Central Heating Power Flush Service
Power flushing is an effective means to clean your central heating system including, pipework, radiators and your boiler. There are a number of benefits resulting from a power flush to your central heating system and a number of reasons why you should consider a power flush now.
Total Boiler Failure
If no other fault exists on your boiler but it still show problems it could be over heating due to excessive build up of sludge and deposits restricting heat transfer. If your boiler has failed because of sludge build up it may void your warranty.
In untreated boilers debris in the form of sludge, rust and scale deposits accumulate and restrict the flow of water and heat from reaching all parts of the system. Inevitably you will turn up your heating system to compensate, which will cost you more on your energy bills.
Pump or Valve Seizure
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.
Little or no Hot Water
This could be a result of blocked pipes or a blocked heat exchanger due to an excess build up of sludge or deposits.
If your radiators are cold at the bottom but still hot at the top this could indicate sludge build up in your system. This is caused by a build up of iron oxide sludge at the bottom of your radiator which results in a restriction of the flow of water.
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’s heat exchanger, causing it to make knocking and kettling noises). This also prohibits efficient heat transfer.
After your system has been power flushed you will see the benefits instantly. Internally your system will be running much more efficiently, effectively and cleaner, you may also notice immediate improvement externally such as reduced boiler noise or more heat in your radiators. It is perhaps the long term benefits that best describe the usefulness of power flushing:
