Power Flushing

Are You In Need a Power Flush In Tenbury Wells?

If you have been told or think you have issues that relate to having sludge, scale or sediment within your heating system, and you are looking for the best company you can use to deal with the issues, you are in the right place!

We are power flushing central heating systems and resolving related issues like clockwork. We are one of the leading providers in the Tenbury Wells area, and we have a great wealth of knowledge and experience to deal with related issues.

We follow the Approve Codes of Practices set out by the Domestic Water Treatment Association and ensure the water we flush within the heating system is physically examined, checked with a TDS meter and PH checked before inhibitor treatment.

The principles of power flushing may seem simple, pump water with chemicals around a central heating system to clean it, but in reality, it takes expertise which comes from a whole lot of experience to perfect the method so that the maximum amount of sediment is removed without causing issues within the central heating system.

As a result, the majority of power flushing is done wrong. Many consumers can end up paying far more trying to resolve sludge, scale and sediment related issues that what they need to. From paying to flush multiple times to causing damage to the system from the incorrect methods and chemicals, there are many ways in which the process can be done wrong and cause further issues and costs.

“Sludge and scale are the leading cause of premature boiler and heating system failure. Any boiler that beats the lifetime statistics usually has clear system water within it that contains inhibitors, whereas boilers that are regularly having issues will almost always have dirty system water. There are a large number of heating systems that would benefit from a power flush, potentially saving the owners a lot of money in the long run.”

What Is Power Flushing?

Power flushing is a powerful technique where a high velocity, a low-pressure pump, known as a power flushing machine, is used extract unwanted sediment and unwanted matter, such as flux, sludge, scale, & bacterial formations from wet central heating systems.

The Correct Way To Power Flush

The most effective way is usually to remove the central heating pump from the system and connect the power flush machine through hoses to this point. Sometimes there are dedicated power flushing connection points, or a magnetic filter is installed, which in some cases, power flushing can be as equally effective when done through these points. Power flushing elsewhere, such as through radiators, will often result in less effective results. It is not always avoidable, but we advise against it unless necessary.

The Correct Use Of Chemicals

Using best practices, the right equipment and the most suited chemicals at the proper doses will increase the chances of power flushing success. Strong acid-based chemicals, which we prefer, will often be more effective than using a single flush product due to there aggressive nature. Most non-acidic power flushing chemicals are less effective, and in our opinion, can be a complete waste of time.

We commit to dedicated, specialist power flushing acid chemicals, such as Scale Breaker & FX2, instead of the use of such products as X800 on existing central heating systems.

Sludge and limescale are the common solids that can be found in central heating systems, along with flux residues. Blockages and restrictions can be caused by these within central heating systems, preventing the flow of water and the transfer of heat, leading to related issues. The power flushing chemicals we advocate will usually breakdown such unwanted matter and allow it to be mobilised in the system water by the power flushing unit or dissolve it into gases that escape during the process. Dense and aged blockages, especially in micro-bore pipework (8 & 10mm) are not always possible to remove, even with the use of strong chemicals in high concentrations.

Power Flushing Microbore Systems

To make it clear, micro-bore systems can be effectively power flushed, but the lower smaller diameter pipes restrict the flow of water. In some rare instances, deposits are too hard, and there is not any flow to resolve the issue. It must be recognised that there are limitations to power flushing, although there are additional methods that can be utilised to increase effectiveness. The more obstacles put in the way of the process, the less effective it will be.

Blockages From Building Aggregates

Building materials that may have contaminated the heating system during the installation process, such as sand, cement and plaster will often not be broken down by the chemicals. Where hardened, the power flushing process may struggle to remove such material.

Related issues tend to occur in new-build properties due to central heating systems being installed in stages. Were workers have left heating pipes open during the first fix process, it can allow debris from the site to contaminate the heating system.

