There has been a lot of debate lately about how much households are spending on energy, amid rising prices. And with the winter of 2021 on the horizon, it is fair to say that many families – in London, the South East and beyond – are feeling the need to crank up their heating in order to feel comfortable. 

We’ve previously written about various ways you can minimise your own energy bills – but could there be a culprit for escalating costs that you haven’t even stopped to consider? 

That potential enemy, as cited by one recent article in the Express, is limescale. 

What is limescale, anyway? 

The term “limescale” refers to a substance largely made up of calcium and magnesium, which forms with the evaporation of hard water. If you’ve ever spotted a hard, chalky deposit in areas of your home where water is typically heated or left standing – such as on taps and shower heads – the chances are that you are looking at limescale. 

With limescale also prone to developing in less visible parts of a property – such as in radiators and the inner surfaces of pipes – it really is a potentially big problem that you might not even notice in your abode until it starts doing serious damage. 

Limescale comes about due to hard water, which in turn, arises as a consequence of the minerals that enter the water as it passes through chalk and limestone regions, such as those in the south and east of the UK.  

The connection between limescale build-up and higher bills 

The good news is that hard water doesn’t generally pose a health risk. It can, however, spell bad news for your energy expenditure, as the accumulation of limescale means that more energy has to be used in order to run the typical home’s plumbing equipment and other appliances. 

The Express article cited research by the Water Quality Research Foundation, which discovered that it costs about 29% more to heat untreated water. 

If limescale build-up in your home is not addressed, there may also be a greater likelihood of your plumbing equipment malfunctioning or sustaining damage. 

What steps can you take now to help combat limescale in your property? 

Fortunately, it doesn’t necessarily need to be that arduous a task to keep limescale build-up in your home at bay. Simply taking the time to clean certain household items and appliances can go a long way to removing limescale, and lowering your energy bills as a result. 

To this end, our Sunbury, Beckenham and Dorking plumbers would urge you to keep an especially close eye on your kettle, washing machine, iron, dishwasher, taps and shower heads. 

However, it is also crucial to do everything you can to protect your boiler’s health. Ask most Kingston, Guildford and Dorking plumbers, and they would tell you that hard water and the accumulation of limescale can be a major threat to your boiler’s trouble-free operation. Getting your boiler checked by a professional at least once a year will therefore help put your mind at rest. 

Don’t forget that simply skipping a boiler service and thinking “it’ll be fine” could run the risk of your boiler breaking down unexpectedly, which might cost you hundreds of pounds to fix. That’s the very last thing you will want during the colder months – so, please don’t hesitate to contact our plumbers and heating engineers for free advice and a competitive quote.
