How hard water can affect my heating system?

Tuesday 27th April 2021

Soft water has a low content of calcium carbonate, magnesium, and other minerals. Hard water contains a high amount of these substances. The large majority of homes in England have a hard water system. It's fine to drink water with a high mineral content, but it's not the best water for a heating system.

How might hard water affect my heating?

Calcium and magnesium turn into hard deposits of limescale. These cause damage to the water system because they cause blockages. When your heating system is full of limescale your system has to work harder to heat your property. The result is often that the system overheats and eventually breaks down. At first, you might notice that your water doesn't get very hot, or that the pressure is low.

Hard water causes various problems including:

• Your home will be less energy efficient.
• Your bills will be more expensive.
• Your property may be too cold.
• The water pressure may be too low.

How can I improve my heating system?

To improve your heating system, use a limescale remover to descale your boiler. If you're still having issues it's best to call in the experts. Heating engineers can provide many different solutions, to remove hard water from your heating system. To remove limescale from your radiators and pipes, you may require a 'power flush'. The solution works by flushing a mixture of water and chemicals through your heating system.
