Hard Water and How Does it Affect Your Boiler?

Limescale and Hard Water

But do you know the difference? Do you know whether you are living in a soft or hard water area? Do you know hard water can affect your appliances or that boilers in certain calcareous water areas are more prone to breakdown? On top of this, you may even be paying significantly higher bills if the water in your area is renowned for limescale. Here we go into more detail about what exactly is hard water and how it affects your boiler.

What Is Hard Water?

Calcareous water contains high levels of calcium and magnesium (higher than 50mg/l). This happens when rich soil and rocks dissolve in water. Although watering plants with scaled water can boost their growth, the same doesn’t apply to your household appliances, such as boilers, washing machines, etc. That’s why you should de-scale them once in a while to prevent the limescale buildups that hard water produces.

What Are the Signs of Limescale?

  • Low Water Pressure – With time, mineral deposits cause blockages in the pipes and narrow down the water flow, which results in low water pressure.
  • Spots – Calcium carbonate deposits can leave spots on silverware and glasses if the H2O in your area is hard.
  • Mineral Stains – The water may make your clothes thin and wear out faster or leave mineral stains.
  • Washing Hands for Longer – Calcium and soap usually create a weird reaction. If you typically have to rinse your hands for a couple of minutes to get rid of soap scrum, that’s almost a surefire sign of limescale.

How Does Limescale Affect Your Boiler and Central Heating System?

Limescale buildups can cause tremendous issues with your central heating system – boiler, pipes and radiators. For instance, limescale buildup can make your boiler heat exchanger lose some of its power and reduce the amount of heat it produces.

On the other hand, it can reduce the flow of gas or hot water through the pipes, affect your boiler’s efficiency (it will push the appliance to work less efficiently and it won’t be able to maintain a consistent temperature). If you don’t get this blockage fixed in time, limescale will cause your boiler to breakdown.

Last but not least, rattling noises in your pipework and boiler are tell-tale signs H2O in your area is scaled and limescale deposits are settling in your central heating system.


As you can tell, calcareous water can cause major damage in the long run. Limescale buildups are harder to remove the longer they sit in your central heating system. To make sure your boiler is running at its maximum and ensure warmth and comfort in your home, have your boiler serviced once a year. This will boost your central heating system’s efficiency and save you a lot of money in the long run. Whether you want your boiler serviced or a new boiler, please don’t hesitate.
