Signs you need a powerflush
- Radiators cold at the bottom but warm at the top
- Some radiators not heating at all
- Boiler kettling, banging or making a rumbling noise
- Heating slow to warm up from cold
- Discoloured (black/brown) water when you bleed a radiator
- Repeated boiler breakdowns or expansion vessel failures
How it works — our 4-stage process
- Pre-flush radiator-by-radiator temperature readings logged
- High-flow pump connected; chemical cleaner circulated through the system
- Each radiator individually flushed; magnetic filtration captures debris
- Fresh corrosion inhibitor added and a permanent MagnaClean filter fitted
