Combination boilers

Combination boilers are particularly susceptible to limescale, it causes poor water flow and noise/kettling – it is strongly recommended in hard water areas that a scale inhibitor is fitted.
Because there is not any stored water with a combi system the beneficial effects of fitting Scale Manager will start almost immediately.

Scale Manager will not …

Scale Manager will not alter the taste of water.

It will not remove all Limescale from your kettle, steam iron or appliances that heat water beyond 92°C.

This is because when the temperature of treated water rises above 92°C the water will start to revert back to its pre-treated form, therefore some limescale may still appear in appliances that take the water to very high temperatures. However, you should experience a 60-80% improvement. It is also beneficial to empty such appliances each time after use.

Scale Manager will not cover central heating plumbing because it is a separate circuit. Limescale treatment is
normally unnecessary as the same water is continually circulated; unlike the rest of your plumbing where continual new supplies of limescale forming calcium carbonate are being introduced.
