Full power-flush from £350
Power-flushing is a process used to clean central heating systems. It involves circulating chemicals and water through the system at high velocity to remove any build-up of sludge, rust or debris. Power-flushing is recommended for systems that are experiencing issues such as cold spots on radiators, strange noises or reduced efficiency.
The power-flushing process typically involves the following steps:
1. The heating system is isolated and drained down.
2. A powerful power-flush machine is connected to the system and chemicals are added to break down any sludge or debris.
3. The power-flush machine circulates the chemicals and water through the system at high velocity, dislodging any debris.
4. The dirty water is flushed out of the system and replaced with clean water.
5. The system is refilled and treated with inhibitor to prevent future build-up.
Power-flushing can take several hours to complete depending on the size of the system and the severity of the build-up. It is important to use a qualified engineer who has experience in power-flushing.
There are several benefits to power-flushing your central heating system. These include:
1. Improved efficiency - removing sludge and debris allows heat to be distributed more evenly throughout the system, which can improve efficiency and reduce energy bills.
2. Increased lifespan - power-flushing can help extend the lifespan of your heating system by reducing wear and tear on components.
3. Improved performance - power-flushing can help restore lost performance, such as faster heating times and hotter radiators.
It is recommended that central heating systems are power-flushed every 5-6 years to maintain efficiency and prevent issues from arising.
In conclusion, power-flushing is an effective way to clean central heating systems and improve efficiency, lifespan and performance. It is important to use a qualified engineer who has experience in power-flushing to ensure that the process is carried out safely and effectively.
Radiators cold at the bottom?
This is one of the main signs your central heating system needs a power-flush. Sludge will start to build up at the bottom of your radiators causing the middle bottom of your radiators to stay cold or very slowly warm up.
Black or Brown water
Black or brown water when airing/bleeding your radiators is a sure sign your central heating system needs cleaning. Sludge (Rust) discolours the water in your heating system.
Noisy boiler or pump
If your central heating pump is making strange noises this is a clear sign that your pump is struggling and becoming blocked with sludge then a power-flush is usually necessary.
