There are two main methods of flushing a central heating system - Powerflush, and manual flushing. Each has its own process, which we will walk you through in this section.
Powerflush is the process of using a specialised device to pump cleaning chemicals into your system, circulating them and removing the unwanted material from the system itself. The chemicals are pumped at a high pressure to ensure any rust, corrosion, sludge, or miscellaneous debris is effectively removed.
Generally, a Powerflush will take around 8 hours to complete fully, though a portion of this time is dedicated to the system pumping around the entire central heating loop. Particularly large or complex heating arrangements can take much longer to complete.
We do not recommend users to Powerflush a system, as it requires the use of specific chemicals for the job and a dedicated machine to do so. As this requires additional knowledge about your heating system, as well as complications from varying types of systems, this is best tackled by a trained heating engineer.
