It often indicates sludge or debris restricting water flow, although trapped air, balancing issues or a faulty valve can cause similar symptoms. Identifying the cause early can prevent wasted energy and uncomfortable rooms. What

Central heating systems in the UK work hard for much of the year. Over time, corrosion, magnetite, sludge and limescale can collect inside radiators and pipework. This can reduce circulation, create noise and make your boiler work harder. Understanding how often a central heating system should be flushed can help homeowners protect comfort and efficiency.

Sludge inside a central heating system can affect more than radiator temperature. It may restrict circulation, cause noise and place additional demand on the boiler and pump. For UK households trying to control energy use, maintaining clean system water is an important part of wider heating efficiency. What is heating sludge? Heating sludge is a
