Power Flushing. What is it?

Power flushing is the expression used in the heating trade to denote the process by which the radiators, pipework and sometimes boiler are forcibly cleaned using water at high velocity but at a low pressure, so that no damage to the system occurs.
A machine with a powerful pump is connected to the heating circuit to enable a high flow rate of water into the heating circuit which can effectively purge the system of sludge, scale and other corrosion products.
Once the debris and sludge have been mobilised the power flushing machine pump forcibly expels it from the system using a high velocity of fresh water.
To make the process even more effective chemicals are often added depending on the system type and nature of the problem.

Why do I need a Power Flush?

• The problem - black metal oxide sludge (rust) the build up of this sludge in your central heating system over a period of time is inevitable especially if the
system water is left untreated of any chemicals such as a inhibitor.
• When the sludge in a heating system starts to build up typical problems are:
• Radiators cold at the bottom
• Radiators cold at the top and need frequent bleeding
• No heat distribution to the radiators or very poor
• Boiler cutting out
• Noise from boiler
• Poor or no hot water
• High Fuel Bills
• Boiler failure
• By far the greatest risk to a untreated system is boiler failure - a expensive and disruptive occurrence. A improperly or unprotected system with a build
up of sludge may suffer boiler noise (thumping, drumming and knocking) due to excessive lime scale or sludge build up. Eventually the insulating effects
of sludge and lime scale will restrict the heat exchanger (the engine of a boiler) to the point where it overheats and fractures.
• Sludge will seriously effect the efficiency of a system which will lead to higher fuel bills and premature failure of a boiler and other heating components such as valves and pumps

The Solution and long term protection

• Power flush – Coltherd Heating & Plumbing use the most proven method to make sure your central heating system is flushed to a standard that exceeds
BS7593.
• Using the power flushing machine in conjunction with a filter connected to the heating circuit it is possible to eliminate sludge from your central heating
circuit and restore heat, efficiency, protection and cut your fuel bills!
• Once your system is sludge free we make sure it stays that way by adding a rust inhibitor at the correct dosage to give your system long term protection.
