The build up of sludge/debris in hot water central heating systems is inevitable, no matter what fuel source is used. Over a period of time this sludge can block pipes and prevent the radiators/heat emitters from distributing heat around your house/office.

Scale build up within the boiler and pipes can cause unpleasant noises and very loud banging in the pipework.

Sludge and scale can also seriously affect the efficiency of your central heating system; it will lead to higher fuel bills and can bring forward the time when you need to replace some or all of the system.

The solution?

Remove sludge and scale by power flushing your central heating system

The process we carry out on a powerflush is as follows:

We firstly connect the powerflush machine and magnetic filter to either a radiator or the heating pump, which ever is most practical and accessible. We then run the central heating system and powerflush machine together until it reaches approximately 60 degrees. Then we add the cleaning chemicals which is suited to the design, material and size of the system into the flush machine to be circulated around the heating system.

The central heating system and flush machine will then be allowed to run for a minimum of one hour, depending on the severity of the sludge/debris in the system and the volume of water within the pipes. The severity of the sludge/debris will show on the magnetic filter, which will catch any sludge or debris passing through the flush machine.

Once this process is complete we begin to flush each individual radiator/ heat emitter. We switch off all radiators and then turn them on one by one flushing them individually. Until the magnetic filter is clean.

After this is carried out, we then turn all radiators back on and carry out a dump cycle (cold flush)to rejunivate the system with fresh water.

This is achieved by turning off the boiler and introducing fresh water to the system. The fresh water will enter the system and push the contaminated central heating water out through the magnet, to the dump and then into the drain. Using the same process with the individual radiators/ heat emitters stated previously.

Finally when the water runs clean and there's no trace of contaminated water. We then introduce correct amount of inhibitor according to the size of the system and reinstate the central heating system. Checking the system is running correctly.

On some rear occasions the process of the powerflush is not always a hundred percent effective if the system is severly blocked and contanimated. Other alternatives may need to be taken.
