Why Does My Central Heating Need Power Flushing or a Descale?

Rust occurs in all central heating systems producing a black (iron oxide) sludge and, in hard water areas, lime scale builds up in combination boilers just like in your kettle causing the following problems:


Black sludge in the radiator when bleeding

Dirty black or brown water present when bleeding radiators confirms system corrosion.

 Radiators cold at bottom from trapped black sludge. Remove sludge by powerflushing

Radiators cold at bottom due to black sludge.
Radiators cold all over due to blocked valves and pipes. Powerflush to unblock

Radiators cold all over due to blocked valves and pipes.

 Irritating boiler noise from lime scale and sludge build up, a warning sign of imminent costly problems. avoid with a power flush

Irritating boiler noise from sludge or lime scale build up, a warning sign of imminent costly problems.
No hot water due to blocked pipes and heat exchangers. unblock with a powerflush

Little or no hot water due to blocked pipes and heat exchangers.

 Boiler cutting out and no circulation due to blocked pump or heat exchanger. Unblock your pump by powerflushing

Radiators cold at top due to trapped gas, a by product of system rust.

Radiators cold at top and need bleeding due to gases, a by product of rusting.
