Why Your Central Heating System Might Benefit from a Flush


Is your heating system performing as well as it used to? Are your radiators heating up evenly? Has the system become noisier? Is the tap water not as hot as it used to be? Any or all of these things could be a symptom of your heating system being clogged up with rust and sludge. This affects its performance and wastes fuel.

More than half of what you spend on your domestic fuel bills goes on space heating and hot water, so if your system is not working at full efficiency, it could be costing you a lot of money.

The Answer

Fortunately, there is a solution to the problem that doesn’t involve a new boiler or major modifications. That is to have the system flushed. The process, known as power flushing, removes any sludge, rust and other debris from your system. This allows the water to circulate more effectively, leading to more efficient operation and a saving in fuel costs.

Having a power flush carried out by a company such as Glowzone Brighton boiler repair can extend the life of your system. You should also have a flush carried out before fitting a new boiler, as this ensures that you’ll get the best from the installation and won’t invalidate the boiler’s warranty.

How It Works

When you ask for a power flush from a company offering boiler repair in Brighton, what happens is that an engineer will connect a power flush machine to your system. This can be either at a radiator, at the boiler or at a pump coupling – whichever is a convenient point. The machine then pumps water and cleaning fluids through your system at low pressure so as not to damage your system. However, it uses a high velocity in order to dislodge any debris that may have built up in the pipes and radiators.

A power flush will usually take around five to eight hours to fully complete – the exact time needed will depend on the size and condition of your heating system. After flushing, your system will be refilled with water and corrosion inhibitor and left ready to run. Once it’s complete, you should find that your system operates more effectively and more quietly, and you should see a consequent reduction in your energy bills.
