Power Flush vs Bleeding Radiators
Many homeowners wonder whether they need a power flush or simply need to bleed their radiators.
Bleeding Radiators
Best when:
- Top of radiator is cold
- Air trapped inside system
- Individual radiator affected
Power Flushing
Best when:
- Bottom of radiator is cold
- Multiple radiators affected
- Sludge or magnetite present
- Boiler performance declining
- System is ageing
If you’re unsure, our engineers can assess your heating system and recommend the most cost-effective solution.
Talk to Our SpecialistsHow Often Should You Power Flush Central Heating?
Most heating systems benefit from a professional power flush every 5 to 6 years. However, the right frequency depends on the age of your system, water quality and how well it has been maintained.
You may need a power flush sooner if:
- Radiators develop cold spots
- Boiler efficiency drops
- Corrosion is present
- Heating becomes uneven
Regular boiler servicing and inhibitor top-ups can help reduce sludge build-up between flushes.
