Limescale Reducers for Boilers

What Are Limescale Reducers & Should I Fit One?

Did you know that 60% of UK properties are affected in some way by limescale? Living in a hard water areas such as Hertfordshire, London and the South East can be a real problem! Particularly for your boiler. This article explores the use and benefits of limescale reducers for boilers.

Reduced Energy Efficiency

effects-of-no-limescale-reducers-on-heating-elementsIf precautions are not taken lime scale can greatly reduce the energy efficiency of your central heating and hot water system, with appliances at risk of scale damage, especially when it heats up.

Water containing 145 ppm of calcite, flowing at 3.5 litres per minute, produces in one year 4.8 kilograms of scale at 60ºc. At 80ºC this rises dramatically to 29.9 kilograms!

Generally, this affects central heating systems, hot water systems, washing machines, dishwashersshowers and bathroom taps which can be costly to repair or indeed replace. With the cost of energy, gas and electric bills have gone up hundreds of pounds since 2010, so it’s worth understanding that just 9 grams of limescale reduces a boilers efficiency by at least 5.6%.

Research indicates that modern high efficiency boilers work at higher temperatures than standard boilers. With high efficiency boilers, temperatures flfluctuate more, waterways tend to be narrower and heat exchangers thinner so that lime scale build up has a more serious effect on performance, often resulting in boiler breakdown.

Putting the correct solution in place can save you lots of money on energy and on repair bills.

So what are the benefits of Limescale Reducers?

  • It will reduce your energy bills
  • It will give your appliances, central heating system, pipe work and taps longer life and guarantees and  much better efficiency.
  • There is little or no maintenance once a scale reducer has been installed
  • Economical little to no running costs
  • Environmentally friendly
  • Quick and easy to install
  • Complies with Part L Buildings regulations


We strongly recommend that you fit a limescale reducer to your hot and cold water appliances around the home. If you live in or out of London the benefits far outweigh the small cost of lime scale prevention.
