MagnaCleanse Vs Power Flush and Chemical Flush: Which Is Best?

If you’re good at keeping on top of your boiler maintenance, you may know all about the importance of a full flush for your central heating system. If not, you need to know what they are and why they are needed for a perfectly functioning system.

The big question, however, is which type of system flush you should go for. Until the MagnaCleanse arrived on the scene, it was very much a case of the powerflush vs chemical flush debate and deciding on which was less harmful for your system. In this guide, we’ll explain the different types of system flush, and also why our engineers would recommend the MagnaCleanse over the other types to ensure your boiler and whole system works to the best of its ability.

Why do you need a system flush?

If a flush isn’t carried out as and when it needs to be, the water in your boiler will eventually be contaminated with rust and other unwanted elements. Over time, the rust, debris and dirt will turn into a ‘sludge’ like substance, preventing your system from functioning as well as it should.

Without the right type of flush, your system could become inefficient or even left out of order. As you can imagine, this will result in the need for a replacement boiler or an engineer to come to your property to fix the issue, which isn’t desirable.

Depending on the boiler you have in your home, you may only need a flush once every 5 or so years. A copper heat exchanger will be much more durable and corrosion resistant than stainless steel, so you may need a flush more often or less often depending on the type you have. If you’re unsure or would like some advice on when your boiler’s next flush is due, chat with an engineer using our website’s life chat feature.

We’d always recommend a MagnaCleanse over other types of flush. This is because it’s approved by our manufacturer partners and it is a highly effective way to keep your system protected. Performing a powerflush on an older system for example, can cause yet more problems. We’ll always do what is best to protect your boiler and heating system.

The magnacleanse, power flush and chemical flush

What is a MagnaCleanse?

The MagnaCleanse system flush is the latest process to rid your system of those harsh, unwanted materials. It thoroughly cleans your entire system and consistently provides boiler and pipe protection. The added benefit of a MagnaCleanse filter helps to collect sludgy residue away from your system for easy disposal. We carry out a MagnaCleanse system flush free with every boiler installation. This will ensure your system will stay as new as possible for as long as possible.

What is a power flush?

A central heating power flush is one of the older cleaning processes for a central heating system. It’s a solution of chemicals that travel through your system and its pipes, removing debris, dirt and rust, as well as any other unwanted waste material.

What is a chemical flush?

A chemical flush differs from a power flush in the fact that it uses gravity to empty the system and refill it. During this process, the right chemicals are dispersed around the system to remove unwanted materials and residue. The system is given a flush with clean water and boiler inhibitor to ensure it is fully protected.

How to flush a central heating system.

Here is how to flush a system in the three main ways:

How to MagnaCleanse a central heating system.

Before you MagnaCleanse a system, it’s important to drain it completely, then connect the MagnaClease RapidFlush filter to your system valves using the provided hoses. The MagnaCleanse cleaning solution can then be added to the system. By combining the flush components with quality cleaning chemicals, you’ll have a special formula ready to intensely clean your system at a high strength. The sludge will be collected in the filter which can be easily disposed of.  

After this, a VibraClean tool is used for a few seconds on each of your radiators in turn, which will loosen any remaining debris. When you’re satisfied with the heat of each radiator, you can move onto the next. The whole process can take as little as 2 hours.

How to power flush a central heating system.

It should always be an engineer’s job to carry out the power flush. To set up a boiler for a flush, a pump will be connected to your central heating system. Depending on the type of boiler you have, the pump will be connected to either the pump head or the circulation pump.

An engineer will then pump a chemical solution through the system, which will remove the debris and rust we mentioned earlier. The solution will include a descaling agent as well as other chemicals that will prevent rust from forming. The waste materials will then be collected and disposed of safely by an engineer.

How long does a power flush take?

The power flush can be quite a lengthy process, but the results will be more than worth the wait. The process could take from around 5 hours to 10 hours, but this completely depends on a number of factors:

  •        The number of radiators you have in your home.
  •        How old your current boiler system is.
  •        The amount of ‘sludge’ substance in your pipes/system.

Throughout the process, an engineer will look for other problems, such as any current blockages or potential new blockages that could occur in the future. Some boiler components may need replacing or cleaning to ensure it doesn’t run into any more problems. If your boiler hasn’t had a flush for some time, or if it is clear your boiler isn’t in the best condition, the process may require more time to be completed.

How to chemical flush a central heating system.

A chemical flush is a more basic version of the powerflush but can be just as effective. The chemicals are flushed through the system using gravity instead of a pump. As the cleaner is flushed around the system from the boiler, any debris will be caught by a magnetic filter.

When the work is complete, an engineer will be able to show how much your system has improved after the flush by measuring radiator temperature and comparing it to what it was previously.

The engineer will test your boiler and heating system to ensure everything is in a good working order. From doing so, they’ll usually be able to identify the areas in which there is a build-up of ‘sludge’ and if there are any leak risks. They’ll also be able to give you aftercare advice and ways you can get the most out of your system.

How to spot the signs.

  • If you’re unsure when your system is due for a flush, there are a number of signs you can look for in the way your system and boiler function.
  • Is your boiler breaking down/needs to be restarted regularly?
  • Do your radiators have cold patches while turned on, especially at the bottom?
  • Is your tap water discoloured or cloudy?
  • Do your radiators take a long while to heat up or do they not get warm at all?
  • Are your radiators or boiler quite noisy?
  • When bleeding radiators, is the water cloudy? Maybe there is no water at all.
  • If you answered ‘yes’ to any of these questions, your system may need a flush. It’s also a good idea to schedule in a system flush if you have a new boiler installed to ensure it’s in top working condition.

The advantages of a professional MagnaCleanse system flush.

Looking after your central heating system is advantageous for so many reasons. From a deep clean of your system and pipes, you’ll ensure your boiler is more energy efficient and much more reliable than it would be without a flush. Because the system will be clear of debris, it will run much smoother, increasing its lifespan. One of the main benefits of a MagnaCleanse flush is the fact that it can be completed within as little as two hours.

With a fully cleaned system, the chance of a breakdown will be very slim. You’ll have hotter radiators which will heat up more quickly. The cost of regularly replacing parts from a poor functioning boiler will be eliminated and you’ll have peace of mind that you can trust your heating system to deliver to a high standard each day, as you’d expect it to.

What is the MagnaCleanse, chemical or power flush cost?

The cost of a flush to be completed will entirely depend on a number of factors; a main factor being the complexity of your system, as well as the size of it. Engineers will also need to keep in mind that there is the possibility they could run into a problem, which could hold the job up further.

The total flush cost can vary from many engineers, ranging from around the £300-£700 mark. There may also be an additional cost depending on if there is any extra work needed or any part replacements required for an efficiently working system.

The MagnaCleanse price is free of charge if you purchase a boiler from us. The flush comes as standard with all our installations.

Choose a MagnaCleanse and extend the life of your central heating system.
