powerflush your system

Do I need a Powerflush?

A question that we get asked quite a lot, how often do you need to powerflush your system? For those who don’t know what a powerflush is, let start with the basics.

What is a Powerflush?

A Powerflush is a cleansing procedure which is carried out on your heating system using a Powerflush pump. The aim of the Powerflush is to remove dirt, sludge, debris and rust from inside the pipes of the heating system.

Why it is necessary to do this?  It’s because, over time, the dirt and sludge builds up in the system and makes the heating system inefficient.  if it is not done, the dirty water causes damage to your boiler.

Do I need a Powerflush?

This all depends on whether your system is dirty. If you have never had one carried out before and this is a new heating system, then you should probably get one carried out now to clean your system.  It may be that you have had a boiler fault and has been told you that you have to get a powerflush carried out before they will replace boiler parts.

Make a checklist on if you have these:

  • Cold radiators or dirty bleed water?
  • Boiler cuts out and makes noises?
  • A cold home due to blocked pipes?
  • Tepid water or temperature fluctuates?

If you experience any of the above symptoms it may be time to have your central heating system chemically flushed by Logical Heating & Plumbing Solutions a powerflush bromley company.

If your system is dirty and you don’t get it cleansed using a Powerflush, then you will most likely damage your boiler and your system will become ineffective as your boiler struggles to heat up the radiators.

Does Power flushes really work?

Powerflush really does clean out the system water.  If you have a boiler fault before the Powerflush is done, the Powerflush is unlikely to fix that problem.  This would be the first step to getting your boiler repaired.   It is advise to Powerflush the system before you replace boiler parts.

How does Power flushing increase heating efficiency?

Efficiency is improved after a Powerflush because, once the system water is cleansed, the water flows more easily through the pipes.  If you imagine your boiler as the heart and the pipes as the arteries, it will help to explain how it all works.  The freer the water flows around the system, the less effort for the boiler.

Why do boiler manufacturers ask for a Powerflush to be carried out when a boiler is installed?

Boiler manufacturers require that a Powerflush is carried out at the time of boiler installation in order to maintain your boiler warranty. This is because, if a new boiler is fitted onto a system which has dirty system water, there is more likelihood of damage being caused to the boiler.  In cleansing the system water, the boiler is protected to some degree.  Similarly, most manufacturers require the boiler to be serviced annually as well.  This is because a maintained boiler is less likely to fail.

A quick guide on Powerflush

A quick guide on Powerflush

Powerflush is a cleansing process which aims to not only remove but eliminate deposits of sludge, rust and any other debris from your central heating system.

These toxins, if left, can seriously affect the efficiency of a heating system and in severe cases can damage the central heating all together.

Signs that you might need a Powerflush

Look for a number of signs before deciding to go ahead with the Powerflush process. These include cold areas on radiators, excessive noise from the boiler or the heating system pump, discoloured water when you bleed the radiators and the slow warming of the heating system. You might also notice the tap water getting cloudy, especially if there is a build-up of lime scale as well.

The Powerflush process

The generally aim of a Powerflush is to restore the full circulation of water around the central heating system, it can also eliminate noise from the boiler and the pump as well. This means that the entire central heating system has to be flushed in order to get the best results.

A qualified heating engineer will connect a powerful high flow/low pressure pumping unit to the central heating system; either to the circulation pump in the regular boiler systems or the pump head in combination boilers.  To finish it off with the help of high strength cleansing chemicals will also flush out anything in the system.

The chemicals used during a Powerflush include a sludge crust breaker and remover to help get rid of rust and sludge, a descaler to break down lime scale and a corrosion inhibitor to stop further rusting from occurring. The crust breaker and remover are acid-based so that they help to combat any rust present and any other debris, such as sand particles, that might have settled in the radiators, pipes and boiler. At the end of the process there is no acid left in the central heating system’s water.

Cost and time needed for a Powerflush

Logical Heating & Plumbing Solutions power flushing  engineer state that a full Powerflush will take around 6 hours to complete. This is an estimate though as some badly affected heating systems will require more time whilst others may be finished quicker.

The price of a full system Powerflush varies with location and the size of the heating system and can range from approximately £350 up to £1200+. Occasionally the descaler isn’t included in the original quoted price and needs to be paid for on top.

It is important that your central heating system is as efficient at all times and although a Powerflush can be an expensive process, it can also save a lot of money over time with regards to your heating bills but should be used in conjunction with a complete boiler service for best results.

The process is clean and safe when done by a professional and can quickly eliminate cold radiators and noisy boilers and pumps.

bleed a radiator

How to Bleed a Radiator

 The severe weather seen late last winter is due for a comeback with temperatures in places set to hit -20. It is important to make sure you are fully prepared on how to bleed a radiator.

