The lowdown on a power flush. What it is, how long does it take and how does it work. Many people often question the recommendation from their plumber or engineer for a power flush. However this is often down to a lack of knowledge and confusion, it is often a very important and useful process.
A power flush is a cleaning process which aims to remove any rust, sludge, lime scale and any other corrosive deposits from your central heating system. Most companies will highly recommend a power flush to you to make it more efficient which will, in the long run will save you money.
Of course for them it is a fair money spinner as the process is far from cheap. Still many will also recommend that you have a power flush if you are having a new boiler fitted. This can help clean the system for the new installation as well as avoid voiding the warranty of an existing boiler.
So how does it work? Typically one of their engineers will connect a power flush machine to your heating system. Depending on what type of system you have this will either be on the radiators, boilers or combination of both. The machine itself uses water and cleansing chemicals to power flush at high velocity through the whole system. Think colonic irrigation for your central heating system. This whole process will normally take anything between 4-8 hours depending on the size and condition of your existing system.
The engineer will then test that full circulation around the system has been restored before completion. All engineers you hire should be fully qualified in this procedure as suffice to say, there is large scope for things to go a bit wrong.
Remember a power flush can potentially solve many common central heating problems such as noise, cold spots and inconsistent water temperature however it is not always entirely essential.
