Warning signs in W2

Signs your system needs a power flush

Cold radiator bottoms

Magnetite sludge settles at the bottom of radiators, blocking water flow. The bottom stays cold while the top gets hot. London's hard water creates this problem faster than soft-water areas — most London systems need a power flush after 8-12 years without treatment.

Noisy boiler (kettling)

A banging or rumbling boiler is caused by limescale on the heat exchanger restricting water flow and creating hot spots. A power flush removes the loose scale; a descale chemical treatment targets hardened deposits. Post-flush, the boiler should run quietly and efficiently.

Slow heat-up and high bills

A heavily sludged system can reduce heating efficiency by 15-25%, meaning your boiler burns more gas to achieve the same temperature. Most customers see measurable improvement in heat-up time and reduced gas consumption after a power flush.

Maintenance interval: after a power flush we recommend fitting a magnetic filter (Adey MagnaClean or Fernox TF1) to capture particles before they resettle. With a filter fitted and inhibitor topped up annually, most London systems won't need another power flush for 10+ years.

What we do in W2

Power flush process checklist

Pre-flush system assessment — checking radiator temperatures, boiler efficiency, sludge levels
Connecting power flush machine — high-velocity pump attached to central heating circuit
Chemical treatment — descaler, sludge remover and corrosion inhibitor introduced
Direction reversal flushing — reversing flow to dislodge stubborn deposits
Individual radiator flushing — connecting to each radiator for focused cleaning
Boiler heat exchanger flush — targeting the most critical component
Drain and refill — removing all contaminated water from the system
Fresh inhibitor dosing — Fernox F1 or equivalent for long-term protection
Magnetic filter installation — Adey MagnaClean or Fernox TF1 to capture future particles
Post-flush efficiency test — measuring radiator temperatures before and after
Boiler flue gas analysis — confirming improved combustion efficiency
Written report — documenting condition before and after, inhibitor concentration
