What Is Power Flushing?
Power flushing is a deep cleaning process for your central heating system. We pump a high-flow, low-pressure solution through your radiators, removing:
- Sludge build-up
- Rust and corrosion
- Limescale
- Debris blocking circulation
This restores proper water flow and ensures your system heats evenly and efficiently.
