It involves connecting a machine to the central heating system, usually at the central heating pump or magnetic filter. Dirty water is then flushed from the system and it replaced with clean water. Special chemicals are added, heated up and circulated to remove residual debris. The radiators are then isolated, and each radiator is flushed separately. When the last radiator has been flushed, the water is discarded and replaced with clean water.

You can check for 'cold spots' on your radiators. If they are cold at the bottom and hot at the top you may have a build-up of debris. This is when you need a Power Flush to prevent blockages in radiators and pipework. For newer boilers, if the system is not well maintained this can invalidate the manufacturer's warranty.
When traditional, heat-only boilers or those with old pipework take longer to heat up, this can be a sign of dirt and debris building up. Also, heating systems with microbore pipework can become blocked quicker with only a small amount of debris. In all these instances, a Power Flush is recommended and will inevitably rectify the problems.
