GTS Plumbing & Heating use the best powerflushing machines available. If you are suffering from the following Powerflushing may help..
Pump or valve seizure and failure - Black oxide sludge increases shaft and bearing wear which is the most common cause of sticking pumps or complete pump failure. A completely stuck valve could result in a cold radiator or at the very least a very inefficient one.
Cold radiators - If your radiators are cold at the bottom but hot at the top this indicates sludge build up in your system. This is caused by a build up of iron oxide sludge at the bottom of your radiator (as the sludge is heavier than water) which results in a restriction of the flow of water.
Frequent venting and air at the top of radiators - Hydrogen, sometimes mistaken for air, is a by-product of electrolytic corrosion.
Sludge and scale - Black Oxide sludge forms continuously in all unprotected central heating systems as a result of corrosion. It will also harden into scale on the hottest surfaces of a system (i.e the boiler heat exchanger causing it to make knocking and kettling noises). This also prohibits efficient heat transfer.

It must be noted that even if you are not currently experiencing any problems your system may still contain sludge and corrosion. If you can not vouch for the cleanliness of your system it is advised to get it checked to be safer than sorry.
