Yes, Milton Keynes has some of the hardest water in the UK and falls in the top 20 locations in the UK for the levels of calcium carbonate the water contains. Supplied by Anglian Water, the reason for the high levels of calcium carbonate is due to the region’s proximity to areas of limestone and chalky rock such as oolitic limestone and cornbrash.

Hard water isn’t an issue for a boiler installation though. 60% of the UK has water that can be categorised as hard and when installing a new boiler in these areas, this is resolved by installing an inexpensive hard water filter at the same time as the boiler. The hard water filter will work to remove any limescale that forms when calcium carbonate in the water is heated and left to stand. To resolve any existing limescale issues in your heating system, we will also undertake a full chemical flush.