If you do face any problems over the cold snap that isn’t easily fixable by yourself, it’s always best to call a plumber before the problem gets any worse, saving cost in the long run.

Why bleed a radiator?

In your property you may notice that sometimes although the heating is on the radiator is not warm at the top of the radiator but is at the bottom. This is because systems can occasionally get air in them, blocking the water from flowing through the system correctly. This air needs to be removed to get the full potential from you heating system. This is known as bleeding the system.

Tools required:

Radiator Bleeding Key

Towel (optional – just in case)

Elbow Grease!

STEP ONE: Turn off your boiler. Make sure your boiler is off to prevent further air entering the system when you bleed it.

STEP TWO: Open the Valves. The majority of radiators will have two valves at the base which control the water in and out of the radiator make sure these valves are open before moving on to the next step.

STEP THREE: Place the bleed key in the bleed screw, the bleed key is designed to fit snugly over the screw; however over time the soft metals of both key and screw can deteriorate if this is the case a spanner can also be used.

Turn the key anti-clockwise slowly until you hear a hissing sound. This is the air escaping the system keep your towel handy as water may then escape radiator once the air has emptied. Once water escapes simply turn it clockwise until it is tightly closed.

This will need to be repeated on all radiators.

Powerflushing Explained – A quick guide

Powerflushing Explained – A quick guide

For many people who have not heard the term ‘powerflushing’ before, they might alone know what the benefits are to a central heating system. Here is Powerflushing Explained – A quick guide so you never get stuck.

To put it simply, powerflushing is a procedure that is carried out in your home using a specialist pump. This procedure is carried out to resolve problems with the central heating or when a new boiler is installed.

  • It will cure flow and circulation problems in a central heating system.
  • It restores the system efficiency which will ultimately mean that the boiler doesn’t have to work so hard to pump water around the central heating system. (Ultimately saving you money)
  • It will help radiators to heat up evenly, preventing you getting cold patches at the top of the radiator.
  • It will clean the whole central heating system including underfloor pipework.
  • It will cure or prevents boiler noise and minimises the boiler warranty problems.

How is powerflushing carried out?

The powerflushing pump is connected to the system across the flow and returns the pipework. All debris and corrosion is then dislodged by the flow generated by the pump. The dislodged material is then flushed through the pump’s drain. At the same time, the pump is also filling the system with fresh water, from the cold water’s main. The last thing is then the inhibitor is added to ensure that the system continues to stay clean. How successful is power flushing? It all depends on the level of heating system corrosion that has occurred beforehand, as it can cure most circulation problems but cannot undo corrosion and gradual decay.

When hiring a plumber, they should be able to solve these problems and may recommend a power flush for the heating system.
The primary aim of power flushing the central heating is to remove all the sludge (iron oxide) which results in the radiators not heating up properly and generally blocks all the pipe work connecting the boiler to the radiators.

Power Flushing The Heating System

Power Flushing The Heating System

If you are experiencing problems with your central heating system, remember that a lot can be solved by simply power flushing the heating system.

Cleaning the central heating system is essential to its longevity, and the method of power flushing is popular due to the comprehensive clean it delivers.

You may need to clean the system if you are experiencing one or a combination of problems such as:

• Slow warming of the heating system.
• Some radiators not warming up at all, others with cold spots.
• Boiler cuts out regularly.
• Leaky radiators.
• Sludge in feed or expansion tank.
• Discoloured water when radiators are bled.

When hiring a plumber, they should be able to solve these problems and may recommend a power flush for the heating system.
The primary aim of power flushing the central heating is to remove all the sludge (iron oxide) which results in the radiators not heating up properly and generally blocks all the pipe work connecting the boiler to the radiators.

Removing the sludge and blockage involves draining the central heating system down and introducing chemicals. Once this process is done, the system is cleaned with fresh water and an inhibitor is added for future protection.
How successful is power flushing? It all depends on the level of heating system corrosion that has occurred beforehand, as it can cure most circulation problems but cannot undo corrosion and gradual decay.

Heating systems which have been neglected over a period of time or have not been treated with an effective corrosion inhibitor may have compacted corrosion debris in the pipe work, radiators or boiler. It is possible that even after the power flush some heating systems may not be fully effective or may cease to work due to the amount of sludge and debris breaking loose and collecting in the heat exchanger.

When you hire Logical Heating And Plumbing Solutions ltd you will be advised on the pros and cons of power flushing and all plumbers will be qualified and insured to carry out the work you have requested.
