Powerflush in London
Over time, sludge builds up in radiators, causing cold spots and reducing efficiency. A powerflush restores your heating system’s performance and extends its life.
A powerful flow of water and cleaning chemicals flushes debris from pipes and radiators, clearing blockages and leaving your system running smoothly. We finish by adding inhibitor to protect the system.
A powerflush is often required by boiler manufacturers before a new boiler is fitted to an existing system.
