Central Heating Power Flushing

What are the benefits of a Central Heating Flush?

Heating Cost

Reduced fuel bill (up to 25%)

Efficiency

Improves central heating efficiency

System Clean

Cleans the whole system, including under floor heating and pipes

Pump Life

Increased pump life

Heat

Increased output from radiators

Noise

Boiler noise reduction

Corrosion

Prevents hydrogen gases building up which then cause corrosion to the system


Does my central heating system need a Flush?

IF YOUR CENTRAL HEATING SYSTEM HAS ANY OF THE FOLLOWING PROBLEMS, IT WOULD BENEFIT FROM A CENTRAL HEATING FLUSH.

 

Dirty Water?

Radiator water is black

Slow Heating Time?

Central heating takes time to heat up

Bleeding Radiators?

Radiators need regularly bleeding

Boiler Cutting Out?

Boiler turning on and off

Noisy Boiler?

Excessive noise from boiler

Pump Problems?

Pump has failed or noisy pump

Cold Spots On Radiators

Radiators are partially cold

Radiator Problems?

Radiators blocked with sludge or leaking radiators

The above problems can be attributed to bacteria, corrosion, and sludge forming within your central heating system.

Central Heating Flushing can give your system a new lease of life and improve its overall efficiency.

How to know if a central heating flush of your central heating system is required?

If a central heating system has insufficient corrosion inhibitor from the day your heating system was installed it starts to deteriorate. The steel and iron components will start to rust the system. This leads to bacteria, the formation of magnetite and a build up of black sludge which is evident by the water in the system. As the build up of black sludge increases it can block pipework and radiators and have a negative effect upon the efficiency of your central heating system, leading to higher energy bills and the failure of components eg. heating pump, radiator valves, pipework or the heat exchanger in your boiler.

If you notice radiators which are cold at the bottom, you probably have a build up of black sludge and flakes of rust blocking the fins within the radiator. If your radiators have cold areas on the top it may just be due to air in the system or it could be caused by hydrogen gas which forms due to bacteria which is a part of the corrosion process.

The following are all symptoms of corrosion::
• Blackwater/sludge in the system.
• Radiators need regular bleeding.
• Radiators not very hot.
• Central heating slow to warm up.
• Noise coming from the boiler.
• Central heating pump not working.

If you are experiencing any of these symptoms then your central heating system could benefit from flushing.

How is a central heating flushing carried out?

To start the process a chemical cleaning agent is added to the system and left to circulate around the system, cleaning pipework, radiators and the boilers heat exchanger. The whole job can take many hours and once the system has been thoroughly cleaned, the inhibitor is then added to the central heating system to prevent future corrosion and bacteria building up.

Why should I clean and flush my central heating system?

If you are installing to your system a new high efficiency boiler then flushing out the system is recommended if you want to realize the energy efficiency levels of 90% plus from your boiler manufacturer. Your new boiler cannot be expected to meet its full potential if your heating system is contaminated with sludge and bacteria. Modern boilers have much smaller waterways and are therefore far more prone to clogging than old boilers. Many boiler manufacturers recommend that the system is thoroughly flushed and cleaned as a requirement of their extended warranty. Flushing out your central heating system can save up to 25% on the overall running costs as part of increasing its efficiency.
