A Hard Water Area Of The UK?

Why Should I Use A Water Conditioner?

There are chalk and limestone regions scattered through the UK, especially in the South and East of England. An estimated 17 million UK homes are in hard water regions. The more limescale deposits allowed to build-up within your pipes, boiler heat exchanger and kitchen appliances, the more reduced water flow issues and appliance breakdowns you will experience. This can lead to long downtimes, expensive repairs, and in some cases total replacement.

Integrating a inline water conditioner into your mains water supply is a great way to reduce the amount of mineral build-up in your plumbing, as well as offering protection from metal corrosion which can occur beneath the scale.

Do Water Conditioners Actually Work?

There’s a lot of debate around water conditioners, but the truth is that some work better than others. The Aquabion S15 & S20 are proven products, with extensive manufacturer data available, including test results that demonstrate their effectiveness.

If you’re looking for independent studies, the University of Surrey conducted research on the Advanced Hydro ACP (Advanced Crystallisation Process) technology, which showed great success in limescale control. Similarly, Halcyan Water Conditioners have been independently tested and verified to effectively prevent and reduce limescale buildup.

View Proof View Summary

This independent testing and evaluation report concludes…

…prevents over 80% of scale formation…
…represents in excess of a 5 fold reduction in scale build up…

So, do water conditioners work? Yes – when you choose the right type of technology and ignore unproven claims made by magnetic/electro-magnetic/coil-wrap type gimmick “water conditioners”. And unlike traditional salt-based water softeners, the Aquabion, Halcyan and ACP units mentioned here do not remove beneficial minerals, require zero maintenance, and last for up to 30 years – making them a true fit-and-forget solution.

Struggling To Heat Your Home?

Graph of energy wastage due to limescale

Reduce Your Energy Bills

Many studies have proven the negative effects of limescale on your heating system, causing your boiler to burn more energy to deliver the same amount of output.

The Carbon Trust noted a 7% increase in energy usage for a 1mm layer of limescale. British Water calculated a 12% loss in heating efficiency for every 1.6mm of limescale build-up in your heating system.

This equates to an average of £200 added to your energy bill every year. And if you are in a hard water area you could be looking at a 6mm build-up of scale over four years, a massive 40% hit on energy costs.
