What is a Powerflush?

Over time, your central heating system will collect a build-up of materials such as sludge and rust within it, which can hamper the efficiency of the system. A powerflush is a cleaning process that is designed to remove these materials, allowing your central heating to return to an efficient state. This article will detail the key points of a powerflush, so you can be aware of your options should your central heating system encounter a problem.

How it works

A powerflush uses a high flow, low pressure pumping system in conjunction with high strength chemicals to eliminate the build-up of materials that can affect the efficiency of your central heating system. The chemicals that are used have the ability to break down sludge and remove limescale from the inner workings of the central heating, as well as what is known as a ‘corrosion inhibitor’ that helps prevent further rusting.

How long does it take?

The amount of time a full powerflush takes to complete can vary depending on the state of your heating system, but the average time is estimated to be around six hours. However, if your central heating is particularly damaged, this time is likely to be increased in order for you to experience the full benefit.


As with the duration of the powerflush, the cost can vary. The size and location have an impact on how much you can expect to pay, with smaller systems costing less to clean and ones in more accessible locations also requiring less expense. In general, powerflush costs range from £350 to in excess of £1200, but it is a worthwhile expenditure when you take into account the results that you can get. Although a powerflush might seem like a large expense at the time, when compared to the money you can save on regular repairs it can prove to be excellent value for money. If you are experiencing issues with your heating, whether it is taking a long time to come into effect or your energy bills are higher than normal, it could be because of a build-up in your system. In this case, a powerflush is the best solution to your issue.
