Powerflushing is the quickest and most efficient way to clean heating systems with minimal disruption and dismantling. It is the process which is used to flush out heating systems using water at high velocity, but low pressure. It usually involves the addition into the system of powerful cleansing chemicals and mobilising agents.
Damson can also use Power Flush machines that have built in heaters, in case the heating appliance in the system being flushed is not functional.
These chemicals and agents clean heating systems by removing flux, sludge and other debris which has collected in the heating system over the years. 
Damson have many years experience of Powerflushing, so if you need a Power Flush in Dorset, Hampshire, Bournemouth or Poole, call Damson now on 01202 872272. 

How is Powerflushing carried out?

The powerflushing pump is connected to the system across the flow and return pipework. All debris and corrosion is then dislodged by the flow generated by the pump. The dislodged debris and corrosion is then flushed through the pump's drain. At the same time, the pump fills the system with fresh water from the connection to the cold water main.

When should I Powerflush?

  • Prior to fitting a new boiler
  • Cold or partially cold radiators
  • Radiators that need to be bled regularly
  • When radiator water is dirty
  • Kettling noises from boilers
  • Noises in pipes
  • When you start experiencing pump failures

Circulation & Noise Problems?

There are thousands of ageing central heating systems with circulation and boiler noise problems caused by accumulations of sludge, corrosion, debris and scale. Some clients try to remove sludge by installing chemical mobilising agents directly into the system and then repeating the process some weeks later. This is fine for systems that only have a minimal amount of debris. However, for systems that are suffering from sludge, it really is best to get your system power flushed. Power flushing will cure most circulation problems.

Fitting A New Boiler

Boiler manufacturers recommend that a heating system should be power flushed immediately before a new boiler is fitted to an existing system. Some manufacturers even make the boiler's warranty conditional on this.  When a new boiler is fitted, the system alterations and high efficiency of the new boiler can dislodge accumulated debris which has been in the system for years. This is why boiler manufacturers are reluctant to carry out warranty repairs where it is suspected that the fault has been caused by debris and sludge in the system. Only by powerflushing can you be sure that a system really is clean to the standards demanded by modern high efficiency boilers and heat exchangers.

Clear Radiator Sludge 

Radiators that are cold or partially cold are often this way because there may be sludge trapped in them.  The sludge tends to sink to the bottom of the radiator. This is why radiators can sometimes feel cold at the bottom and hot at the top. If the sludge is removed by powerflush, then the water is able to circulate around the whole radiator rather than just the top part of that radiator.

Damson use a powerflushing machine that incorporates a large magnet, that traps the sludge, and is then removed and disposed of. Using this type of machine can dramatically reduce the time taken to powerflush a system.
