Powerflush
A power flush is a procedure that removes sludge and debris from your heating system and boiler using a specialised machine and chemicals. If sludge and other harmful substances are allowed to build up, they can prevent your heating from functioning properly and cause damage to your boiler and system. For a standard-sized property, a power flush typically takes around 6-8 hours, depending on the number of radiators you have. We also recommend fitting a magnetic system filter, which prevents sludge and debris from entering your boiler and causing damage, providing long-term protection.

Additional Power Flush Benefits In addition to saving costs through improved central heating efficiency, a power flush can enhance hot water temperatures, accelerate radiator convection, and offer reassurance with reduced risk of boiler breakdowns.




How to identify signs that your central heating system may require a power flush:
-
Inefficiency and heat loss: Poorly maintained heating systems can lead to the accumulation of sludge, deposits, rust, and debris in pipes, radiators, and the boiler. These blockages restrict water flow throughout the heating system, resulting in heat not reaching all areas and leading to wasted money.
-
Insufficient hot water: Blocked pipework or heat exchangers due to excessive buildup could cause your heating system to produce little or no hot water.
-
Cold spots on radiators: If your radiators are cold at the bottom but hot at the top, it could indicate a sludge problem in your heating system. Cold spots are caused by the buildup of iron oxide sludge, which collects at the bottom due to its weight, restricting the flow of hot water.
-
Discoloured water when bleeding radiators: Bleeding your radiators can enhance heat circulation and convection. However, if the water is discoloured during this process, it may suggest that your heating system requires a power flush.
-
Pump or valve issues: Black oxide sludge can cause increased wear and tear on pump shafts and bearings, leading to pumps seizing or failing. A stuck valve could result in an inefficient radiator.
-
Hidden signs: Even if you're not experiencing any of the above symptoms, your heating system could still be accumulating sludge and debris over time. It's recommended to power flush your heating system every five years to prevent buildup and maintain efficiency.
