A power flush is a thorough cleaning process for a heating system that helps remove sludge, rust, and other debris that build up in radiators and pipework over time. During the procedure, a powerful, high-flow pump is connected to the heating system, pushing a chemical cleaning solution through the pipes and radiators at high velocity.

This dislodges and flushes out the accumulated contaminants that can cause blockages, cold spots on radiators, and reduced heating efficiency. Once the debris is expelled, the system is flushed with clean water, and an inhibitor is added to help prevent future corrosion. This process restores optimal performance, improves heat distribution, and can prolong the life of the boiler and heating system.
