Does a Kettle with Limescale Use More Electricity?

It is no secret that limescale can have a negative impact on the performance of your kettle. But did you know that limescale can also increase your electricity bills? In this blog post, we will explore the effects of limescale on your kettle’s electricity usage and how to reduce it.


What is Limescale?

Limescale is a hard, chalky deposit that builds up inside kettles over time due to the presence of calcium and magnesium in hard water. This build-up of limescale can reduce the efficiency of your kettle and cause it to use more electricity than usual.


How Does Limescale Affect Electricity Usage?

When limescale builds up inside a kettle, it acts as an insulator, trapping heat and preventing it from transferring to the water. This means that more energy is required to heat the water, resulting in higher electricity bills. So, every cup of tea you make costs that little bit more which, over time, can make a big difference to your bills.


How Can You Reduce Limescale Build-Up?

Fortunately, there are several steps you can take to reduce limescale build-up in your kettle and keep your electricity bills as low as possible:

Use bottled water: Using filtered or bottled water instead of tap water will help reduce limescale build-up as these types of water contain fewer minerals than tap water.


Boil only what you need: Boiling more water than necessary wastes energy and increases electricity bills unnecessarily – so only boil as much as you need!


Clean regularly: Regularly cleaning your kettle with vinegar or citric acid will help remove any existing limescale deposits and prevent new ones from forming.


Use de-scaler: If you find that regular cleaning isn’t enough to remove all the limescale from your kettle, then you may want to consider using a de-scaler product specifically designed for kettles. These products are usually effective at removing stubborn deposits of limescale.


Banish limescale for good: Installing a water softener or water conditioner reduces limescale build-up in the home so your limescale issues become a thing of the past.
