What Are The Benefits Of Power Flushing

What are the benefits of power flushing? Find out how power flushing can benefit the efficiency of your central heating. 

Over time the various systems in your home such as the central heating system, electrical system and hot water system will succumb to wear and tear. Simply leaving them to their fate without maintenance will result in them breaking long before they are supposed to.   

The central heating system, in particular, becomes significantly less effective at heating your home as it gets older. This can be caused by a malfunction like a pump or a valve seizure, or contamination in the pipes. The best way of dealing with this and revitalising your central heating system is to get a power flush.

Powerflushing is a process that thoroughly cleans out all of the internal piping of your central heating system, clearing away any and all forms of blockages, clogs, limescale, rust and debris. This deep cleaning ensures that there is nothing inside the system to interfere with water flow. 

As such, the hot water for your central heating can be delivered to heat your home with no obstruction and maximum efficiency. 

While the main benefit of a power flush is cleaning any existing blockages in the pipe system, the service offers a couple of other benefits. Much like brushing your teeth, performing a powerwash cleans the clogs and grime while acting as a corrosion inhibitor to help prevent sludge buildups in the future. 

Once you have had a power flush, you will find that your radiators work better, and you receive lower energy bills as well.  

Powerwashing is also a completely safe and fast process when performed by a qualified professional, so you don't need to worry about something going horribly wrong. 

Signs your heating system needs power flushing.

Obviously, nobody can see into their houses plumbing at all times to find out whether or not any blockages have built up, but that doesn't mean there aren't any methods of finding out. 

There are two tell-tale signs that you should look for when considering the necessity for a powerwash. 

The first sign is loud noises coming from your boiler. To be specific, it should sound like clanging and whistling noises. These noises are caused by the build-up of limescale inside the boiler. This noise doesn't just occur when you turn on the heating either; it should constantly be happening.  

The next sign to keep an eye out for is cold spots or cold strips on your radiators. If your radiators are only hot at the top, it's a sign that your central heating needs power flushing. 

This is a direct symptom of your central heating system circulation being inhibited and causing an inability to pump water through the radiators effectively due to the build-up of sludge and debris. 

When this occurs, you will also notice an increase in your energy bills because the boiler has to work a lot harder to provide the required heating to compensate for the lost heat in the radiators. 

What happens during a Powerflush 

Powerflushing your central heating system is a process that involves the use of a specialised pumping machine that can force fluids through the piping of your boiler and the rest of your house at extremely high pressure. The liquid initially pumped through the system is not water; it is a cocktail of chemicals designed specifically to break down any clogs or iron oxide sludge inside the pipes and clean it out. 

The power flushing should not take too long, but ultimately its length depends on the size of your home. For the average household, the whole power flushing should take roughly 8 hours. so it is a good idea to perhaps go out for the day, and by the time you get back home, it will be done. 

Should the power flushing be performed on a larger property with a more complicated central heating system such as an office building, the time, it takes to complete increases significantly up to potentially 2 days. Even though that seems like a long time, it's worth remembering that this is still the fastest and most efficient method of cleaning your plumbing. 

Once the process is completed, the engineer will wash out all of the chemical solution with clean water to remove any chance of contamination. 

When should you get a system Powerflush?

You should give your central heating system a good power flushing when it is either heavily contaminated by sludge, clogs and bacteria or when you know you are going to get a new boiler installed.

This is because there is a good chance that your old central heating system is going to affect your new boiler just as much as it is going to affect the old pipework. This means that if there is any limescale, rust, or problematic bacteria in your system, it will promote those same deposits in the new boiler. 

This could result in your shiny new boiler breaking down more often, recusing its efficiency and having a shorter lifespan. Therefore in order to ensure the longevity of your newly installed boiler, you should consider getting a power flushing service.

Who should perform a Powerflush?

If you find that your central heating system does need a power flush, you will undoubtedly wonder who to call. While there are no legal requirements that state you must be a gas safe engineer to perform a powerflush services, it is highly recommended that you hire one anyway. 

While the process itself is pretty safe, there are several things that can go wrong that can leave your central heating system worse for wear if the powerflushing is performed improperly. Not to mention that the chemicals involved in a powerflush are actually quite toxic to humans, so handling them comes with some inherent risks. 

Therefore for your peace of mind and the safety of your boiler and central heating system, you should always hire a gas safe registered engineer to perform a powerflush as they are the most competent and reliable heating engineers you will find.
