Power flushing is a process used to clean and maintain central heating systems, particularly those affected by issues like sludge buildup or cold spots. It involves connecting a powerful pump to your heating system and circulating water and cleaning agents at high velocity to remove debris, sludge, and other contaminants. This helps restore heating efficiency, improve circulation, and extend the life of your boiler and radiators. Is there something specific you’d like to know about power flushing?
Power flushing is a thorough cleaning process that removes sludge, rust, and limescale from your central heating system. Using specialist equipment, we flush high-velocity water mixed with powerful cleaning chemicals through your radiators, pipes, and boiler—clearing out blockages and improving heat distribution.
