Building regulations state that all new or refurbished hot water systems must take provisions to prevent future limescale build up. Water conditioners are becoming the no.1 choice to meet these regulations but with many unreliable, inefficient and costly options Limetron® offers homeowners, contractors and designers peace of mind with a truly reliable and cost effective solution backed by over 40 years experience.

Impact of Limescale

Limescale is caused by the precipitation of calcium carbonate from hard water. Not only is limescale unsightly but it also wastes energy and can lead to equipment breakdown.

Across the world the presence of limescale inside heating equipment contributes to a huge amount of wasted energy contributing to increased co2 emissions.
