Power Flushing

Do You Need A Central Heating Power Flush In Ludlow?

If you have, or if you believe that you have issues that relate to having sludge, scale or sediment within a central heating system, you are in the right place. We are the best company to deal with related issues!

We are power flushing experts who undertake related work on central heating systems all the time. We are one of the leading providers in the area, and we have a great wealth of knowledge and experience in the field.

We stick to Approved Codes of Practices set out by the Domestic Water Treatment Association. We do this by ensuring that the water we flush within a heating system is physically examined, checked with a TDS meter and PH checked before inhibitor treatment.

It takes a lot of skill and experience to do power flushing in a way that makes it highly effective. As a result, most power flushes are done wrong. Many consumers have to pay twice or more to resolve sludge, scale and sediment related issues. Should it be from paying to power flush multiple times, having to replace pipework that could have been resolved with a correctly administered flush, or even having to pay to repair damage caused by incorrect flushing, there are many ways the customer can loose out.

“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 process where a high velocity and low-pressure pump, known as a power flushing machine, is used to remove sediment and other unwanted matter from a water-containing central heating system.

The Correct Way To Power Flush

A power flushing machine is best connected at the central heating/boilers pump. Sometimes other connect points can be used, such as magnetic filter is installed, to a good effect. Power flushing through radiators, especially microbore. will often result in less effective results. It is not always avoidable, but we advise against it unless necessary.

The Correct Use Of Chemicals

The right equipment, chemicals at the proper doses and equipment will produce the best results. We like to use strong acid-based chemicals wherever possible as this will often be more effective than non-acidic products. Non-acidic power flushing chemicals are less effective, and in our opinion, can be a complete waste of time.

Sludge and limescale are the common offenders that cause problems in the central heating system. These and other contaminants can cause blockages and restrictions, preventing the flow of water and the transfer of heat, leading to related issues. The power flushing chemicals we use will usually breakdown this matter and allow it to be moved out of the system in the system water by the power flushing.

Power Flushing Microbore Systems

We commonly power flush micro-bore systems with great effect, but the lower smaller diameter pipes restrict the flow of water. In some rare instances, when deposits are too hard and established, and there is not enough flow, power flushing may not be entirely successful. There are limitations to power flushing. 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 can not cause leaks where defects do not already exist so long as the process is done correctly. Fittings that have not been correctly jointed, such as unsoldered fittings, or components that sludge or limescale has been holding together are examples where leaks can occur with power flushing. 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

Once a heating system has been power flushed correctly, inhibitors are introduced to the system water to reduce the corrosion process, including the accumulation of limescale, and sometimes biological contamination.

In our experience, most inhibitors on the market appear to work reasonably well to very well when added to a correctly cleansed/power flushed system. Fernox, Sentinel and Adey product we have used have kept systems free from any contamination for many years.

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.
