Power Flushing Services
Power Flushing in Hull & Surrounding Areas
Restore your heating system’s performance with a professional power flush from FlowMarsters Plumbing & Heating.
A power flush improves efficiency, removes sludge and restores proper circulation — helping your home heat up faster and reducing your gas bills.
What Is a Power Flush?
Over time, heating systems build up sludge, rust and debris inside pipework and radiators.
This causes:
- Cold spots on radiators
- Slow heat-up times
- Noisy boiler or pump
- Poor circulation
- Higher energy bills
- Frequent breakdowns
A power flush uses specialised equipment and powerful cleaning chemicals to completely clear out the system and restore proper flow.
Signs You Need a Power Flush
You may benefit from a power flush if you notice:
- Radiators cold at bottom or sides
- Some radiators not heating at all
- Boiler kettling or banging noises
- Black or dark brown radiator water
- Radiators take ages to warm up
- Pump repeatedly failing
- Boiler keeps shutting down
- System constantly getting air in it
If you’re unsure, we can assess your system and advise honestly.
