Central heating system and heating system protection
Many central heating systems suffer from poor circulation as a result of a build-up of oxide sludge and calcium in the pipework and radiators. This sludge not only greatly reduces the efficiency and performance of your central heating system but can result in costly repairs to your boiler and central heating system components.
Much can be done to prevent damage and maintain efficiency of your boiler, radiators and heating system components in the future however if your system is suffering from some of the symptom listed below it is likely that cleaning the system; either by powerflushing, chemical cleaning or magnetic cleansing. Cleaning the system is recommend before installing any system protection devices and corrosion inhibitor should also be added.
"Does my central heating system need a powerflush?"
- Things to look out for...
- Cold areas on radiators
- Excessive noise either from central heating circulation pump or boiler
- No water escapes when you bleed a radiator
- Discoloured water when you bleed the radiators
- Radiators are slow to heat up
- Certain radiators do not heat up as well as others
- Radiators are cold but pipes are hot
- Boiler regularly shuts down and needs restarting
What is a Powerflush?
If your heating system requires a powerflush and not doing so will almost certainly exacerbate the problems and symptoms experienced. The circulation through the pipes and the radiators will continue to slow and less and less heat will be emitted by radiators. This makes the system and your boiler increasingly vulnerable break downs and damage. It may also create complete blockages which are not curable by powerflushing.
Whilst powerflushing is not always 100% successful especially in severe cases where pipes are completely blocked, the normal result of powerflushing is that the boiler and the rest of the central heating system become more efficient. This occurs as there is now much improved circulation through the pipes and radiators and in turn the boiler does not need to work so hard to warm your home. Successful cleaning of your central heating system will increase efficiency and performance and will also reduce your energy bills and also the likelihood of breakdowns. After having a powerflush it is recommend that system protection in the form of corrosion capture devices (magnetic / dirt) are installed for maximum protection against reoccurrences of build-up of corrosion products. It may also be recommend to convert traditional heating systems to a sealed system, which are less susceptible to corrosion.
