  • Frequent air blocks in your central heating system
  • Discoloured water coming out when bleeding radiators
  • Uneven heating between the various radiators in your property

There may be other signs you notice too. Talk to us and we can advise you on whether a powerflush is the right approach to take.

How much does a powerflush cost?

The cost of your powerflush will depend on the time it takes to perform. Eight hours is around average, though it can take longer if you have a large property or your heating system is complex. We’ll be happy to give you a quote.

Before a powerflush:

Built-up sediment within the heating system settles at the bottom of radiators, preventing hot water from circulating evenly. This produces cold spots.


After a powerflush:

Sediment has been removed from the heating system, allowing each radiator to work effectively. The addition of corrosion inhibitors ensures long-lasting results.
