Powerflushing

Why should I Powerflush?

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

* Cold spots on radiators.
* Blocked radiators.
* Radiators frequently needing venting & bleeding.
* Boiler noise.
* Noisy pump.
* Pump failure.
* Heating circulation problems
* System is slow to heat up
* Reduced heating output.
* Pinhole leaks from radiators.
* Blocked inoperative or leaking radiator valves.

When a new heating system is installed in your house, corrosion starts immediately. The oxygen in the water starts to attack the radiators internally. This chemical reaction eventually forms a black sludge that causes problems such as boiler noise, repeated pump failures or poor circulation and often all three!!!

Sludge!

Sludge is the principle cause of system replacement. It is present in the majority of heating systems as a thin, black liquid. However, it is often thick and oily. At this stage it is highly damaging to a system's performance and will ultimately cause system failure if left unchecked..

What is Powerflushing?

Power Flushing is the process by which heating systems are forcibly cleansed using a chemical at high velocity, but low pressure, so that no physical damage is caused to the system. The objective is to remove sludge and corrosion deposits from the system which cause damage to the boiler and pump, slowing down circulation, leading to higher fuel costs. In our experience, power flushing can make a dramatic difference to the operating efficiency of most systems.

Furthermore many maintainance companies often insist that systems are powerflushed in order to maintain a cover plan.
