Hard Water

The invisible enemy in your home

Hard water is supplied to 60% of UK homes. Whilst causing considerable damage to white goods, fixtures and fittings, it also significantly increases your energy consumption and fuel bills.

Is your home in a hard water area?

Does your home suffer from limescale?

Limescale not only looks horrible but it also acts as a powerful insulating material.

Just 3mm of limescale built-up on your boiler elements and appliances means they will use at least 21% more energy than limescale free elements*, making energy bills substantially higher than they should be. This means that every 1mm of limescale that you leave on your heating elements is wasting 7% more energy than necessary.

If you live in Norfolk, Dorset, Wiltshire, London or any of the other hard water areas, you’re likely to have much more than 3mm on your elements. But there is something you can do…
