Power flushing increases heating efficiency

London central Heating systems, that use hot water circulation, will often have deposits and sediments that come from the minerals in the water. These will coat the pipes and reduce their capacity to carry water. This can affect the efficiency of the heating. This efficiency can be maintained if the sludge and sediments are removed from the system at regular intervals. The air inside pipes can also lead to rust which adds to the sludge buildup.

Heating systems that use this form of heating are often referred to as central heating. They function by having water heated in furnaces or boilers and then circulated through a pipe network that reaches all the living spaces that need heating. The heat from the water is dispersed to the area to be heated through radiators or other heat transfer devices. Central heating power flushing is one of the required maintenance procedures that have to be undertaken at yearly intervals, to ensure that the system is cleared of all sludge. This flushing can also help in issues with heating radiators, contamination in the heating unit or boiler, any problems that can arise with the pump that circulates the water. It can also help to reduce corrosion in the system and any problems with pressures in piping that can come from blockages.

A Power Flush of the system can increase the life of the pump, as the load on it is reduced when all solid contaminants are removed. This process also leads to better heating and the elimination of any cold patches or areas. The entire system becomes efficient and this can lead to lower fuel bills. The heat performance of the boiler will also be enhanced, as there will be less load on it.

The presence of deposits in a system can easily be detected by bleeding the radiator. The heating system is in need of flushing if the water that comes out is cloudy or dirty. Central heating powerflushing is carried out with machines that can be connected at the tail point of radiators. These machines pump in water at high velocity that acts to dislodge all the sludge and other deposits in the pipework. It is customary to add cleaning chemicals to the water being pumped through these machines, as this helps in the process.

The condition of the system and its size can dictate the time required to complete the powerflushing of a heating system. Four hours is a minimum, though larger systems can take as much as eight hours. It is necessary to constantly check the condition of water, which is at a low pressure, during the power flushing. Once the water is clean, the machine can again be allowed to clean the system with clean water, so that any trace of the cleaning chemicals is removed.

Water used in central heating systems needs to be pH neutral, as then there will be less build up of sediment and deposits from the minerals in the water. Carry out this process regularly and it will extend the life of your system and its heating efficiency.
