Power Flushing, Jet Flushing or Hard Flushing
A powerflush, jetflush or hardflush is a cleansing process where central heating systems are forcibly cleansed using water and chemicals at high velocity but with low pressure so as not to cause any damage to the system its self.
The objective is to remove deposits of sludge, rust and any other debris from the radiators and pipe work and restore systems with circulation problems or boiler noises caused by the murky water and corrosion deposits. Power flushing can remove these deposits and the problems that they cause, this means that the entire system has to be flushed in order to get the best results.
Do I Need A Powerflush?
Some of the main signs that you could need a power flush include cold areas on radiators (usually at the bottom), excessive noise from the boiler or the heating system pump, discolored brown/black water when you bleed/vent the radiators and a general slow warming of the central heating system.
The Power Flushing Process
A central heating engineer will connect a powerful high flow, low pressure pump unit to the central heating system. With the added help of some specially formulated high strength cleaning chemicals the engineer will flush out the system.
Most powerflushing professionals will state that a full powerflush should take around 5-6 hours to complete. This is an estimate though as not all heating systems are the same size or some badly affected heating systems will require more time whilst others may be finished quicker.
The benefits of powerflushing
Power flushing your heating system and boiler will create a more efficient system. This occurs because there will be improved circulation through the radiators and central heating pipe work and in turn the boiler will not have to work as hard to heat the house and water. Therefore the overall result is to save money on your gas bills. Power flushing can also be used in conjunction with the new MagnaCleanse magnetic filtration technique.