Why Power Flushing Can Not Always Remove Everything

Small pockets of sediment can get trapped in radiators where the flow of water becomes restricted. When sediment gets trapped, it is usually in one or more of lower level radiators, more so when on micro-bore pipework. Usually, it will just be a small amount of dirty fluid in the bottom of the radiator that will run clear quickly when drawn off. This is one of the reasons why advise lockshield radiator valves with drain-offs are fitted on all low lever radiators to allow for the removal of trapped sediment and ease of maintenance in the future.

Conventional Heating Systems

Header tanks (F&E tanks) that feed traditional central heating systems are disconnected during the process to prevent fluid overflow back into the tank. Over long periods, F&E tanks can become heavily soiled with contaminants such as sediment and when reconnected to the system will reintroduce
unwanted matter back into the heating system. Where an F&E tank is accessible, we advise that the tank is removed and cleaned out during the power flushing process. However, inspection and/or the removal of F&E tanks are not always practical, due to possible locations. In such instances, if the client is not willing to pay for a replacement tank, the client must accept that sediment and other contaminants were left in the tank may re-enter the system.

Can Power Flushing Cause Leaks?

Power flushing will not cause leaks, but it can highlight defects in the heating system. Fittings that have not been correctly jointed, such as unsoldered fittings, or radiators or valves that sludge or limescale has been holding together are examples of this.

Issues with components may become visible because the cleaning process removes the corrosion/limescale/sludge, and water now can pass. Although not typical, if these problems do occur the cost of power flushing does not include the cost to such defects.

Is Power Flushing Effective?

Power flushing is the best way to make significant improvements to the longevity and efficiency of a central heating system that contains sludge, scale or other sediments. Central heating systems containing either will often have increased maintenance costs, plus a decrease in efficiency.

Power flushing, coupled with inhibitors post-treatment, ultimately allows components to last longer, increases performance and improves energy efficiency within the system.

Common Problems Caused By Sludge/Scale/Sediment

Conventional systems:

  • Radiators heat up when the system is set for hot water only
  • Hot tap water getting scalding hot
  • Hot tap water failing to heat up
  • Reduced pump life
  • Reduced motorised valve life
  • Kettling from the boiler
  • Overheating of the system
  • Cold spots in radiators
  • System water “pumping over” into the F&E tank
  • Thermostatic radiator valves failing to work

Combination (Combi) boilers:

  • Radiators getting warm when systems demand is for hot water only
  • Hot tap water getting scalding hot
  • Hot tap water has fluctuating temperatures
  • Hot tap water failing to heat up
  • Reduced pump life
  • Kettling from the boiler
  • Overheating of the system
  • Cold spots in radiators
  • Thermostatic radiator valves failing to work

System Water Analysis

Sludge, when in sufficient quantities, will be visible in the system water in the form of a dark black to brown matter. Limescale cannot be detected visually in the water and only becomes noticeable when it solidifies to form a white deposit.

Using a combination of visual test equipment, electronic test equipment and experience is the best route to go about identifying the presence of sediment in a system. These techniques will not tell you precisely what contaminants are in the heating system, the only real way to determine precisely what is present in the heating system is to collect several water samples and have them tested in a laboratory. This is an expensive and time-consuming process that is not generally used in domestic situations.

Post Power Flushing

After a heating system has been power flushed correctly, inhibitors are added to reduce the corrosion process, and the accumulation of limescale and biological contamination.

There are multiple inhibitor products on the market, all that vary in their effectiveness. In our experience, most appear to work reasonably well to very well when added to a correctly cleansed/power flushed system. Trusted brands we have used have kept systems free from any contamination for well over ten years.

We use Fernox, Sentinel and Adey inhibitor products, all of which perform exceptionally well over sustained periods.

Frequently Asked Questions

Yes, but not with acid-based chemicals! Aluminium reacts readily with acids and strong alkaline, thus less effective compounds must be used, or the boiler needs disconnecting from the heating system where acid-based chemicals need to be used.

It is very high, 99% of the time it will resolve the issue(s) without any further work. However, it will not be fully effective in certain situations.

The process its self will not create leaks, but where components within the heating system are being held together by debris, the removal of the debris can result in parts weeping/leaking. These situations are rare, and where it does happen, it is usually a weep on such things as radiator valves.
