A Powerflush is a cleansing process which aims to remove deposits of sludge, rust and any other debris from your central heating system. These contaminants, if left, can seriously affect the efficiency of a heating system and, in severe cases, a powerflush could be the only option available. Over time the water in your pipes, boiler and radiators deposits unwanted by-products like rust. This rust (plus other dirt and debris) becomes an unpleasant, mud-like substance that professionals affectionately refer to as ‘sludge’.
Sludge in your heating system can cause blockages and corrosion which will lead to both inefficiency and / or breakdown. In extreme cases it can be so damaging that a complete boiler replacement is needed.
If you carry out regular servicing and maintenance (professional servicing is recommended annually) then a preventative Powerflush should only be necessary every 5-6 years to clear debris and prevent significant blockages.
IMPORTANT: If you are planning to replace your boiler it’s important that the engineer performs a Powerflush before the installation. Otherwise, you risk contaminating the new boiler with damaging sludge and debris that’s hanging around in the old pipework. This will also void your manufacturers warranty.
Here are signs to look out for that suggest that all is not well in your central heating system.
If any of these problems sound familiar to you, it’s time to contact an experienced engineer. While a Powerflush may be all that is required to get your heating back on track, unfortunately it is not always that simple. A system may be so damaged that it is actually cheaper to replace rather than repair.
