Living in Kent, our hard water supply is a common culprit for heating system issues. Over time, limescale builds up inside your boiler and pipework, which can restrict flow and cause internal components like heat exchangers to overheat or fail. If you notice your boiler making strange kettling noises or taking longer to heat your radiators, it may be struggling with limescale. During my emergency visits, I often help residents deal with these hard water effects by clearing blockages, replacing faulty pumps, or advising on limescale prevention. I also frequently assist with winter-specific issues, such as frozen condensate pipes that stop your boiler from firing during a cold snap.
