Sludge builds up in a central heating system naturally over time due to the constant flow of water through the system causing rusting, with limescale build up an additional problem for hard water areas such as London. A power flush is the most effective way to remove sludge from a badly affected central heating system, usually taking between 4 and 8 hours for one of our experienced engineers from Central Heating Flush to complete, depending on the size and condition of the central heating system. A MagnaClean filter can be attached to the system to remove future build up of sludge from the central heating system.

It is important to remove sludge from a central heating system to prevent problems developing and to improve the efficiency of the system, which will in turn, reduce your energy bills. Problems that may develop from sludge build up if you do not remove it include, loud boiler noises, the boiler or radiators becoming slow to warm up, radiator cold spots and fluctuating hot water temperature, these problems can lead to the breakdown of the central heating system, which may be costly to repair.

A power flush machine, used to remove sludge from a central heating system, is attached to the system at a convenient point for you, often the tails of a radiator, and pumps water and cleaning chemicals through the whole central heating system at high velocity. The water is pumped at low pressure to remove sludge from a central heating system, preventing any damage to the central heating system. The sludge flows out from the central heating system to a filter attached to the power flush machine until only clean pH neutral water is left in the central heating system.

Central Heating Flush recommend attaching a MagnaClean filter to the central heating system following a power flush to remove future sludge build up from the central heating system, maintaining the level of efficiency achieved by the power flush.

The easiest way to check if you need to remove sludge from your central heating system is to bleed a radiator. Dirty water indicates the build up of sludge, and a power flush is wise to remove the sludge from the central heating system to prevent problems developing.

If a central heating system is 10 or more years old, it is wise to remove sludge from the system, as a lot will have built up in this length of time, reducing the efficiency of the central heating system. If a new boiler is being fitted to an existing central heating system, then it is essential to remove sludge from the existing central heating system first. This is because new boilers have much more narrow passageways to improve their efficiency, which leave them more vulnerable to the damage caused by sludge build up. A new boilers warranty may be invalid if you did not remove the sludge from the existing central heating system prior to its installation.
