A power flush is a cleaning process for your central heating system that removes built-up sludge, rust, and debris from radiators, pipes, and the boiler.
A machine is connected to your system and pumps water with special chemicals through at high pressure.
This dislodges and flushes out sludge, corrosion, and scale that block pipes and reduce heat output.
Cold spots on radiators (especially the bottom)
Radiators slow to heat up
Dirty water when bleeding radiators
Boiler keeps shutting off or error codes appear
