Book a power flush central heating upgrade service

power flush central heating

Is your central heating not working as well as it once was? Before changing systems, a power flush central heating service could get your existing system back up and running as efficiently as when it was brand new.

When central heating systems are first installed, they are as clean and bright as a new pin. As long as the thermostat is set correctly, and the heating source (electricity, gas or oil-fired) is working perfectly, any central heating system will work well.

But after months and years of service, any central heating system that pumps water around to carry the heat to the radiators will begin to clog up. It’s unavoidable unless you organise a regular power flush central heating service.

What does a power flush central heating service entail?

Power Flush is a specific trade name. It refers to a particular type of central heating system cleansing. It uses a special technique whereby jets of water are produced under low pressure but at high velocity.

These water jets are sprayed into the central heating system. These jets remove the build-up of both corrosion and sludge in the pipes, the radiators the coils and heat exchangers.

The benefits of power flushing

A Power Flush central heating service not only improves the heat quality the system delivers throughout your home. It will also assist in reducing the cost of your heating bills. This is because your central heating system will operate more efficiently. Another benefit of power flushing is that it will also extend the working life of the system.

After power flushing, you will find that the radiators heat up more rapidly. Also, the hot water will be able to be distributed without any blockages. This results in the heating being distributed between the various rooms in your home that much more evenly. It means less strain being exerted on your hot water boiler.

When sludge is allowed to build up in your central heating it will contribute to the earlier failure of the system. If you power flush central heating on a regular basis you can prevent the system from a premature break-down.

Maximise the efficiency of your new boiler

There is another thing that should be borne in mind too if you are getting a new boiler installed. By power flushing the central heating system prior to the installation, it will ensure your new boiler works to maximum efficiency.

Power flushing central heating is not only recommended for domestic properties. It also works well and provides benefits in industrial premises too.

When central heating systems run for years on end without being properly maintained, they will, over several years, accumulate lots of sludge inside the piping, and the radiators. This leads to inefficient central heating systems in London. It causes blockages, slows circulation, and makes it much more difficult for radiators to heat up, and keep warm.

The result is that boiler installations will have to work much harder, as will your water pump. It will hit you hard where it hurts most – your wallet, if left to completely corrode your central heating system, meaning you will need to install a new boiler and radiators.

The build up of sludge in central heating systems can cause your boiler to go wrong at the most inconvenient time, leaving you cold & out of pocket

Most people are anxious to save money when it comes down to their heating bills, and getting regular maintenance done is something that many people shy away from until something goes wrong. The problem is that whenever these things do go wrong, it’s never at the right time. In fact, it is usually the most inconvenient time.

The importance of regular boiler maintenance

It is of course necessary to have any gas appliances regularly maintained. As well as ensuring that they won’t let you down unexpectedly, (in the middle of a cold spell during winter for example), it’s also an opportunity to make sure that they are burning the gas properly, and don’t emit any carbon monoxide. It’s also key to make sure that the engineers you choose to do the maintenance are properly gas safe qualified, as all of our fitters are at CW Services, Plumbing & Heating. It’s one of the things that make us one of the most trustworthy boiler maintenance London based companies there is.

We won’t bleed you dry – not in the financial sense anyway

If households were to have their central heating systems bled at the same time they service the boiler, this would also help to safeguard the system’s operation. It would help stop any central heating system from eventually becoming very inefficient, and it’s something that CW Plumbing (central heating service specialists) could easily and cheaply do for you at the same time. It’s cheaper of course because it only involves one house call, and not two.
