Limescale build up in Milton Keynes toilet which was repaired by the plumbers at Lime Heating

The hidden cost of hard water on Milton Keynes homes

If you live in Milton Keynes or the surrounding areas, you’re living in one of the UK’s hardest water regions. You might be waging war on the limescale on your taps and in your kettle but that’s not the whole picture. The thing that’s keeping the plumbers of Milton Keynes awake at night is the hard water that’s silently damaging your heating and plumbing system.

Over time, this build-up of minerals leads to higher bills, unreliable heating, and expensive breakdowns. In this in-depth guide, we’ll explain:

  • What hard water is and why it’s a problem
  • The real impact of limescale on your heating system
  • Ways hard water could cost you more
  • Proven solutions to protect your home
  • Why prevention is always cheaper than cure

At Lime Heating, we’re experts in helping Milton Keynes homeowners tackle hard water and look after their heating system. Here’s everything you need to know.

What is hard water?

Water is classed as “hard” when it contains high levels of minerals like calcium and magnesium. While perfectly safe to drink, once heated in your kettle, boiler, or radiators, these minerals transform into limescale. That chalky build-up doesn’t just look unsightly – it can also take a toll on your appliances.

We bet you’ve picked up at least one product (possibly a cupboard full?) for your bathroom or kitchen on the promise that it’ll beat limescale… But what about your plumbing, boiler and heating system? That same build-up is forming inside your boiler’s heat exchanger and clogging up your pipework and pumps. Left unchecked, it can lead to serious efficiency and reliability problems.

How hard water damages your plumbing

Hard water causes more than just surface-level scale. It creates multiple issues inside your heating system and plumbing:

  • Reduced boiler efficiency: even a small build-up of limescale on your boiler’s heat exchanger can effect heat transfer and reduce efficiency.  That means your boiler works harder and burns more gas to heat the same amount of water
  • Restricted water flow: limescale can clog taps, showers and sanitary ware, restricting water flow, looking unsightly and reducing function 
  • Increased breakdowns: limescale clogs up pumps, valves and pipes. These blockages cause numerous problems, often requiring costly repairs
  • Damage to immersion heaters: hard water causes limescale to coat the element, essentially acting as a layer of insulation. This forces the element to work harder, reducing efficiency and is a frequent cause of failure
  • Clogged hot water cylinders: limescale build-up inside the cylinder will eventually reduce hot water capacity. It also slows down heat transfer, again affecting efficiency and increasing cost
  • Shorter system lifespan: a boiler that should last 12–15 years may fail years earlier if limescale is severe and left untreated

How to protect your plumbing

The good news? There are several proven solutions to keep your system running smoothly. At Lime Heating, we recommend a combination of these depending on your home, budget and condition of your system:

 

Water softeners

Installed at the mains, they treat all the water entering your home. This reduces limescale at the source. An effective option but expensive, so not for everyone

 

Scale reducers

A small, in-line device fitted to the cold water supply. Slows limescale build-up, helping protect your boiler and appliances and improve efficiency. More cost-effective than a water softener

 

Regular servicing

Annual servicing helps spot early signs of limescale and ensures filters and inhibitors are topped up. The easiest and most budget-friendly option for maintaining your system

Why prevention is better than cure

Milton Keynes is in one of the UK’s hardest water regions. This means the risk of limescale is much higher than average. It helps to know that it’s always cheaper to prevent limescale than to fix the damage afterwards. With the right system care, you’ll:

  • Keep your energy bills lower
  • Reduce expensive repair callouts
  • Extend the life of your boiler, taps, showers and more
  • Enjoy a warmer, more reliable home
