the problem identified

Limescale on the surfaces of pipes, heat exchangers and other water system components have significant implications for energy efficiency, system performance and plant integrity.

limescale

Limescale in hard water areas has been a problem since people first started heating water and now makes a major contribution to the running costs of heating and hot water systems used in both building services and industrial applications. In the UK alone the cost of limescale formation to industry is estimated at over £1bn per annum and the cost to the environment through wasting energy is equally significant.

Studies have shown that a 25mm thick layer of limescale on a heat exchange surface will reduce heat transfer by 95% and this has implications for energy costs. Just a 1mm layer of limescale will increase energy costs by 7.5%, while a 12mm layer will raise this increase to 70%.

Limescale has the potential to impair performance at many points in a water system:

• Inefficient heat transfer on heat exchange surfaces
• Blocked pipes leading to early replacement
• Seized valves
• Blocked showerheads
• Unsightly deposits
